从 PyCharm 内部使用 pytest-cov 插件
[英]Using pytest-cov plugin from inside PyCharm
问题描述
I want to use pytest and pytest-cov plugin from inside PyCharm, so I added --cov=package to "Additional arguments" entry field when I edited my configuration.
我想从 PyCharm 内部使用 pytest 和 pytest-cov 插件，因此我在编辑配置时将--cov=package添加到“附加参数”输入字段。 However, I get both the output and the error, not sure why:但是，我得到了输出和错误，不知道为什么：

That's because PyCharm's test plugin didn't adapt to breaking changes in coverage>=5.0 yet.这是因为 PyCharm 的测试插件还没有适应coverage>=5.0重大变化。 Here's a related issue in JetBrain's tracker: PY-40980 .这是 JetBrain 跟踪器中的一个相关问题： PY-40980 。 Until the issue is fixed, pin coverage to previous major:在问题解决之前，将coverage固定到以前的专业：
$ pip install 'coverage<5'
