Teamcity消息单元测试看不到Python 2中的测试

Question

我有一个具有以下结构的项目

​

​

test_scripts.py由单个unittest.TestCase类组成，并以以下代码结束。

if __name__ == '__main__':
    try:
        from teamcity import is_running_under_teamcity
        from teamcity.unittestpy import TeamcityTestRunner
        if is_running_under_teamcity():
            runner = TeamcityTestRunner()
        else:
            runner = unittest.TextTestRunner()
    except ModuleNotFoundError:
        runner = unittest.TextTestRunner()
    unittest.main(testRunner=runner)

因此，当我尝试用python3 python3 -m teamcity.unittestpy运行它时，我得到

... some tests output
##teamcity[testFinished timestamp='2019-11-14T14:08:24.591' duration='0' flowId='tests.test_scripts.Test.test_sub' name='tests.test_scripts.Test.test_sub']


Ran 7 tests in 0.004s

OK

但是当我用Python2做同样的事情时

python -m teamcity.unittestpy
##teamcity[testCount timestamp='2019-11-14T14:09:16.392' count='0']


Ran 0 tests in 0.000s

OK

我100%确定python解释器上安装了teamcity-messages。为什么它看不到测试？

Answer 1

在Python2中，它只能与python -m teamcity.unittestpy discover调用一起使用。此调用也适用于Python 3。
