一个pytest插件，它将输出限制为您需要的东西。
pytest-tldr的Python项目详细描述
一个pytest插件，它将pytest的输出限制为 需要看看。
我个人对pytest最大的抱怨之一就是它的控制台 输出非常，非常健谈。它告诉你它开始了。它告诉你 工作。它告诉你一切都结束了。如果测试失败，不仅仅是 告诉你哪项考试不及格。它将一页又一页的代码转储到 你的控制台。
它用华丽的彩色来完成这一切。希望你有完美的 彩色视觉，你的控制台颜色选择是对比度兼容。
是的：pytest有很多很多命令行选项。其中一些行为 可以使用功能标志配置或关闭。但是有些人 （至少，假设是pytest核心团队）谁喜欢pytest的 输出格式。所以如果你是团队中唯一一个不喜欢 pytest的输出，不能将“更好的”选项提交到默认值中 配置-每次运行时都必须手动指定选项 测试套件。
幸运的是，pytest还有一个插件系统，所以我们可以解决这个问题。
pytest tldr是一个插件，它提供单色的最低限度输出， 同时仍然给出测试套件进度的指示。
安装
您可以通过PyPI中的pip安装“pytest tldr”：
$ pip install pytest-tldr
然后您可以正常运行测试套件：
$ pytest tests
