如何使用nose2从给定的包中获取覆盖率报告

标签: python nose coverage.py nose2

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'等语句。 doc字符串标记为未涵盖。

$ 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 ,结果包括所有预期的文件。

$ nosetests --with-coverage -vvv

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
