About e2e-tests-studio

e2e-tests-studio
REQUIRED when modifying any file in packages/playground-ui or
E2E-tests-studio is an agent skill that sets the rules for end-to-end tests when someone changes the Mastra playground interface. It applies whenever a file in the playground UI or playground packages is created, modified or refactored, including React component work and UI changes. Its central principle is to test product behavior rather than interface states. The skill lists examples of what not to test, such as whether a dropdown opens, a modal appears, a spinner shows, form fields are visible or a sidebar collapses, because those checks pass without proving that the feature works. It asks the tests to confirm that the product feature itself works, not only that its controls appear. The skill is part of the Mastra repository and is published on skills.sh by the Mastra team. It is aimed at engineers who contribute to Mastra Studio and must keep its behavior tested after each change.
