Tools (8)

Read from the source code; the running server may differ. Descriptions are the server’s own words; hidden characters are shown as [U+…].

  • cluster_semantic_error_trees

    Groups test failures by semantic error similarity rather than raw string prefix. Strips dynamic values (UUIDs, numeric IDs, hashes, timestamps, URLs) via regex, then applies Levenshtein fuzzy matching to merge errors that differ only in minor dynamic fragments. Classifies each cluster by taxonomy (TimeoutError, AssertionError, NetworkError, ReferenceError). Use instead of get_error_groups when failure messages contain dynamic IDs or selector attributes that make identical root causes look different.

  • correlate_git_commit_flakiness

    Finds the exact point where a test transitioned from stable to flaky (or back), and returns the git commit SHA, branch, and author at that transition. Requires the Playwright reporter to be running in a CI environment where GITHUB_SHA / CI_COMMIT_SHA / CIRCLE_SHA1 env vars are set. Use to answer: which commit broke this test, and who authored it?

  • get_error_groups

    Groups failing tests by similar error messages to surface systemic failures. Use to answer: are 10 tests failing because of the same broken endpoint or shared root cause?

  • get_failure_patterns

    Breaks down failure rates by browser and OS combination. Use to answer: does this test only fail on Firefox? Only on Windows?

  • get_flakiness_trend

    Returns the daily flakiness rate for a specific test over the last N days. Use to answer: is this test getting worse, better, or staying the same?

  • get_flaky_tests

    Returns tests ranked by flakiness rate (failed+flaky / total runs). Use to answer: which tests are the most unreliable?

  • get_slow_tests

    Returns tests ranked by average duration. Use to answer: which tests are slowing down the CI pipeline?

  • get_test_history

    Returns the run history for a specific test — status, duration, error, retry count, browser, and OS for each run. Use to answer: is this test getting worse over time?
