API Adding and modifying APIs Before performing the implementation, go over the steps to understand and plan the work ahead. It is important to follow the steps in order, as some of them are prerequisites for others. Define (or update) API in docs/api/class-xxx.md . For the new methods, params and options use the version from package.json (without -next). Watch will kick in and re-generate types for the API Implement the new API in packages/playwright/src/client/xxx.ts Define (or update) channel for the API in packages/protocol/src/protocol.yml as needed Watch will kick in and re-generate types for protocol channels Implement dispatcher handler in packages/playwright/src/server/dispatchers/xxxDispatcher.ts as needed Handler should just route the call into the corresponding method in packages/playwright-core/src/server/xxx.ts Place new tests in tests/page/xxx.spec.ts or create new test file if needed Build Assume watch is running and everything is up to date. Test If your tests are only using page, prefer to place them in tests/page/xxx.spec.ts and use page fixture. If you need to use browser context, place them in tests/library/xxx.spec.ts . Run npm test as npm run ctest Lint In the end lint via npm run flint .
