Addfox Testing

Use this skill to implement automated testing for Addfox extensions.

When to use

• Creating unit tests for extension logic and utilities
• Mocking chrome.* or browser.* APIs
• Adding Playwright E2E tests for popup/content/background flows
• Running extension tests in CI

Test strategy

Minimum setup

• Add Rstest config and setup file for API mocks.
• Build extension before E2E (addfox build).
• Launch browser context with extension from .addfox/extension.

Best practices

• Keep unit tests fast and isolated.
• Use E2E for critical cross-context flows.
• Run test matrix on Chromium + Firefox when applicable.
