activitypub-testing

PHPUnit tests for ActivityPub cover unit testing of PHP components like transformers and handlers. Structure tests using PHPUnit patterns, utilize test data factories to create realistic users and posts, mock HTTP requests for federation scenarios, and leverage test utilities to ensure reproducible, well-structured tests across environments.

Yes, Playwright E2E tests verify ActivityPub web features like settings page loading and WebFinger discovery. Write end-to-end tests to confirm user experience and federation capabilities function correctly, ensuring settings render properly and federation endpoints respond as expected.

Test data factories create realistic users, posts, and comments for ActivityPub scenarios. These factories generate consistent test data across test runs, enable mocking of federation interactions, and support both PHPUnit and Playwright tests to ensure reproducible testing environments.

ActivityPub testing includes debugging workflows for both PHPUnit and Playwright, with coverage reporting to identify gaps. Use test grouping annotations, examine mocked HTTP requests, and review test utilities to isolate failures and verify federation logic behaves correctly.

ActivityPub testing uses both tools for complete coverage: PHPUnit handles backend logic like transformers and handlers, while Playwright tests end-to-end user workflows and federation. Together they ensure backend correctness and real-world federation scenarios work as designed.
