PyCharm and unittest won't run

Question

I have a problem with PyCharm 3.0.1 I can't run basic unittests.

Here is my code :

import unittest from MysqlServer import MysqlServer


class MysqlServerTest(unittest.TestCase):


    def setUp(self):
        self.mysqlServer = MysqlServer("ip", "username", "password", "db", port)


    def test_canConnect(self):
        self.mysqlServer.connect()
        self.fail()


if __name__ == '__main__':
    unittest.main()

Here is All the stuff PyCharm give me

Unable to attach test reporter to test framework or test framework quit unexpectedly

It also says

AttributeError: class TestLoader has no attribute '__init__'

And the event log :

2:14:28 PM Empty test suite

The problem is when I run manually the Python file (with PyCharm, as a script)

Ran 1 tests in 0.019s

FAILED (failures=1)

Which is normal I make the test fail on purpose. I am a bit clueless on what is going on. here more information :

• Setting->Python Integrated Tools->Package requirements file: <PROJECT_HOME>/src/test
• Default test runner: Unittests
• pyunit 1.4.1 Is installed

EDIT: Same thing happen with the basic usage from unitests.py

import unittest


class IntegerArithmenticTestCase(unittest.TestCase):
def testAdd(self):  ## test method names begin 'test*'
    self.assertEquals((1 + 2), 3)
    self.assertEquals(0 + 1, 1)

def testMultiply(self):
    self.assertEquals((0 * 10), 0)
    self.assertEquals((5 * 8), 40)


if __name__ == '__main__':
    unittest.main()

Answer 1

Although this wasn't the case with the original poster, I'd like to note that another thing that will cause this are test functions that don't begin with the word 'test.'

class TestSet(unittest.TestCase):      def test_will_work(self):         pass      def will_not_work(self):         pass 

Answer 2

This is probably because you did not set your testing framework correctly in the settings dialogue.

Answer 3

Definitely a pycharm thingy, repeating from above,

• Run --> Edit Configurations.
• select the instances of the test, and press the red minus button.

Answer 4

I have the exact same problem. It turned out that the fact of recognizing an individual test was related to the file name. In my case, test_calculate_kpi.py, which PyCharm didn't recognize as a test when renamed to test_calculate_kpis.py, was immediately recognized.
