LuaUnit documentation master file, created by - - sphinx-quickstart on Thu Aug 21 21:45:55 2014. - You can adapt this file completely to your liking, but it should at least - contain the root `toctree` directive. - - -,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,, -Welcome to LuaUnit's documentation! -,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,, - -Introduction -************ - -LuaUnit is a popular unit-testing framework for Lua, with an interface typical -of xUnit libraries (Python unittest, Junit, NUnit, ...). It supports -several output formats (Text, TAP, JUnit, ...) to be used directly or work with Continuous Integration platforms -(Jenkins, Hudson, ...). - -For simplicity, LuaUnit is contained into a single-file and has no external dependency. To start using it, -just add the file *luaunit.lua* to your project. A `LuaRocks package`_ is also available. - -.. _LuaRocks package: https://luarocks.org/modules/bluebird75/luaunit - -Tutorial and reference documentation is available on `Read-the-docs`_ . - -.. _Read-the-docs: http://luaunit.readthedocs.org/en/latest/ - -LuaUnit also provides some dedicated support to scientific computing. See the section `Scientific computing and LuaUnit`_ - -LuaUnit may also be used as an assertion library. In that case, you will call the assertion functions, which generate errors -when the assertion fails. The error includes a detailed analysis of the failed assertion, like when executing a test suite. - -LuaUnit provides another generic usage function: :func:`prettystr` which converts any value to a nicely -formatted string. It supports in particular tables, nested table and even recursive tables. - - -More details -************ - -LuaUnit provides a wide range of assertions and goes into great efforts to provide the most useful output. For example -since version 3.3 , comparing lists will provide a detailed difference analysis: - -.. code-block:: lua - - -- lua test code. Can you spot the difference ? - function TestListCompare:test1() - local A = { 121221, 122211, 121221, 122211, 121221, 122212, 121212, 122112, 122121, 121212, 122121 } - local B = { 121221, 122211, 121221, 122211, 121221, 122212, 121212, 122112, 121221, 121212, 122121 } - lu.assertEquals( A, B ) - end - - $ lua test_some_lists_comparison.lua - - TestListCompare.test1 ...

See `Using the command-line`_ . - -LuaUnit is very well tested: code coverage is 99.5% . The test suite is run on every version of Lua (Lua 5.1 to 5.3, LuaJIT 2.0 and 2.1 beta) -and on many OS (Windows Seven, Windows Server 2012, MacOs X and Ubuntu). You can check the continuous build results on `Travis-CI`_ and `AppVeyor`_ . - -.. _Travis-CI: https://travis-ci.org/bluebird75/luaunit -.. _AppVeyor: https://ci.appveyor.com/project/bluebird75/luaunit/history - -LuaUnit is maintained on GitHub: https://github.com/bluebird75/luaunit . We gladly accept feature requests and even better Pull Requests. - -LuaUnit is released under the BSD license. - - -Installation -============ - -LuaUnit is packed into a single-file. To make start using it, just add the file to your project. - -Several installation methods are available. - -LuaRocks --------- - -LuaUnit v3.3 is available as a `LuaRocks package`_ . - -.. _LuaRocks package: https://luarocks.org/modules/bluebird75/luaunit - -GitHub ------- - -The simplest way to install LuaUnit is to fetch the GitHub version: - -.. code-block:: bash - - git clone git@github.com:bluebird75/luaunit.git - -Then copy the file luaunit.lua into your project or the Lua libs directory. - -The version in development on GitHub is always stable and can be used safely. - -On Linux, you can also install it into your Lua directories - -.. code-block:: bash - - sudo python doit.py install - -If that fail, edit the function *install()* in the file *doit.py* to adjust -the Lua version and installation directory. It uses, by default, Linux paths that depend on the version. - - -Upgrade note -================ - -**Important note when upgrading to version 3.1 and above** : there is a break of backward compatibility in version 3.1, assertions functions are no longer exported directly to the global namespace. See :ref:`luaunit-global-asserts` on how to adjust or restore previous behavior. - - -LuaUnit development -=================== - -See `Developing luaunit`_ - -Version and Changelog -===================== -This documentation describes the functionality of LuaUnit v3.2 . - -New in version 3.3 - 6. Mar 2018 --------------------------------- -* General - * when comparing lists with :func:`assertEquals`, failure message provides an advanced comparison of the lists - * :func:`assertErrorMsgEquals` can check for error raised as tables - * tests may be finished early with :func:`fail`, :func:`failIf`, :func:`success` or :func:`successIf` - * improve printing of recursive tables - * improvements and fixes to JUnit and TAP output - * stricter :func:`assertTrue` and :func:`assertFalse`: they only succeed with boolean values - * add :func:`assertEvalToTrue` and :func:`assertEvalToFalse` with previous :func:`assertTrue`/:func:`assertFalse` behavior of coercing to boolean before asserting - * all assertion functions accept an optional extra message, to be printed along the failure -* New command-line arguments: - * can now shuffle tests with ``--shuffle`` or ``-s`` - * possibility to repeat tests (for example to trigger a JIT), with ``--repeat NUM`` or ``-r NUM`` - * more flexible test selection with inclusion (``--pattern`` / ``-p``) or exclusion (``--exclude`` / ``-x``) or combination of both -* Scientific computing dedicated support (see documentation): - * provide the machine epsilon in EPS - * new functions: :func:`assertNan`, :func:`assertInf`, :func:`assertPlusInf`, :func:`assertMinusInf`, :func:`assertPlusZero`, :func:`assertMinusZero` and - their negative version - * in :func:`assertAlmostEquals`, margin no longer provides a default value of 1E-11, the machine epsilon is used instead -* Platform and continuous integration support: - * validate LuaUnit on MacOs platform (thank to Travis CI) - * validate LuaUnit with 32 bits numbers (floats) and 64 bits numbers (double) - * add test coverage measurements thank to coveralls.io .

Jun 2005 ---------------------------------- -* first public release - - -Version 1.1 ------------- -* move global variables to internal variables -* assertion order is configurable between expected/actual or actual/expected. See `Equality assertions`_ -* new assertion to check that a function call returns an error -* display the calling stack when an error is spotted -* two verbosity level, like in python unittest - - -Getting started with LuaUnit -**************************** - -This section will guide you through a step by step usage of *LuaUnit* . The full source code -of the example below is available in the : :ref:`source-code-example` or in the file *my_test_suite.lua* -in the doc directory. - -Setting up your test script -=========================== - -To get started, create your file *my_test_suite.lua* . - -The script should import LuaUnit:: - - lu = require('luaunit') - -The last line executes your script with LuaUnit and exit with the -proper error code:: - - os.exit( lu.LuaUnit.run() ) - -Now, run your file with:: - - lua my_test_suite.lua - -It prints something like:: - - Ran 0 tests in 0.000 seconds, 0 successes, 0 failures - OK - -Now, your testing framework is in place, you can start writing tests. - -Writing tests -============= - -LuaUnit scans all variables that start with *test* or *Test*. -If they are functions, or if they are tables that contain -functions that start with *test* or *Test*, they are run as part of the test suite. - -So just write a function whose name starts with test. Inside test functions, use the assertions functions provided by LuaUnit, such -as :func:`assertEquals`. - -Let's see that in practice. - -Suppose you want to test the following add function:: - - function add(v1,v2) - -- add positive numbers - -- return 0 if any of the numbers are 0 - -- error if any of the two numbers are negative - if v1 < 0 or v2 < 0 then - error('Can only add positive or null numbers, received '..v1..' and '..v2) - end - if v1 == 0 or v2 == 0 then - return 0 - end - return v1+v2 - end - -You write the following tests:: - - function testAddPositive() - lu.assertEquals(add(1,1),2) - end - - function testAddZero() - lu.assertEquals(add(1,0),0) - lu.assertEquals(add(0,5),0) - lu.assertEquals(add(0,0),0) - end - - -:func:`assertEquals` is the most commonly used assertion function. It -verifies that both argument are equals, in the order actual value, expected value. - -Rerun your test script (``-v`` is to activate a more verbose output):: - - $ lua my_test_suite.lua -v - -It now prints:: - - Started on 02/19/17 22:15:53 - TestAdd.testAddPositive ... Ok - TestAdd.testAddZero ... Ok - ========================================================= - Ran 2 tests in 0.003 seconds, 2 successes, 0 failures - OK - -You always have: - -* the date at which the test suite was started -* the group to which the function belongs (usually, the name of the function table, and ** for all direct test functions) -* the name of the function being executed -* a report at the end, with number of executed test, number of non selected tests if any, number of failures, number of errors (if any) and duration. - -The difference between failures and errors are: - -* luaunit assertion functions generate failures -* any unexpected error during execution generates an error -* failures or errors during setup() or teardown() always generate errors - - -If we continue with our example, we also want to test that when the function receives negative numbers, it generates an error. Use -:func:`assertError` or even better, :func:`assertErrorMsgContains` to also validate the content -of the error message. There are other types or error checking functions, see `Error assertions`_ . Here -we use :func:`assertErrorMsgContains` . First argument is the expected message, then the function to call -and the optional arguments:: - - function testAddError() - lu.assertErrorMsgContains('Can only add positive or null numbers, received 2 and -3', add, 2, -3) - end - -Now, suppose we also have the following function to test:: - - function adder(v) - -- return a function that adds v to its argument using add - function closure( x ) return x+v end - return closure - end - -We want to test the type of the value returned by adder and its behavior. LuaUnit -provides assertion for type testing (see `Type assertions`_ ). In this case, we use -:func:`assertIsFunction`:: - - function testAdder() - f = adder(3) - lu.assertIsFunction( f ) - lu.assertEquals( f(2), 5 ) - end - -Grouping tests, setup/teardown functionality -===================================================== - -When the number of tests starts to grow, you usually organise them -into separate groups. You can do that with LuaUnit by putting them -inside a table (whose name must start with *Test* or *test* ). - -For example, assume we have a second function to test:: - - function div(v1,v2) - -- divide positive numbers - -- return 0 if any of the numbers are 0 - -- error if any of the two numbers are negative - if v1 < 0 or v2 < 0 then - error('Can only divide positive or null numbers, received '..v1..' and '..v2) - end - if v1 == 0 or v2 == 0 then - return 0 - end - return v1/v2 - end - -We move the tests related to the function add into their own table:: - - TestAdd = {} - function TestAdd:testAddPositive() - lu.assertEquals(add(1,1),2) - end - - function TestAdd:testAddZero() - lu.assertEquals(add(1,0),0) - lu.assertEquals(add(0,5),0) - lu.assertEquals(add(0,0),0) - end - - function TestAdd:testAddError() - lu.assertErrorMsgContains('Can only add positive or null numbers, received 2 and -3', add, 2, -3) - end - - function TestAdd:testAdder() - f = adder(3) - lu.assertIsFunction( f ) - lu.assertEquals( f(2), 5 ) - end - -- end of table TestAdd - -Then we create a second set of tests for div:: - - TestDiv = {} - function TestDiv:testDivPositive() - lu.assertEquals(div(4,2),2) - end - - function TestDiv:testDivZero() - lu.assertEquals(div(4,0),0) - lu.assertEquals(div(0,5),0) - lu.assertEquals(div(0,0),0) - end - - function TestDiv:testDivError() - lu.assertErrorMsgContains('Can only divide positive or null numbers, received 2 and -3', div, 2, -3) - end - -- end of table TestDiv - -Execution of the test suite now looks like this:: - - Started on 02/19/17 22:15:53 - TestAdd.testAddError ... Ok - TestAdd.testAddPositive ... Ok - TestAdd.testAddZero ... Ok - TestAdd.testAdder ... Ok - TestDiv.testDivError ... Ok - TestDiv.testDivPositive ... Ok - TestDiv.testDivZero ... Ok - ========================================================= - Ran 7 tests in 0.006 seconds, 7 successes, 0 failures - OK - - -When tests are defined in tables, you can optionally define two special -functions, *setUp()* and *tearDown()*, which will be executed -respectively before and after every test. - -These function may be used to create specific resources for the -test being executed and cleanup the test environment. - -For a practical example, imagine that we have a *log()* function -that writes strings to a log file on disk. The file is created -upon first usage of the function, and the filename is defined -by calling the function *initLog()*. - -The tests for these functions would take advantage of the *setup/teardown* -functionality to prepare a log filename shared -by all tests, make sure that all tests start with a non existing -log file name, and delete the log filename after every test:: - - TestLogger = {} - function TestLogger:setUp() - -- define the fname to use for logging - self.fname = 'mytmplog.log' - -- make sure the file does not already exists - os.remove(self.fname) - end - - function TestLogger:testLoggerCreatesFile() - initLog(self.fname) - log('toto') - -- make sure that our log file was created - f = io.open(self.fname, 'r') - lu.assertNotNil( f ) - f:close() - end - - function TestLogger:tearDown() - -- cleanup our log file after all tests - os.remove(self.fname) - end - -.. Note:: - - *Errors generated during execution of setUp() or tearDown() - functions are considered test failures.* - - -.. Note:: - - *For compatibility with luaunit v2 and other lua unit-test frameworks, - setUp() and tearDown() may also be named setup(), SetUp(), Setup() and teardown(), TearDown(), Teardown().* - - -Using the command-line -====================== - -You can control the LuaUnit execution from the command-line: - -**Output format** - -Choose the test output format with ``-o`` or ``--output``. Available formats are: - -* text: the default output format -* nil: no output at all -* tap: TAP format -* junit: output junit xml - -Example of non-verbose text format:: - - $ lua doc/my_test_suite.lua - ....... - Ran 7 tests in 0.003 seconds, 7 successes, 0 failures - OK - - -Example of TAP format:: - - $ lua doc/my_test_suite.lua -o TAP - 1..7 - # Started on 02/19/17 22:15:53 - # Starting class: TestAdd - ok 1 TestAdd.testAddError - ok 2 TestAdd.testAddPositive - ok 3 TestAdd.testAddZero - ok 4 TestAdd.testAdder - # Starting class: TestDiv - ok 5 TestDiv.testDivError - ok 6 TestDiv.testDivPositive - ok 7 TestDiv.testDivZero - # Ran 7 tests in 0.007 seconds, 7 successes, 0 failures - -For a more detailed overview of all formats and their verbosity see the section `Output formats`_ . - - -**List of tests to run** - -You can list some test names on the command-line to run only those tests. -The name must be the exact match of either the test table, the test function or the test table -and the test method.

Ok - ========================================================= - Ran 4 tests in 0.003 seconds, 4 successes, 0 failures, 3 non-selected - OK - -The number of tests ignored by the selection is printed, along -with the test result. The pattern can be any lua pattern. Be sure to exclude all magic -characters with % (like -+?*) and protect your pattern from the shell -interpretation by putting it in quotes. - -You can also exclude tests that match some patterns: - -Example:: - - -- Run all tests except zero testing and except error testing - $ lua my_test_suite.lua -v -x Error -x Zero - -For our test suite, it gives the following output:: - - Started on 02/19/17 22:29:45 - TestAdd.testAddPositive ... Ok - TestAdd.testAdder ... Ok - TestDiv.testDivPositive ... Ok - ========================================================= - Ran 3 tests in 0.003 seconds, 3 successes, 0 failures, 4 non-selected - OK - -You can also combine test selection and test exclusion. See `Flexible test selection`_ - -Conclusion -========== - -You now know enough of LuaUnit to start writing your test suite. Check -the reference documentation for a complete list of -assertions, command-line options and specific behavior. - - -Reference documentation -*********************** - -.. _luaunit-global-asserts: - -Enabling global or module-level functions -========================================= - -Versions of LuaUnit before version 3.1 would export all assertions functions to the global namespace. A typical -lua test file would look like this: - -.. code-block:: lua - - require('luaunit') - - TestToto = {} --class - - function TestToto:test1_withFailure() - local a = 1 - assertEquals( a , 1 ) - -- will fail - assertEquals( a , 2 ) - end - - [...] - -However, this is an obsolete practice in Lua. It is now recommended to keep all functions inside the module. Starting -from version 3.1 LuaUnit follows this practice and the code should be adapted to look like this: - -.. code-block:: lua - - -- the imported module must be stored - lu = require('luaunit') - - TestToto = {} --class - - function TestToto:test1_withFailure() - local a = 1 - lu.assertEquals( a , 1 ) - -- will fail - lu.assertEquals( a , 2 ) - end - - [...] - -If you prefer the old way, LuaUnit can continue to export assertions functions if you set the following -global variable **prior** to importing LuaUnit: - -.. code-block:: lua - - -- this works - EXPORT_ASSERT_TO_GLOBALS = true - require('luaunit') - - TestToto = {} --class - - function TestToto:test1_withFailure() - local a = 1 - assertEquals( a , 1 ) - -- will fail - assertEquals( a , 2 ) - end - - [...] - - -LuaUnit.run() function -====================== - -**Return value** - -Run your test suite with the following line:: - - os.exit(lu.LauaUnit.run()) - -The *run()* function returns the number of failures of the test suite. This is -good for an exit code, 0 meaning success. - - -**Arguments** - -If no arguments are supplied, it parses the command-line arguments of the script -and interpret them. If arguments are supplied to the function, they are parsed -instead of the command-line. It uses the same syntax. - -Example:: - - -- execute tests matching the 'withXY' pattern - os.exit(lu.LuaUnit.run('--pattern', 'withXY')) - - -**Choice of tests** - -If test names were supplied, only those -tests are executed. When test names are supplied as arguments, they don't have -to start with *test*, they are run anyway. - -If no test names were supplied, a general test collection process starts -under the following rules: - -* all variable starting with *test* or *Test* are scanned. -* if the variable is a function it is collected for testing -* if the variable is a table: - - * all keys starting with *test* or *Test* are collected (provided that they are functions) - * keys with name *setUp* and *tearDown* are also collected - -If one or more pattern were supplied, the test are then filtered according the -pattern(s). Only the test that match the pattern(s) are actually executed. - - -**setup and teardown** - -The function *setUp()* is executed before each test if it exists in the table. -The function *tearDown()* is executed after every test if it exists in the table. - -.. Note:: - *tearDown()* is always executed if it exists, even if there was a failure in the test or in the *setUp()* function. - Failures in *setUp()* or *tearDown()* are considered as a general test failures. - - -LuaUnit.runSuite() function -============================== - -If you want to keep the flexibility of the command-line parsing, but want to force -some parameters, like the output format, you must use a slightly different syntax:: - - runner = lu.LuaUnit.new() - runner:setOutputType("tap") - os.exit( runner:runSuite() ) - -*runSuite()* behaves like *run()* except that it must be started -with a LuaUnit instance as first argument, and it will use the LuaUnit -instance settings. - - -Command-line options -==================== - -Usage: lua [options] [testname1 [testname2] ...] - -**Test names** - -When no test names are supplied, all tests are collected. - -The syntax for supplying test names can be either: name of the function, name of the table -or [name of the table].[name of the function]. Only the supplied tests will be executed. - -Selecting tests with --pattern and --exclude is usually more flexible. See `Flexible test selection`_ - -**Options** - ---output, -o FORMAT Set output format to FORMAT. Possible values: text, tap, junit, nil . See `Output formats`_ ---name, -n FILENAME For junit format only, mandatory name of xml file. Ignored for other formats. ---pattern, -p PATTERN Execute all test names matching the Lua PATTERN. May be repeated to include severals patterns. See `Flexible test selection`_ ---exclude, -x PATTERN Exclude all test names matching the Lua PATTERN. May be repeated to exclude severals patterns. See `Flexible test selection`_ ---repeat, -r NUM Repeat all tests NUM times, e.g. to trigger the JIT. See `Other options`_ ---shuffle, -s Shuffle tests before running them. See `Other options`_ ---error, -e Stop on first error. See `Other options`_ ---failure, -f Stop on first failure or error. See `Other options`_ ---verbose, -v Increase verbosity ---quiet, -q Set verbosity to minimum ---help, -h Print help ---version Version information of LuaUnit - -Output formats ------------------- - -Choose the output format with the syntax ``-o FORMAT`` or ``--output FORMAT``. - -Formats available: - -* ``text``: the default output format of LuaUnit -* ``tap``: output compatible with the `Test Anything Protocol`_ -* ``junit``: output compatible with the *JUnit XML* format (used by many CI - platforms).

Ok - ========================================================= - Ran 4 tests in 0.003 seconds, 4 successes, 0 failures, 3 non-selected - OK - - -Assertions functions -===================== -We will now list all assertion functions. For every functions, the failure -message tries to be as informative as possible, by displaying the expectation and value that caused the failure. It -relies on the :func:`prettystr` for printing nicely formatted values. - -All function accept an optional extra message which if provided, is printed along with the failure message. - -.. Note:: see :ref:`table-printing` and :ref:`comparing-table-keys-table` for more dealing with recursive tables and tables containing keys of type table. - - -Equality assertions ----------------------- -All equality assertions functions take two arguments, in the order -*actual value* then *expected value*. Some people are more familiar -with the order *expected value* then *actual value*. It is possible to configure -LuaUnit to use the opposite order for all equality assertions, by setting up a module -variable: - -.. code-block:: lua - - lu.ORDER_ACTUAL_EXPECTED=false - -The order only matters for the message that is displayed in case of failures. It does -not influence the test itself. - - -.. function:: assertEquals(actual, expected [, extra_msg] ) - - **Alias**: *assert_equals()* - - Assert that two values are equal. - - For tables, the comparison is a deep comparison : - - * number of elements must be the same - * tables must contain the same keys - * each key must contain the same values. The values - are also compared recursively with deep comparison. - - If provided, *extra_msg* is a string which will be printed along with the failure message. - - LuaUnit provides other table-related assertions, see :ref:`assert-table` . - - -.. function:: assertNotEquals(actual, expected [, extra_msg]) - - **Alias**: *assert_not_equals()* - - Assert that two values are different. The assertion - fails if the two values are identical. Like the previous function, it uses table deep comparison. - - If provided, *extra_msg* is a string which will be printed along with the failure message. - -Value assertions ----------------------- - -LuaUnit contains several flavours of true/false assertions, to be used in different contexts. -Usually, when asserting for *true* or *false*, you want strict assertions (*nil* should not -assert to *false*); *assertTrue()* and *assertFalse()* are the functions for this purpose. In some cases though, -you want Lua coercion rules to apply (e.g. value *1* or string *"hello"* yields *true*) and the right functions to use -are *assertEvalToTrue()* and *assertEvalToFalse()*. Finally, you have the *assertNotTrue()* and *assertNotFalse()* to verify -that a value is anything but the boolean *true* or *false*. - -The below table sums it up: - -============ ============ =================== ================ ============= =================== =============== -**True assertion family** **False assertion family** ------------------------------------------------------------------ --------------------------------------------------- -Input Value assertTrue() assertEvalToTrue() assertNotFalse() assertFalse() assertEvalToFalse() assertNotTrue() -============ ============ =================== ================ ============= =================== =============== -*true* OK OK OK Fail Fail Fail -*false* Fail Fail Fail OK OK OK -*nil* Fail Fail OK Fail OK OK -*0* Fail OK OK Fail Fail Fail -*1* Fail OK OK Fail Fail Fail -*"hello"* Fail OK OK Fail Fail Fail -============ ============ =================== ================ ============= =================== =============== - - - -.. function:: assertEvalToTrue(value [, extra_msg]) - - **Alias**: *assert_eval_to_true()* - - Assert that a given value evals to ``true``. Lua coercion rules are applied - so that values like ``0``, ``""``, ``1.17`` **succeed** in this assertion. If provided, - extra_msg is a string which will be printed along with the failure message. - - See :func:`assertTrue` for a strict assertion to boolean ``true``. - -.. function:: assertEvalToFalse(value [, extra_msg]) - - **Alias**: *assert_eval_to_false()* - - Assert that a given value eval to ``false``. Lua coercion rules are applied - so that ``nil`` and ``false`` **succeed** in this assertion. If provided, extra_msg - is a string which will be printed along with the failure message. - - See :func:`assertFalse` for a strict assertion to boolean ``false``. - -.. function:: assertTrue(value [, extra_msg]) - - **Alias**: *assert_true()* - - Assert that a given value is strictly ``true``. Lua coercion rules do not apply - so that values like ``0``, ``""``, ``1.17`` **fail** in this assertion. If provided, - extra_msg is a string which will be printed along with the failure message. - - See :func:`assertEvalToTrue` for an assertion to ``true`` where Lua coercion rules apply. - -.. function:: assertFalse(value [, extra_msg]) - - **Alias**: *assert_false()* - - Assert that a given value is strictly ``false``.

Lua coercion rules are applied - so that values like ``0``, ``""``, ``false`` all validate the assertion. - If provided, *extra_msg* is a string which will be printed along with the failure message. - -.. function:: assertIs(actual, expected [, extra_msg]) - - **Alias**: *assert_is()* - - Assert that two variables are identical. For string, numbers, boolean and for nil, - this gives the same result as :func:`assertEquals` . For the other types, identity - means that the two variables refer to the same object. - If provided, *extra_msg* is a string which will be printed along with the failure message. - - **Example :** - -.. code-block:: lua - - s1='toto' - s2='to'..'to' - t1={1,2} - t2={1,2} - v1=nil - v2=false - - lu.assertIs(s1,s1) -- ok - lu.assertIs(s1,s2) -- ok - lu.assertIs(t1,t1) -- ok - lu.assertIs(t1,t2) -- fail - lu.assertIs(v1,v2) -- fail - -.. function:: assertNotIs(actual, expected [, extra_msg]) - - **Alias**: *assert_not_is()* - - Assert that two variables are not identical, in the sense that they do not - refer to the same value.

If *isPattern* - is provided and is true, *sub* is treated as a pattern which - is searched inside the string *str* . - - -.. function:: assertNotStrIContains( str, sub [, extra_msg] ) - - **Alias**: *assert_not_str_icontains()* - - Assert that the string *str* does not contain the substring *sub*, irrespective of the case. - If provided, *extra_msg* is a string which will be printed along with the failure message. - - Note that unlike :func:`assertNotStrcontains`, you can not search for a pattern. - - -.. function:: assertStrMatches( str, pattern [, start [, final [, extra_msg ]]] ) - - **Alias**: *assert_str_matches()* - - Assert that the string *str* matches the full pattern *pattern*. - - If *start* and *final* are not provided or are *nil*, the pattern must match the full string, from start to end. The - function allows to specify the expected start and end position of the pattern in the string. If provided, - *extra_msg* is a string which will be printed along with the failure message. - - -Error assertions --------------------------- -Error related assertions, to verify error generation and error messages. - -.. function:: assertError( func, ...) - - **Alias**: *assert_error()* - - Assert that calling functions *func* with the arguments yields an error. If the - function does not yield an error, the assertion fails. - - Note that the error message itself is not checked, which means that this function - does not distinguish between the legitimate error that you expect and another error - that might be triggered by mistake. - - The next functions provide a better approach to error testing, by checking - explicitly the error message content. - -.. Note:: - - When testing LuaUnit, switching from *assertError()* to *assertErrorMsgEquals()* - revealed quite a few bugs! - -.. function:: assertErrorMsgEquals( expectedMsg, func, ... ) - - **Alias**: *assert_error_msg_equals()* - - Assert that calling function *func* will generate exactly the given error message. If the - function does not yield an error, or if the error message is not identical, the assertion fails. - - Be careful when using this function that error messages usually contain the file name and - line number information of where the error was generated. This is usually inconvenient. To - ignore the filename and line number information, you can either use a pattern with :func:`assertErrorMsgMatches` - or simply check for the message content with :func:`assertErrorMsgContains` . - -.. function:: assertErrorMsgContains( partialMsg, func, ... ) - - **Alias**: *assert_error_msg_contains()* - - Assert that calling function *func* will generate an error message containing *partialMsg* . If the - function does not yield an error, or if the expected message is not contained in the error message, the - assertion fails. - -.. function:: assertErrorMsgMatches( expectedPattern, func, ... ) - - **Alias**: *assert_error_msg_matches()* - - Assert that calling function *func* will generate an error message matching *expectedPattern* . If the - function does not yield an error, or if the error message does not match the provided patternm the - assertion fails. - - Note that matching is done from the start to the end of the error message. Be sure to escape magic all magic - characters with ``%`` (like ``-+.?*``) . - - -Type assertions --------------------------- - - The following functions all perform type checking on their argument. If the - received value is not of the right type, the failure message will contain - the expected type, the received type and the received value to help you - identify better the problem. - -.. function:: assertIsNumber(value [, extra_msg]) - - **Aliases**: *assertNumber()*, *assert_is_number()*, *assert_number()* - - Assert that the argument is a number (integer or float). - If provided, *extra_msg* is a string which will be printed along with the failure message. - -.. function:: assertIsString(value [, extra_msg]) - - **Aliases**: *assertString()*, *assert_is_string()*, *assert_string()* - - Assert that the argument is a string. - If provided, *extra_msg* is a string which will be printed along with the failure message. - -.. function:: assertIsTable(value [, extra_msg]) - - **Aliases**: *assertTable()*, *assert_is_table()*, *assert_table()* - - Assert that the argument is a table. - If provided, *extra_msg* is a string which will be printed along with the failure message. - -.. function:: assertIsBoolean(value [, extra_msg]) - - **Aliases**: *assertBoolean()*, *assert_is_boolean()*, *assert_boolean()* - - Assert that the argument is a boolean. - If provided, *extra_msg* is a string which will be printed along with the failure message. - -.. function:: assertIsNil(value [, extra_msg]) - - **Aliases**: *assertNil()*, *assert_is_nil()*, *assert_nil()* - - Assert that the argument is nil. - If provided, *extra_msg* is a string which will be printed along with the failure message. - -.. function:: assertIsFunction(value [, extra_msg]) - - **Aliases**: *assertFunction()*, *assert_is_function()*, *assert_function()* - - Assert that the argument is a function. - If provided, *extra_msg* is a string which will be printed along with the failure message. - -.. function:: assertIsUserdata(value [, extra_msg]) - - **Aliases**: *assertUserdata()*, *assert_is_userdata()*, *assert_userdata()* - - Assert that the argument is a userdata. - If provided, *extra_msg* is a string which will be printed along with the failure message. - -.. function:: assertIsCoroutine(value [, extra_msg]) - - **Aliases**: *assertCoroutine()*, *assert_is_coroutine()*, *assert_coroutine()* - - Assert that the argument is a coroutine (an object with type *thread* ). - If provided, *extra_msg* is a string which will be printed along with the failure message. - -.. function:: assertIsThread(value [, extra_msg]) - - **Aliases**: *assertIsThread()*, *assertThread()*, *assert_is_thread()*, *assert_thread()* - - Same function as :func:assertIsCoroutine . Since Lua coroutines have the type thread, it's not - clear which name is the clearer, so we provide syntax for both names. - If provided, *extra_msg* is a string which will be printed along with the failure message. - - -.. _assert-table: - -Table assertions --------------------------- - -.. function:: assertItemsEquals(actual, expected [, extra_msg]) - - **Alias**: *assert_items_equals()* - - Assert that two tables contain the same items, irrespective of their keys. - If provided, *extra_msg* is a string which will be printed along with the failure message. - - This function is practical for example if you want to compare two lists but - where items are not in the same order: - -.. code-block:: lua - - lu.assertItemsEquals( {1,2,3}, {3,2,1} ) -- assertion succeeds - -.. - - The comparison is not recursive on the items: if any of the items are tables, - they are compared using table equality (like as in :func:`assertEquals` ), where - the key matters. - - -.. code-block:: lua - - lu.assertItemsEquals( {1,{2,3},4}, {4,{3,2,},1} ) -- assertion fails because {2,3} ~= {3,2} - - - -Ending test ---------------------- - -LuaUnit allows to force test ending, either positevely or negatively, with the following functions. - -.. function:: fail( message ) - - Stops the ongoing test and mark it as failed with the given message. - - -.. function:: failIf( cond, message ) - - If the condition *cond* evaluates to *true*, stops the ongoing test and mark it as failed with the given message. - Else, continue the test execution normally. - -.. function:: success() - - Stops the ongoing test and mark it as successful. - -.. function:: successIf( cond ) - - If the condition *cond* evaluates to *true*, stops the ongoing test and mark it as successful. - Else, continue the test execution normally. - - -Scientific computing and LuaUnit --------------------------------- - -LuaUnit is used by the CERN for the MAD-NG program, the forefront of computational physics in the field of particle accelerator design and simulation (See MAD_).

Feel also free to pick up such tasks and implement them. - -Changes should be proposed as *Pull Requests* on GitHub. - -Thank to our continous integration setup with Travis-Ci and AppVeyor, all unit-tests and functional tests are run on Linux, Windows and MacOs, with all versions of Lua. So -any *Pull Request* will show immediatly if anything is going unexpected. - - -Unit-tests -------------------- -All proposed changes should pass all unit-tests and if needed, add more unit-tests to cover the bug or the new functionality. Usage is pretty simple: - -.. code-block:: shell - - $ lua run_unit_tests.lua - ................................................................................ - ............................... - Ran 111 tests in 0.120 seconds - OK - - -Functional tests -------------------- -Functional tests also exist to validate LuaUnit. Their management is slightly more complicated. - -The main goal of functional tests is to validate that LuaUnit output has not been altered. Since LuaUnit supports some standard compliant output (TAP, junitxml), this is very important (and it has been broken in the past) - -Functional tests perform the following actions: - -* Run the 2 suites: example_with_luaunit.lua, test_with_err_fail_pass.lua (with various options to have successe, failure and/or errors) -* Run every suite with all output format, all verbosity -* Validate the XML output with jenkins/hudson and junit schema -* Compare the results with the previous output ( archived in test/ref ), with some tricks to make the comparison possible : - - * adjustment of the file separator to use the same output on Windows and Unix - * date and test duration is zeroed so that it does not impact the comparison - * adjust the stack trace format which has changed between Lua 5.1, 5.2 and 5.3 - -* Run some legacy suites or tricky output to manage and verify output: test_with_xml.lua, , compat_luaunit_v2x.lua, legacy_example_with_luaunit.lua - - -For functional tests to run, *diff* must be available on the command line. *xmllint* is needed to perform the xml validation but -this step is skipped if *xmllint* can not be found. - -When functional tests work well, it looks like this: - -.. code-block:: shell - - $ lua run_functional_tests.lua - ............... - Ran 15 tests in 9.676 seconds - OK - - -When functional test fail, a diff of the comparison between the reference output and the current output is displayed (it can be quite -long).

Increasing LuaUnit version -2. Improving or breaking LuaUnit output - -This a good place to start looking if you see failures occuring. - -Annexes -******** - -.. _table-printing: - -Annex A: More on table printing -================================ - -When asserting tables equality, by default, the table content is printed in case of failures. LuaUnit tries to print -tables in a readable format. It is -possible to always display the table id along with the content, by setting a module parameter PRINT_TABLE_REF_IN_ERROR_MSG . This -helps identifying tables: - -.. code-block:: lua - - local lu = require('luaunit') - - local t1 = {1,2,3} - -- normally, t1 is dispalyed as: "{1,2,3}" - - -- if setting this: - lu.PRINT_TABLE_REF_IN_ERROR_MSG = true - - -- display of table t1 becomes: " {1,2,3}" - - -.. Note :: table loops - - When displaying table content, it is possible to encounter loops, if for example two table references eachother. In such - cases, LuaUnit display the full table content once, along with the table id, and displays only the table id for the looping - reference. - -**Example:** displaying a table with reference loop - -.. code-block:: lua - - local t1 = {} - local t2 = {} - t1.t2 = t2 - t1.a = {1,2,3} - t2.t1 = t1 - - -- when displaying table t1: - -- table t1 inside t2 is only displayed by its id because t1 is already being displayed - -- table t2 is displayed along with its id because it is part of a loop. - -- t1: " { a={1,2,3}, t2= {t1=} }" - - -.. _comparing-table-keys-table: - -Annex B: Comparing tables with keys of type table -================================================== - - If provided, *extra_msg* is a string which will be printed along with the failure message. - - -This is a very uncommon scenario but there are a few programs out there which use tables as keys for other tables. LuaUnit has been adjusted to deal intelligently with this scenario. - -A small code block is worth a thousand pictures : - -.. code-block:: lua - - local lu = require('luaunit') - - -- let's define two tables - t1 = { 1, 2 } - t2 = { 1, 2 } - lu.assertEquals( t1, t2 ) -- succeeds - - -- let's define three tables, with the two above tables as keys - t3 = { t1='a' } - t4 = { t2='a' } - t5 = { t2='a' } - -There are two ways to treat comparison of tables t3 and t4: - -**Method 1: table keys are compared by content** - -* t3 contain one key: t1 -* t4 contain one key: t2, which has exactly the same content as t1 -* the two keys compare equally with assertEquals, so assertEquals( t3, t4 ) succeeds - -**Method 2: table keys are compared by reference** - -* t3 contain one key: t1 -* t4 contain one key: t2, which is not the same table as t1, its reference is different -* the two keys are different because t1 is a different object than t2 so assertEquals( t3, t4 ) fails - -Whether method 1 or method 2 is more appropriate is up for debate. - -LuaUnit has been adjusted to support both scenarios, with the config variable: *TABLE_EQUALS_KEYBYCONTENT* - -* TABLE_EQUALS_KEYBYCONTENT = true (default): method 1 - table keys compared by content -* TABLE_EQUALS_KEYBYCONTENT = false: method 2 - table keys compared by reference - -In any case, assertEquals( t4, t5 ) always succeeds. - -To adjust the config, change it into the luaunit table before running any tests: - - -.. code-block:: lua - - local lu = require('luaunit') - - -- define all your tests - -- ... - - lu.TABLE_EQUALS_KEYBYCONTENT = false - -- run your tests: - os.exit( lu.LuaUnit.run() ) - -.. _source-code-example: -
