unittest breaks "fastfail" (and probably other) options

import unittest
from unittest import TestCase

from teamcity.unittestpy import TeamcityTestRunner

    def test_1_test(self):

    unittest.main(testRunner=runner)

It says 2 tests (third one skipped)

[shalupov]

for Python 3.2 (where all additional options are supported) you need to call unittest.main differently:

    main(argv=args, module=None, buffer=True, testRunner=unittestpy.TeamcityTestRunner)

this way all custom options like failfast will be passed to TextTestRunner which will handle it

@shalupov thats exactly what I am doing.

[shalupov]

@throwable-one you're making an instance of TeamcityTestRunner by youself. If you pass type instead of instance unittest will create it itself and pass all relevant arguments (i.e. buffer and failfast)

@shalupov Got it, thank you!

btw, should not you fix your example code then: https://github.com/JetBrains/teamcity-messages ?
