* added-tests

Signed-off-by: shinigami-777 <[email protected]>

* removed comments and mvn spotless:apply done

Signed-off-by: shinigami-777 <[email protected]>

* Move test class to correct directory

Use a single JenkinsRule for the entire set of tests because we don't
need a new Jenkins instance for any of the tests.  Makes the tests faster,
especially on Windows.

* made explicit imports
