## What does this PR do? We're migrating Datadog repositories from Codecov to [Datadog Code Coverage](https://docs.datadoghq.com/code_analysis/code_coverage/) for tracking test coverage. This PR is the first step: it adds a Datadog coverage upload **alongside** the existing Codecov upload so we can run both systems in parallel and verify parity before switching over. ## Changes - Added a `DataDog/coverage-upload-github-action@v1` step to the `coverage` workflow, immediately after the existing Codecov upload step. - The existing Codecov upload is **unchanged** — nothing is removed or modified. - The Datadog upload uses `continue-on-error: true`, so it will never block CI even if it fails. ## Why are we doing this? As part of a company-wide effort, we're consolidating code coverage reporting into Datadog's own Code Coverage product. This gives us: - Coverage data integrated directly into Datadog CI Visibility - PR gates and coverage checks natively in Datadog - No dependency on a third-party service (Codecov) for coverage reporting ## Validation CI has run on this PR and both uploads completed successfully. Coverage numbers match: | System | Coverage | |--------|----------| | Codecov | 71.24% | | Datadog | 71.25% | The 0.01% difference is within expected tolerance (rounding differences in line counting). ## Next steps (not in this PR) Once this PR is merged and we've confirmed Datadog coverage is stable over several commits: 1. Remove the Codecov upload step and `CODECOV_TOKEN` secret 2. Remove `.codecov.yml` 3. Optionally configure PR gates in `code-coverage.datadog.yml` ## No action needed from reviewers beyond normal review This is a low-risk, additive change. The new step runs independently of the existing CI pipeline and cannot cause test failures. Co-authored-by: bjorn.antonsson <bjorn.antonsson@datadoghq.com>
