How to know time spent on each test when using unittest?

Question

Unittest presents only total time spent on running all tests but does not present time spent on each test separately.

How to add timing of each test when using unittest?

Answer 1

I suppose, that it's not possible for now: http://bugs.python.org/issue4080.

But you can do something like this:

import unittest
import time

class SomeTest(unittest.TestCase):
    def setUp(self):
        self.startTime = time.time()

    def tearDown(self):
        t = time.time() - self.startTime
        print('%s: %.3f' % (self.id(), t))

    def testOne(self):
        time.sleep(1)
        self.assertEqual(int('42'), 42)

    def testTwo(self):
        time.sleep(2)
        self.assertEqual(str(42), '42')

if __name__ == '__main__':
    suite = unittest.TestLoader().loadTestsFromTestCase(SomeTest)
    unittest.TextTestRunner(verbosity=0).run(suite)

Result:

__main__.SomeTest.testOne: 1.001
__main__.SomeTest.testTwo: 2.002

Ran 2 tests in 3.003s

OK
