Tests

Tests are in the test folder. run.sh executes all files found in the test_cases folder and compares the output (stdout, stderr and return status) of minishell to the one of bash.

Usage:

• ./run.sh to execute all tests except bonus tests
• ./run.sh a or ./run.sh b to also execute the tests in test_cases/bonus
• ./run.sh /builtins/echo to execute only the tests in a specific file

Test cases are formatted like test_name command to execute; cmd 2; cmd3 (that is a tab in there). ;s are replaced by newlines, this allows for executing multiple commands per test, even if minishell does not support ;.

test_ast.sh is used to test the parsing into an abstract syntax tree without executing anything.
