You should first get the repository upload token from codecov

Add the following to your .github/workflows/test.yml file.

name: Test workflow on: [push, pull_request] jobs: build: runs-on: ubuntu-latest name: Test scala steps: - uses: actions/checkout@v4 - uses: actions/setup-java@v4 with: distribution: 'adopt' java-version: '21' - name: Run tests run: sbt coverage test coverageReport - uses: codecov/codecov-action@v4 with: fail_ci_if_error: true token: ${{ secrets.CODECOV_TOKEN }}

Here we frist checkout the code, then setup java, run the tests and generate the coverage report. Finally, we upload the report to codecov using the codecov-action.

When all finished, you could also add a badge on readme like following.
