Pydevcodecoverage结果不会出现-Pydevcodecoverageresultsdon'tappear

I just had the same problem and the solution was to install coverage from 3.x branch (i.e. pip install "coverage <4.0.0").

我只是遇到了同样的问题,解决方案是从3.x分支安装覆盖(即pip install“coverage <4.0.0”)。

There's a hint on PyDev coverage documentation page:

有关PyDev覆盖文档页面的提示:

... the integration is tested with version 3.4, so, this is the recommended version.

...使用3.4版测试集成,因此,这是推荐的版本。

Coverage v4 has default report file name and its format changed. Older file name was ~/.metadata/.plugins/org.python.pydev.debug/coverage/.coverage and it contained binary marshal'ed output (according to this answer). Newer is in ~/.metadata/.plugins/org.python.pydev.debug/coverage/.coverage.0 and it contains JSON string prefixed with !coverage.py: This is a private format, don't read it directly! ;-)

覆盖范围v4具有默认报告文件名,其格式已更改。较旧的文件名是〜/ .metadata / .plugins / org.python.pydev.debug / coverage / .coverage,它包含二进制编组输出(根据此答案)。较新的是〜/ .metadata / .plugins / org.python.pydev.debug / coverage / .coverage.0,它包含前缀为!coverage.py的JSON字符串:这是私有格式,请勿直接读取! ;-)
