    # 2. which in turn calls self.createTests().
    # 3. then the constructor calls self.runTests().

    # of self.testLoader's "loadTests" methods.  Each loadTest method returns
    # a unittest.TestSuite instance.  Thus, self.test is set to a TestSuite
    # instance prior to calling runTests().
