启用覆盖率后如何在PyCharm中调试py.test

问题描述

启用覆盖时如何在PyCharm中调试py.test？

使用-cov = project --cov启用覆盖-report = term-missing ，删除该行并击中断点。

版本：pycharm 5.0.3，pytest == 2.8.5， pytest-cache == 1.0，pytest-cov == 2.2.0，pytest-pep8 == 1.0.6，pytest-xdist == 1.13.1，python-coveralls == 2.6.0。

解决方案

现在有一个

额外提示：您可能还希望在其中添加 -s 标志，以便py.test不会吞噬输出。有关详细信息，请参见。

如果收到无法识别的参数错误，则可能需要安装 pytest-cov ，例如通过 pip安装pytest-cov 。

How do I debug py.test in PyCharm when coverage is enabled?

Coverage is enabled using --cov=project --cov-report=term-missing, removing this and breakpoints are hit.

Versions: pycharm 5.0.3, pytest==2.8.5, pytest-cache==1.0, pytest-cov==2.2.0, pytest-pep8==1.0.6, pytest-xdist==1.13.1, python-coveralls==2.6.0.

解决方案

There is now a flag in py.test to disable coverage which you can activate when running tests from PyCharm.

The flag to use is --no-cov. If you want this to apply to all your test runs you can add this to the default pytest configuration as below:

Extra tip: You probably also want a -s flag in there so output isn't swallowed by py.test. See https://stackoverflow.com/a/17810324/238166 for details.

In case you receive an "unrecognized argument" error, you may need to install pytest-cov, e.g. by pip install pytest-cov.
