Integration tests

The integration tests in this directory can be run with yarn test-ui.

• To run all tests from a specific file, use yarn test-ui testFileName. For example, yarn test-ui wcag to run the tests in wcag.ts.
• To run all tests matching a pattern, use yarn test-ui -g "pattern here", where -g is short for "grep".
• Tests use a test-profile directory that should be re-created before every test.
• Only one Electron application should be instantiated per test file.
• Files in the models/ directory follow the page object model.

FAQ

How do I fix timeout-related test failures?

If Playwright tests are timing out, consider modifying playwright.config.ts in the app-desktop folder. For example, increase the timeout option to 120_000 (2 minutes).

Alternatively, try temporarily disabling fullyParallel (which disables running tests in parallel).
