python - 如何使用 nose2 从给定的包中获取覆盖率报告

Question

我想将 nose2 与覆盖率插件一起使用来获得 Python 包的覆盖率，但我很难将其配置为仅覆盖我正在处理的包。该包名为 vimhdl，我的 unittest.cfg 的覆盖部分如下所示:

[coverage]
coverage = vimhdl

对于 nose2，结果不包括包中的所有文件(可能是因为 Coverage.py warning: Module vimhdl was previously imported, but not measured.消息，但我不知道如何修复它)。

此外，当打开给定文件的 HTML 报告时，import logging 和模块的文档字符串等语句被标记为未涵盖。

$ nose2 --with-coverage   -vvv
...

Ran 5 tests in 0.166s

OK
Coverage.py warning: Module vimhdl was previously imported, but not measured.

另一方面，使用nosetests，结果包括预期的所有文件。

$ nosetests --with-coverage -vvv

如何配置 nose2 覆盖插件以仅覆盖给定模块？

如果有帮助，源代码在 https://github.com/suoto/vim-hdl/tree/unstable 的 github 上。

控制 coverage.py 的最简单方法是使用它来运行测试:

coverage run --source=vimhdl -m nose
