In order: set up the test runner, write a first test, test interactions with userEvent, test async with findBy and waitFor, mock API calls, test edge cases, write integration tests, and learn best practices like testing behavior over implementation.
After you can test interactions. Async testing uses findBy queries and waitFor to test components that fetch data. Mock the API so your tests run fast and deterministically without a network.
After you can test individual components and async. Integration tests test multiple components working together, like a form updating a list or adding to a cart updating the cart.
