# 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
