As per the migration plan shared last year, this migrates all browser-based tests in WordPress core to use Playwright.
This includes end-to-end, performance, and visual regression tests.

Three new metrics are being collected and reported as part of this change:
- Time To First Byte (TTFB) - the time between the request for a resource and when the first byte of a response begins to arrive
- Largest Contentful Paint (LCP) — the render time of the largest image or text block visible within the viewport
- The difference between the two (LCP minus TTFB)

This adds a new GitHub Action workflow that measures a set of performance metrics on every commit, so we can track changes in the performance of WordPress over time and more easily identify changes that are responsible for significant performance improvements or regressions during development cycles.
The workflow measures the homepage of a classic theme (Twenty Twenty-One) and a block theme (Twenty Twenty-Three) set up with demo content from the Theme Test Data project. Using the e2e testing framework, it makes 20 requests and records the median value of the following Server Timing metrics, generated by an mu-plugin installed as part of this workflow:
- Total server response time
- Server time before templates are loaded
- Server time during template rendering
In addition to measuring the performance metrics of the current commit, it also records performance metrics of a consistent version of WordPress (6.1.1) to be used as a baseline measurement in order to remove variance caused by the GitHub workers themselves from our reporting.
The measurements are collected and displayed at https://www.codevitals.run/project/wordpress.
