<!-- Thanks for submitting a pull request! We appreciate you spending the time to work on these changes. Please follow the template so that the reviewers can easily understand what the code changes affect --> # Summary This PR adds E2E tests based on view screenshots done via `react-native-view-shot`. It only works with devices that have their [pixel ratio](https://reactnative.dev/docs/pixelratio) equal `3`. If you want to use device with different pixel ratio, you need to adjust it in `e2e/generateReferences.ts` viewport and regenerate reference images (see below). Steps to run tests: - Run Metro server for example app via `yarn start` in example app's directory - Run `example` app on platform of your choice (currently only Android & iOS are supported) via `yarn android` or `yarn ios` in example app's directory - Run `yarn e2e` in project's root directory to start Jest server - Select `E2E` tab in example app - Wait for tests to finish - You can see test results, as well as diffs (actual rendered svg vs reference image) in `e2e/diffs` directory Steps to add new test cases: - Put SVG of your choice to `e2e/cases` directory - Run `yarn generateE2eRefrences`, this will open headless chrome browser via `puppeteer` and snapshot all rendered SVGs to .png files and later use them as reference in tests - You should see new .png files in `e2e/references` - When you run E2E tests again, it will use new test case(s) you've added ## Test Plan https://github.com/software-mansion/react-native-svg/assets/41289688/24ee5447-ce9a-43b6-9dde-76229d25a30a https://github.com/software-mansion/react-native-svg/assets/41289688/71d1873f-8155-4494-80bd-e4c1fa72a065 ### What's required for testing (prerequisites)? See Summary ### What are the steps to reproduce (after prerequisites)? See Summary ## Compatibility | OS | Implemented | | ------- | :---------: | | iOS | ✅ | | Android | ✅ | | Web | ❌ | ## Checklist <!-- Check completed item, when applicable, via: [X] --> - [X] I have tested this on a device and a simulator - [x] I added documentation in `README.md` - [X] I updated the typed files (typescript) - [X] I added a test for the API in the `__tests__` folder --------- Co-authored-by: bohdanprog <bohdan.artiukhov@swmansion.com> Co-authored-by: Jakub Grzywacz <jakub.grzywacz@swmansion.com>
