A repo to test how to report coverage of a C++ project using Github Actions, using https://codecov.io.

See:

* Example PRs [increasing](https://github.com/jmarrec/TestCpp-GHA-Coverage/pull/1) and [decreasing](https://github.com/jmarrec/TestCpp-GHA-Coverage/pull/2) coverage

* the Github Actions workflow at [.github/workflows/build.yml](.github/workflows/build.yml)

----

## Additional

Additionally, it includes a [cppcheck action](.github/workflows/cppcheck.yml) with a custom python script ([ci/colorize_cppcheck_results.py](./ci/colorize_cppcheck_results.py)) I created that will print a summary of offenses and add color to your action.

There is also a [clang-format action](.github/workflows/clang-format-check.yml) that uses the `.clang-format` file in the repo.

(Note: A `.clang-tidy` file is also provided, but I didn't bother adding an action for that.)

## Multi platform support

`Person.cpp` has a few compiler specific macros, so that we can test merging reports from several platforms on codecov. See [src/Person.cpp#L18-L27](https://github.com/jmarrec/TestCpp-GHA-Coverage/blob/408d98bb68b05222006d052dd6367090827ed8fc/src/Person.cpp#L18-L27)

See [PR#5](https://github.com/jmarrec/TestCpp-GHA-Coverage/pull/5) for more info including before/after screenshots when I added Mac in addition to Ubuntu

See [PR#6](https://github.com/jmarrec/TestCpp-GHA-Coverage/pull/6) when I added Windows (via OpenCppCoverage) in addition to Mac and Ubuntu. **Looks like Windows's report don't merge correctly to codecov?**

**Note: Looks like there is a viewing problem where the clang line is no longer green, yet report is correctly at 100%**
