Any way to use a TestSuite (instead a TestCase) with rostest?

edit

UPDATE: See rosticket #423

I am using rostest under rosbuild to create unittests with Python.

I understand how to create unittests and rostests, for instance, to create a TestsCase and call it from rostest.rosrun:

import unittest
class MyFirstTestCase(unittest.TestCase):
    def setUp(self):
        # SetUp code

    def tearDown(self):
        # TearDown code

    def test_something(self):
        # some test code

    def test_more_stuff(self):
        # more test code


if __name__ == '__main__':
    import rostest
    rostest.rosrun('my_package', 'test_my_first_test_case', MyFirstTestCase)

However, I you want to create more TestCases it is good idea to add them to a TestSuite. For instance something like this:

import unittest
class MyFirstTestCase(unittest.TestCase):
    # ...

class AnotherTestCase(unittest.TestCase):
    def setUp(self):
        # SetUp code

    def tearDown(self):
        # TearDown code

    def test_another_thing(self):
        # some test code

    def test_yet_another_thing(self):
        # more test code


if __name__ == '__main__':

    def suite():
        suite = unittest.TestSuite()
        suite.addTest(MyFirstTestCase('test_something'))
        suite.addTest(AnotherTestCase('test_another_thing'))
        return suite

    my_suite = suite()
    import rostest
    rostest.rosrun('my_package', 'test_my_first_test_suite', my_suite)

Note that the call to rostest.rosrun uses a unittest.TestSuite as argument rather than a unittest.TestCase.

But it seems that rostest.rosrun is not compatible with unittest.TestSuite, since after runing this code you would get a TypeError like the following:

rostest.rosrun('my_package','test_my_first_test_case', my_suite)
File "/opt/ros/groovy/lib/python2.7/dist-packages/rostest/__init__.py", line 136, in rosrun suite = unittest.TestLoader().loadTestsFromTestCase(test) File "/usr/lib/python2.7/unittest/loader.py", line 50, in loadTestsFromTestCase if issubclass(testCaseClass, suite.TestSuite): TypeError: issubclass() arg 1 must be a class

After reading the documentation and looking for some examples I did not found any way to call a TestSuite from rostest. Is it any way to properly create a TestSuite under rostest?

Some partial solution would be calling the different TestCases in different calls to rostest.rosrun like that:

rostest.rosrun('my_package', 'test_my_first_test_case', MyFirstTestCase)
rostest.rosrun('my_package', 'test_another_test_case', AnotherTestCase)

But, somehow, rostest only outputs the results for the second call to rostest.rosrun unless --text is passed (see this question). This is not desirable since --text is more verbose and increases testing time. Moreover, I believe using a TestSuite would be much more flexible than manully adding calls to rostest.rosrun.

EDIT: I edited the title to make the question clearer.
