You can automate end-to-end browser tests by running Playwright to validate API integrations, state transitions, and full user journeys. This approach applies layered test strategies across component, integration, and end-to-end scenarios to reduce flaky UI tests.

Yes, you can use MSW mocks with Playwright for browser testing. The Skill supports switching between mocked API responses and a real backend, allowing you to balance testing speed and realism across your end-to-end user journeys.

Yes, you need Vitest to execute deterministic browser tests with this Skill. It requires Playwright, Vitest, and a configured dev environment to run layered test strategies effectively across unit-level component tests and full-flow scenarios.

The best way to test state transitions and error recovery is using layered end-to-end testing with Playwright. It validates reliable UI journeys by automating browser-driven flows and error handling across layers, reducing manual debugging efforts.

Layered testing works by validating browser-driven flows across component, integration, and end-to-end levels using Playwright. It applies test strategies across unit-level component tests and API integration checks to ensure deterministic browser test execution.

UI tests are flaky when lacking layered strategies across API integrations and state transitions. Using Playwright with MSW mocks or a real backend helps validate error handling and user journeys deterministically, reducing manual debugging.
