Trunk Flaky Tests detects flaky tests by analyzing test results. The health of your tests is displayed in the Flaky Tests dashboard.
Press ⌘ K (macOS) or Ctrl K (Windows and Linux) anywhere in the Trunk app to open the command palette. Start typing to jump to Merge Queue, Flaky Tests, your account settings, or any connected repository by name.

​
Repositories overview

When you navigate to /<your-org>/flaky-tests, you land on a repositories overview showing all monitored repositories at a glance. Each repository row displays: A quarantine status icon appears next to each repository name when quarantining is configured: Active repositories (with test data in the last 30 days) appear at the top of the list. Repositories with no recent data are collapsed under an Inactive Repositories section that you can expand to view. Selecting a repository opens its detailed dashboard. If your organization has no repositories connected yet, the page redirects to onboarding. See Quarantining to learn how to configure quarantine settings.

Key repository metrics

Key repo metrics

Trunk Flaky Tests provides key repo metrics based on the detected health status of your tests. You’ll find metrics for the following information at the top of the Flaky Tests dashboard. These numbers are important for understanding the overall health of your repo’s tests, how flaky tests impact your developer productivity, and the developer hours saved from quarantining tests. You can also view the trends in these numbers in the trend charts. The trend charts display the New Test Cases added by day, as well as Test Transitions and Quarantined Runs. Test Transitions represent the number of tests that have transitioned to a particular status on a particular day, excluding new test cases (which default to a status of Healthy). If a bar shows 5 Healthy, 10 Flaky, and 2 Broken on a single day, that indicates 5 tests transitioned to Healthy, 10 to Flaky, and 2 to Broken on that day. Quarantined Runs represents the number of runs of quarantined tests by day.

​
Tests cases overview

You can view a table of all your test cases and their current status in Trunk Flaky Tests. Filters can also be set on the table to narrow test results down by test status, quarantine setting, ticket status, or by the name, file, or suite name of the test case. The table is sorted by default by the number of PRs impacted by the case, which is the best way to measure the impact of a flaky test. You can click on each test case to view the test case’s details.
Test Deletion & History
  • Inactive tests disappear from the dashboard automatically after 30 days and are fully removed after 45 days. Tests cannot be manually deleted.
  • Changing test identifiers (e.g., adding file paths) creates new test entries — merging with old history isn’t supported.

​
Test case details

You can click on any of the test cases listed on the Flaky Tests dashboard to access the test case’s details. The test details page uses a tabbed layout:
  • Summary: Run result charts and failure types grouped by unique failure reason.
  • Test History: A searchable, paginated table of every individual test run with filtering and a detail panel.
  • Monitors: Detection monitors configured for this test (visible when the detection engine is enabled).
  • Events: A timeline of detection events, quarantine actions, ticketing events, and status transitions (Healthy, Flaky, Broken) for this test (visible when the detection engine is enabled). Use the category filter to scope to Flake Detection events to see which monitor triggered each transition.
In addition to the tabbed content, the test details page shows the test’s current status (Healthy, Flaky, or Broken), ticket status, and codeowner information.

​
Code owners

If you have a codeowners file configured in your repos, you will see who owns each flaky test in the test details view. We support code owners for GitHub and GitLab repos.

You can find the code owners of each test on the top right of the test details screen.

This information will also be provided when creating a ticket with the Jira integration or webhooks.

​
Summary tab

The Summary tab shows an overview of the test’s recent run results and groups past failures by unique failure type.

​
Failure types

The Failure Types table shows the history of past test runs grouped by unique failure types. The Failure Type is a summary of the stack trace of the test run. You can click on the failure type to see a list of test runs labeled by branch, PR, Author, CI Job link, duration, and time.

​
Failure details

You can click on any of these test runs to see the detailed stack trace:
You can flip through the stack traces of similar failures across different test runs by clicking the left and right arrow buttons. You can also see other similar failures on this and other tests. Go to the CI job logs. If you want to see full logging of the original CI job for an individual test failure, you can click Logs in the expanded failure details panel to go to the job’s page in your CI provider.

​
Test History tab

The Test History tab gives you full visibility into every individual run of a test. Use it to investigate patterns across branches, find specific failing runs, and drill into error details.

​
Daily runs chart

A stacked bar chart at the top of the tab shows daily test run counts. The legend identifies four categories:
  • Green: Pass
  • Red: Fail
  • Blue: Quarantined
  • Gray: Skipped
Click and drag on the chart to select a date range, which scopes the table below to runs from the selected days. The selected range appears next to the legend with an X button to clear just the range. The Reset button on the filter bar clears all filters at once, including the date range. The Result and Quarantined filters from the filter bar also apply to the chart bars. When you filter to only passing runs, for example, the chart shows only green (Pass) bars. The chart and table always reflect the same set of runs.

​
Filters

A filter bar below the chart provides four independent controls: Branch filter examples: All filters combine using AND logic, so you can use them together. For example, set Result to Fail and Quarantined to Only to surface only quarantined failures. The Reset button clears every filter at once, including the chart date range. Filter state is saved in the URL, so you can share or bookmark a filtered view. The Result filter accepts result=pass or result=fail. The Quarantined filter accepts quarantined=include, quarantined=exclude, or quarantined=only.

​
Runs table

The runs table displays a paginated list of individual test runs (25 per page) with the following columns: Each row has a colored left border indicating the run’s outcome. Quarantined runs always show blue, regardless of whether the run passed or failed. For non-quarantined runs, the border is green for pass, red for fail, orange for error, and a neutral gray for any other state.

​
Run detail panel

Click any row in the runs table to open a detail panel on the right side of the page. The panel shows:
  • Run header: Timestamp, a result badge (Pass, Fail, Error, or Quarantined), and run duration.
  • Source control: A CI job link (with the provider’s icon, the job name, and the CI duration), the linked pull request, branch, and commit. Merge queue runs also include a View in Merge Queue link.
  • Error details: For failed, errored, or quarantined runs, an optional AI summary of the failure followed by the raw error text or stack trace.
