cometchat-native-testing

Purpose

Teaches Claude how to write and run tests against a CometChat React Native integration. Covers:

• Unit / component tests with Jest + React Native Testing Library (RNTL)
• How to mock @cometchat/chat-uikit-react-native and @cometchat/chat-sdk-react-native (both pull in native modules that fail in Node's jest-expo / jest-react-native environments)
• Testing custom bubbles, headers, composer actions, empty states
• Snapshot testing pitfalls specific to theme-driven components
• E2E with Detox (iOS + Android native drivers) vs Maestro (declarative YAML)
• Which tests catch real regressions vs which are flaky churn

Ground truth: @cometchat/chat-uikit-react-native@5.3.3's example jest config (examples/SampleAppWithPushNotifications/jest.config.js) and the standard RN testing toolkit docs (callstack.github.io/react-native-testing-library, wix.github.io/Detox, maestro.mobile.dev).
