Use this skill to update existing web renderer tests when needed for implementation changes. Add new tests only when the user explicitly requests them. The web renderer is in packages/web renderer and the test suite is in packages/web renderer/src/test . It uses visual snapshot testing using vitest. A test file can for example be executed using: Example Each test is powered by a fixture in packages/web renderer/src/test/fixtures . A fixture looks like this for example: The corresponding test looks like this: Adding a new test 1. Add a new fixture in packages/web renderer/src/test/fixtures . 2. Important : Add the fixture to packages/web renderer/src/test/Root.tsx to add a way to preview it. 3. Add a new test in packages/web renderer/src/test . 4. Run bunx vitest src/test/video.test.tsx to execute the test. 5. Important : Update packages/docs/docs/client side rendering/limitations.mdx to reflect the newly supported property.
