Introducing Test Suite Size, a new analytics view that helps you track how your test suite evolves over time. Whether you're expanding coverage, refactoring tests, or debugging unexpected changes, this view gives you complete visibility into your test suite's composition.

• Track unique test cases and spec files discovered across all CI runs

• See exactly when and what tests were added or removed from your suite

• Monitor test growth by branch, tag, or team with flexible grouping

• Use rolling presence mode to smooth daily fluctuations from partial runs

• Drill down into any period to see the specific tests that changed

• Available now for all customers

Unlike run-level metrics that show tests per individual execution, Suite Size aggregates unique tests across all runs in each period. This means you get an accurate picture of your actual test coverage—not just what ran in a single CI job.

The expandable metrics table lets you click into any time period and see exactly which tests were newly detected or no longer running. Combined with grouping by Playwright tags, Git branches, or test groups, you can track coverage evolution across different parts of your codebase.

For teams with tests that don't run every day (scheduled tests, branch-specific tests, or selective execution), the Rolling Presence mode provides a stable view by counting tests seen within a configurable window—helping you distinguish real changes from normal variance.
