31
32
33class SampleTestCase(unittest.TestCase):
34    """Dummy tests that sleep for demo."""
35
36    def test_me_1(self):
37        time.sleep(0.5)
38
39    def test_me_2(self):
40        time.sleep(0.5)

43        time.sleep(0.5)
44
45    def test_me_4(self):
46        time.sleep(0.5)

48
49# Load tests from SampleTestCase defined above
50suite = unittest.TestLoader().loadTestsFromTestCase(SampleTestCase)
51runner = unittest.TextTestRunner()
52
53# Run tests sequentially
54runner.run(suite)
55
56# Run same tests across 4 processes
57suite = unittest.TestLoader().loadTestsFromTestCase(SampleTestCase)
58concurrent_suite = ConcurrentTestSuite(suite, fork_for_tests(4))
59runner.run(concurrent_suite)
