vprof interfere with unittest autodiscovery

[xcombelle]

With this code:

import unittest

class MyTest(unittest.TestCase):
    def test_fail(self):
        self.assertTrue(False)

unittest.main()

I get the following result

xcombelle@ender ~/d/sgftool> vprof -c cmh  -s test.py  --port 8080

Both execution should have the same result

This is interesting. It seems that it's because unittest does some magic to do autodiscovery. I'll take a look.

[nvdv]

It happens because unittest discovery tries to load tests from __main__ module by default. When module is run under vprof, __main__ points to vprof module, which does not have any tests and that's why line Ran 0 tests in 0.000s is displayed. I can suggest to specify module explicitly unittest.main(module=...) if you need to run it under vprof.

That sounds logical thanks for watching

Facing similar issue. Explicitly specifying the module too not working for me.

Works for me when I save this code to example_test.py:

import unittest

class MyTest(unittest.TestCase):
    def test_fail(self):
        self.assertTrue(False)

unittest.main(module='example_test')

and run it.
