The lcov-action can be leverage to easily integrated codecov and their action into any CI pipeline.

When running lcov-action with the default working directory and coverage output file, the coverage.info will be created in ${{github.workspace}}, so the only step required is to pass the full path to the codecov action using files: ${{github.workspace}}/coverage.info.

Here an example taken from cachegrand main CI workflow ( https://github.com/danielealbano/cachegrand/blob/main/.github/workflows/build_and_test.yml )

- name: Tests - Unit Tests
  working-directory: ${{github.workspace}}/build
  shell: bash
  run: cd tests/unit_tests && sudo ./cachegrand-tests --order lex

- name: Code Coverage - Generation
  uses: danielealbano/[email protected]
  with:
    gcov_path: /usr/bin/gcov-9
    remove_patterns: 3rdparty,tests

- uses: codecov/codecov-action@v3
  with:
    files: ${{github.workspace}}/coverage.info
    flags: unittests # optional
    name: cachegrand-server
