Test Failure Details in PR Comments

We’ve expanded the information included in PR comments from CI Insights.

Previously, comments only reported job-level results (success, failure, retries).

Now, they also include test-level insights:

• Failed tests are listed directly in the PR comment.
• Flaky tests are highlighted with their recent history.
• Linked details let you jump into CI Insights for deeper investigation.

This makes it easier for developers and reviewers to see exactly which tests failed without digging into raw CI logs — saving time and reducing context switching.
