我想使用nose2和coverage插件来获取Python包的覆盖范围，但是我很难配置它以仅覆盖我正在处理的包。该包名为vimhdl，我的unittest.cfg的覆盖范围部分如下所示：
[coverage]
coverage = vimhdl
使用 nose2 ，结果不包含包中的所有文件（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，在打开给定文件的HTML报告时，会出现import logging和模块＆＃39;等语句。 doc字符串标记为未涵盖。
$ nose2 --with-coverage -vvv
...

如何配置nose2覆盖率插件以仅覆盖给定模块？

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
