Question

I am trying to code a suite test, I have one module which runs unit test correctly but I intend to add more modules and test them at once, so I have coded the following code:

#main.py

import unittest
from test.Services import TestOS

if __name__ == '__main__':
    suite = unittest.TestSuite()
    suite.addTests( TestOS.TestOS() )
    unittest.TextTestRunner().run(suite)

TestOS.py

import unittest
from app.Services.OS import OS

class TestOS(unittest.TestCase):
    os = OS()
    def setUp(self):
        pass
    def tearDown(self):
        pass
    def testOSName(self):
        self.assertEquals(self.os.getPlatform(), 'Windows')    
    def testOSVersion(self):
        self.assertEquals(self.os.getVersion(), '7')

if __name__ == "__main__":
    #import sys;sys.argv = ['', 'Test.testName']
    unittest.main()

After running it, I get this output:

Finding files... done.
Importing test modules ... done.

Ran 0 tests in 0.000s

OK

It didn’t find any test, What’s wrong with my code?

Answer 1

suite.addTest( TestOS.TestOS() ) works only if your testcase contains a runTest() function.
Otherwise you need a “TestLoader” to detect the functions of TestOS that start with “test*”.

#main.py

import unittest
from test.Services import TestOS

if __name__ == '__main__':
    suite = unittest.TestSuite()
    tests = unittest.defaultTestLoader.loadTestsFromTestCase(TestOS)
    suite.addTests(tests)
    unittest.TextTestRunner().run(suite)
