python - Django + django-nose 的 PyCharm 代码覆盖率

Question

当尝试在 PyCharm 中的 Django + django-nose 下运行覆盖率测试时，我似乎无法让覆盖率报告正常工作。我试过使用捆绑的 coverage.py 和不使用。没有捆绑的 coverage.py 我看到:

Traceback (most recent call last):
  File "/Applications/PyCharm.app/Contents/helpers/coverage_runner/run_coverage.py", line 44, in <module>
    main()
  File "/Users/dane/.virtualenvs/dhp/lib/python3.5/site-packages/coverage/cmdline.py", line 741, in main
    status = CoverageScript().command_line(argv)
  File "/Users/dane/.virtualenvs/dhp/lib/python3.5/site-packages/coverage/cmdline.py", line 481, in command_line
    return self.do_run(options, args)
  File "/Users/dane/.virtualenvs/dhp/lib/python3.5/site-packages/coverage/cmdline.py", line 625, in do_run
    self.coverage.stop()
  File "/Users/dane/.virtualenvs/dhp/lib/python3.5/site-packages/coverage/control.py", line 692, in stop
    self.collector.stop()
  File "/Users/dane/.virtualenvs/dhp/lib/python3.5/site-packages/coverage/collector.py", line 277, in stop
    "Expected current collector to be %r, but it's %r" % (self, self._collectors[-1])
AssertionError: Expected current collector to be <Collector at 0x10e0cfbe0: CTracer>, but it's <Collector at 0x10fa368d0: CTracer>

有了它，我看到了:

Traceback (most recent call last):
  File "/Applications/PyCharm.app/Contents/helpers/coverage_runner/run_coverage.py", line 44, in <module>
    main()
  File "/Applications/PyCharm.app/Contents/helpers/coveragepy/coverage/cmdline.py", line 721, in main
    status = CoverageScript().command_line(argv)
  File "/Applications/PyCharm.app/Contents/helpers/coveragepy/coverage/cmdline.py", line 438, in command_line
    self.do_execute(options, args)
  File "/Applications/PyCharm.app/Contents/helpers/coveragepy/coverage/cmdline.py", line 580, in do_execute
    self.coverage.stop()
  File "/Applications/PyCharm.app/Contents/helpers/coveragepy/coverage/control.py", line 410, in stop
    self.collector.stop()
  File "/Applications/PyCharm.app/Contents/helpers/coveragepy/coverage/collector.py", line 294, in stop
    assert self._collectors[-1] is self
AssertionError

我的测试和覆盖率报告通过命令行正常工作，即:

$ python manage.py test

我已经使用 Django 测试模板设置了一个运行配置，据我所知，我没有做任何特别或不寻常的事情。有没有人遇到这个并解决了它？覆盖整合将非常有用!

Answer 1

我假设您的配置中有类似的东西:

NOSE_ARGS = [
    '--with-coverage',
    '--cover-package=foo,bar'
]

PyCharm 的覆盖范围在配置时会爆炸。我假设它正在运行两个覆盖实例，或者覆盖输出不是它预期解析的内容。无论哪种方式，您目前似乎都无法使用它。

目前的解决方案:

• 删除 NOSE_ARGS 配置，如果您的任何自动化/持续集成工具需要它，请在命令行上使用覆盖选项运行它们:python manage.py test --with- coverage --cover-package=foo(我选择这个选项是因为 PyCharm 的好处)
• 不要在 PyCharm 中使用覆盖
