Unit test script returns exit code = 0 even if tests fail

Question

My testing script looks as follows:

import os
import sys
from unittest import defaultTestLoader as loader, TextTestRunner

path_to_my_project = os.path.dirnam         


        

Answer 1

I had some trouble getting TextTestRunner results. For those like me, here is how it works:

"""Run all tests inside of *_test.py modules located in the same directory."""


import sys
import unittest


if __name__ == '__main__':
    test_suite = unittest.defaultTestLoader.discover('.', '*_test.py')
    test_runner = unittest.TextTestRunner(resultclass=unittest.TextTestResult)
    result = test_runner.run(test_suite)
    sys.exit(not result.wasSuccessful())

Answer 2

The code is not using unittest.main. You need to check the result using TestResult.wasSuccessful and call sys.exit manually.

import sys

....

ret = not runner.run(suite).wasSuccessful()
sys.exit(ret)
