我有一个项目可以随意使用 C++ 测试覆盖率。（https://github.com/adomasbaliuka/test_repository，问题指的是提交 58e2802f76e8eb7819209c9d518b0ffe76690d15 和 ca36a4fd0e38bc47204a155614c498936d43dc90）
这个问题涉及 GitHub 和 Codecov.io，所以也许我应该请求他们的支持，但是 StackOverflor 有这些东西的标签，所以我认为没关系。
codecov.io 的覆盖范围正在发挥作用( https://app.codecov.io/gh/adomasbaliuka/test_repository )。但是，我想看看实际的源代码和行覆盖率来测试 codecov.io 的这个特性。它在我test/test_main.cpp的一个文件（我的 CI 运行，因此它们也可以在 GitHub Actions 中查看）在概念上看起来完全相同：src/version/version.cppcodecov.xml
（codecov.xml文件内容：

特别是其中文件的路径xml是test_repository/tests/test_main.cpp和test_repository/src/version/version.cpp。我完全不明白 codecov.io 可能在那里看到的问题或差异。
在 codecov.io 中，单击文件src/version/version.cpp会给我一个错误
GitHub API：未找到
我尝试按照 codecov.io 的建议进行一些“路径修复”，这意味着包括一个顶级文件codecov.yml。我把这个文件里面
fixes:
- "test_repository/::"
我假设用路径中的“无”替换存储库的名称。结果是第一个文件仍然有效，而第二个文件的错误消息变为
好吧，这很尴尬，看起来我们有一个错误。
我不依赖于在我的所有文件上使用此功能，但是这种行为（文件之间的差异）对我来说很奇怪。有任何想法吗？
