Getting started with Playwright component testing

The development of web applications has evolved to use frameworks like React, Vue, and Svelte, which focus on building small, reusable components rather than individual HTML files for each page. Testing practices have similarly advanced from just end-to-end (E2E) tests to include unit tests for individual components. Playwright, an open-source testing tool initially designed for E2E testing, now offers an experimental component testing feature for React, Vue, and Svelte, allowing developers to write unit tests directly for their frontend components. This tutorial guides users through setting up and executing component tests with Playwright for these frameworks, using a monorepo project that displays data from the Rick and Morty API. While the component testing feature is still experimental and lacks support for Angular, it represents a significant step towards more granular testing capabilities within Playwright. The tutorial also advises on prerequisites and provides steps to set up, write, and run tests, emphasizing the importance of this feature in modern software development.
