Chrome Ext Testing

Category: Engineering  ·  Sub-category: testing  ·  Last updated:
type:integration
This skill should be used when writing or setting up tests for a Chrome extension. Trigger when: "test chrome extension", "extension unit test", "extension e2e test", "Vitest extension", "Playwright extension", "@webext-core/fake-browser", "test content script", "test service worker", "test messaging", "test storage", "extension integration test", "test permission flow", "extension test framework", "mock chrome API", "browser mode testing".

From the source SKILL.md

Extension testing spans three tiers: unit tests for pure logic, integration tests for messaging/storage/UI, and E2E tests for multi-context journeys. Vitest with @webext-core/fake-browser handles the first two. Playwright handles E2E with real browser contexts.
