如果测试没有足够的Python覆盖率，如何使travis失败
问题描述：
如果我的测试覆盖范围不足，我可能会导致travis失败，例如<例如90％。
I it possible to have travis fail if my test don't have enough coverage, say < 90% for example.
通常，我使用以下travis配置条目运行测试。
Normally I run my tests with the following travis config entry.
script:
- coverage run --source="mytestmodule" setup.py test

根据此链接，如果您将-fail-under 开关添加到覆盖范围报告命令，如果代码覆盖率低于给定的百分比，它将以非零退出代码退出（travis将视为失败）。
According to this link, if you add the --fail-under switch to the coverage report command, it will exit with a non-zero exit code (which travis will see as a failure) if the code coverage is below the given percentage.
这将使 .travis.yml 文件的脚本部分看起来像：
That would make the script section of your .travis.yml file look like:
script
- coverage run --source="mytestmodule" setup.py test
- coverage report --fail-under=80
当然，您可以用任意百分比替换80。
Of course you could replace 80 with whatever percentage you'd like.
