e2e-status for branch protection

[piotr-iohk]

Description

Adds an e2e-status job that aggregates the results of all E2E test shards.
This job provides a single unified status check (e2e-status) that can be used in branch protection rules to ensure all E2E shards pass before merging.

PR Review - E2E Status Job for Branch Protection

Overview

This PR adds a unified e2e-status job that aggregates results from all E2E test shards, providing a single status check for branch protection rules. This is a common and valuable pattern for workflows with matrix strategies.

Code Quality ✅

Strengths:

• Clean, focused implementation that follows GitHub Actions best practices
• Proper use of needs dependency to wait for all E2E shards
• Correct use of if: always() to ensure the status job runs even if E2E tests fail
• Clear, descriptive job and step names that match the workflow style
• Appropriate use of emoji indicators in output messages

Consistency with Repository:

• Follows the same naming conventions as other jobs in the workflow (.github/workflows/e2e.yml:210-221)
• Consistent with the workflow's existing structure and style

Potential Issues ⚠️

Minor Issue - Missing Newline at EOF:

• Line 221 is missing a newline at the end of the file
• This is a common best practice and convention for text files
• Recommendation: Add a newline after the final echo statement

Best Practices 🔍

Architecture Pattern:
The implementation correctly follows the "status check aggregation" pattern used in many CI/CD workflows. The key elements are properly implemented:

1. ✅ needs: [e2e-tests] - waits for the matrix job
2. ✅ if: always() - runs regardless of previous job outcomes
3. ✅ Explicit failure exit (exit 1) when tests fail

Alternative Consideration:
While the current implementation is good, you could also consider checking for specific outcomes beyond just "success":

if: ${{ needs.e2e-tests.result != 'success' && needs.e2e-tests.result != 'cancelled' }}

This would distinguish between failures and cancellations, though the current approach is simpler and likely sufficient.

Performance Considerations ✅

• Negligible performance impact - this is a lightweight status aggregation job
• Runs on ubuntu-latest which is appropriate for this simple bash script
• No unnecessary dependencies or actions

Security Concerns ✅

• No security concerns identified
• No secrets or sensitive data handling
• Simple bash script with no external inputs
• Read-only operation checking job status

Test Coverage 📝

Testing Notes:
Since this is a workflow configuration change:

• The change can be validated by observing the workflow run in the Actions tab
• Verify that the e2e-status job appears as a unified check in the PR
• Confirm that branch protection rules can use e2e-status as a required check

Suggested QA:

1. Run the workflow with all shards passing → e2e-status should succeed
2. Run the workflow with at least one shard failing → e2e-status should fail
3. Verify the job appears correctly in GitHub's status checks UI
4. Test that branch protection rules recognize and enforce the new status check

Summary

This is a well-implemented and valuable addition to the CI/CD workflow. The code is clean, follows best practices, and will improve the developer experience by providing a single unified status check for branch protection.

Recommendation: APPROVE ✅ (with the minor newline fix as optional polish)

---

Action Items:

• Optional: Add newline at end of file (.github/workflows/e2e.yml:221)
• Verify the status check appears correctly in PR UI after merge
• Update branch protection rules to use e2e-status instead of individual shard checks

Pull Request Overview

This PR adds an aggregation job e2e-status to the E2E workflow that provides a single unified status check for branch protection rules. This ensures all E2E test shards must pass before merging.

• Adds a new e2e-status job that depends on the e2e-tests matrix job
• Implements conditional logic to check if all E2E test shards succeeded
• Provides clear success/failure messages with emoji indicators

PR Review: e2e-status for branch protection

Summary

This PR adds an aggregator job (e2e-status) to provide a unified status check for all E2E test shards, enabling simplified branch protection rules. The implementation is clean and follows GitHub Actions best practices.

---

✅ Strengths

1. Clear Purpose: The single unified status check simplifies branch protection configuration
2. Proper Dependencies: Correctly uses needs: [e2e-tests] to ensure all shards complete
3. Always Runs: The if: always() condition ensures the status job runs even when upstream jobs fail
4. Appropriate Error Handling: Checks the result status and exits with proper codes

---

📋 Code Quality Assessment

Overall: Good ✓

The code follows GitHub Actions conventions and is straightforward:

• Clear job naming
• Appropriate use of conditional execution
• Simple, readable bash script
• Proper exit codes (0 for success, 1 for failure)

---

🐛 Potential Issues

Minor: Missing Newline at EOF

.github/workflows/e2e.yml:221 - The file is missing a newline at the end

• Impact: Low (cosmetic, but some tools/editors flag this)
• Fix: Add a newline after the last line

Consideration: Handling Skipped Jobs

The current implementation only checks for success status, but does not explicitly handle other possible outcomes:

• success ✓
• failure ✓ (implicitly handled)
• cancelled (not explicitly handled)
• skipped (e.g., if the build or e2e-branch jobs fail)

The e2e-tests job can be skipped if github.event.pull_request.draft == false evaluates to false. In this case, the e2e-status job would currently fail because needs.e2e-tests.result would be skipped, not success.

Recommendation: Consider whether skipped E2E tests should pass or fail the status check. If draft PRs should pass the status check, you might want to handle the skipped state explicitly.

---

⚡ Performance Considerations

No concerns - The job is extremely lightweight:

• Single Ubuntu runner
• Only bash commands
• Negligible resource usage
• No additional latency to the workflow

---

🔒 Security Concerns

No concerns - The job:

• Uses only built-in GitHub Actions expressions
• No external dependencies
• No secret handling
• No user input processing
• Read-only operations

---

🧪 Test Coverage

Manual Testing Needed:

1. ✓ Verify status check appears in PR checks
2. ✓ Confirm it passes when all shards succeed
3. ✓ Confirm it fails when any shard fails
4. ✓ Test with draft PRs (to verify skipped behavior)
5. ✓ Test branch protection rules integration

Since this is workflow infrastructure, there is no unit test coverage needed, but you should verify the workflow behavior in practice.

---

💡 Suggestions

1. Add Newline at EOF: For consistency with standard file formatting
2. Consider Skipped State: Decide how to handle skipped E2E tests (draft PRs)
3. Documentation: Consider adding a comment in the workflow explaining why this job exists (for future maintainers)

---

✅ Recommendation

Approve with minor suggestions

The PR achieves its goal effectively. The only required change is adding a newline at EOF. The skipped state handling is worth considering but may not be necessary depending on your branch protection strategy.

Once merged, remember to:

1. Update branch protection rules to require the e2e-status check
2. Remove individual shard checks from branch protection (if desired)

Great work on improving the CI/CD workflow! 🚀
