Correct! If you name all your test methods 'testXXX' (or 'test_XXX' if
you prefer) then they can be found automatically. The easiest way to
accomplish this is to add the following at the bottom of the module
containing your tests:

   if __name__ == '__main__':

This finds and runs all the test cases in the current module.

If you want to create a TestSuite comprising all the possible test methods
of a TestCase subclass, use a TestLoader. The simplest way is:

   mysuite = unittest.defaultTestLoader.loadTestsFromTestCase(MyTestCase)

or for all the tests in a module:

   mysuite = unittest.defaultTestLoader.loadTestsFromModule(mytestmodule)

Because if you keep test methods short and independent, and do the above to
find and run them, it's simpler, and non-fatal test failures aren't required.
