About this capability

Use when writing, running, or debugging tests in the Gutenberg repository — JavaScript unit tests (Jest), PHP tests (PHPUnit), or end-to-end tests (Playwright).

What this skill tells your AI

The instructions your AI receives, as published by wordpress/gutenberg in .agents/skills/testing/SKILL.md and read by ahel’s review.

Plan the tests with the author first

Before writing any test bodies, draft the test names — behavior from the user's perspective, one behavior per case (see Describing tests) — and confirm the list with the author. Every proposed case must trace to the behavior being added or changed; do not pad the list with adjacent or unrelated coverage. If working unattended, put the proposed list in your summary for review instead.

Never make a failing test pass by weakening it

No loosened assertions, no added waits or timeouts, no skipped cases without saying so. Diagnose the root cause, or report the failure honestly.

Never make a failing test pass by changing the production code unless the production code is the source of a bug

The e2e test passing is not the final task success criteria. The core goal is to verify that the production code works as expected.
