Question

How do I run multiple Classes in a single test suite in Python using unit testing?

Answer 1

Normally you would do in the following way (which adds only one class per suite):

# Add tests.
alltests = unittest.TestSuite()
alltests.addTest(unittest.makeSuite(Test1))
alltests.addTest(unittest.makeSuite(Test2))

If you'd like to have multiple classes per suite, you can use add these tests in the following way:

for name in testnames:
    suite.addTest(tc_class(name, cargs=args))

Here is same example to run all classes per separate suite you can define your own make_suite method:

# Credits: http://codereview.stackexchange.com/a/88662/15346
def make_suite(tc_class):
    testloader = unittest.TestLoader()
    testnames = testloader.getTestCaseNames(tc_class)
    suite = unittest.TestSuite()
    for name in testnames:
        suite.addTest(tc_class(name, cargs=args))
    return suite

# Add all tests.
alltests = unittest.TestSuite()
for name, obj in inspect.getmembers(sys.modules[__name__]):
    if inspect.isclass(obj) and name.startswith("FooTest"):
        alltests.addTest(make_suite(obj))

result = unittest.TextTestRunner(verbosity=2).run(alltests)

If above doesn't suite, you can convert above example into method which could accept multiple classes.
