v0.53.0
This release records per-test browser and server coverage and ranks the changed lines the failing tests executed as suspect lines, shows the page's live state in the DOM view, marks retried attempts on the run timeline, and adds a sample app that ASP.NET Core and Nitro both serve.
Full diff: v0.52.0…v0.53.0
✨ Highlights
- 🎯 Suspect lines — From per-test browser and server coverage, Piwi ranks the changed lines the failing tests executed, reads them against the file at the head commit, and shows them on the failure pages and in the cluster's diff.
- 🧪 Per-test server coverage — The ASP.NET Core instrumentation records each test's server code coverage, and the reporter sends it with the test.
- 🖱️ Live page state in the DOM view — The reporter captures focus, hover and selection at test end, and the DOM view shows the page's values, dialogs, focus, hover and the mouse.
- 🔁 Retries on the run timeline — The run timeline shows which failed attempts were retried and links a test's attempts.
- 🧱 One sample app for every backend — A sample app served by ASP.NET Core and Nitro replaces the Nitro example, and a Nitro module lists every route in the route manifest at build time.
