If you're building Capacitor apps and need to test them properly, this covers the full pyramid: unit tests with Vitest, component tests with React Testing Library or Vue Test Utils, E2E tests with Playwright for web and Appium for native. The plugin mocking setup is especially useful since Capacitor's native APIs are a pain to test otherwise. It shows you how to mock everything from basic Capacitor.getPlatform() calls to third-party plugins like biometric auth. The guide assumes you know your way around testing in general and jumps straight into the Capacitor-specific challenges. It's thorough on the web side but the Appium section cuts off, so you'll want other resources for complete native E2E coverage.
