Josh Justice 43b56ecb24 Separate RTL examples in RNTester (#23354)
Summary:
Splits RTLExample into separate exported examples, so they can be filtered. This will help with Detox tests.

Previously the single forceRTL toggle affected multiple examples because they all share state—although the box model examples at the end had their own toggles. Now each example has its own RTL toggle so it is always available even when examples are filtered, and so the examples don't have to share state. There is still the separate forceRTL toggle that changes the setting in `I18nManager`, which affects the default setting when the page appears, as well as the direction of the "with directional meaning" pointer icon.

[General] [Changed] - Split RTLExample into separate exported examples

RNTester

The RNTester showcases React Native views and modules.

Running this app

Before running the app, make sure you ran:

git clone https://github.com/facebook/react-native.git
cd react-native
npm install

Running on iOS

Mac OS and Xcode are required.

  • Open RNTester/RNTester.xcodeproj in Xcode
  • Hit the Run button

See Running on device if you want to use a physical device.

Running on iOS with CocoaPods

Similar to above, you can build the app via Xcode with help of CocoaPods.

  • Install CocoaPods
  • Run cd RNTester; pod install
  • Open the generated RNTesterPods.xcworkspace (this is not checked in). Do not open RNTesterPods.xcodeproj directly.

Running on Android

You'll need to have all the prerequisites (SDK, NDK) for Building React Native installed.

Start an Android emulator (Genymotion is recommended).

cd react-native
./gradlew :RNTester:android:app:installDebug
./scripts/packager.sh

Note: Building for the first time can take a while.

Open the RNTester app in your emulator.

See Running on Device in case you want to use a physical device.

Running with Buck

Follow the same setup as running with gradle.

Install Buck from here.

Run the following commands from the react-native folder:

./gradlew :ReactAndroid:packageReactNdkLibsForBuck
buck fetch rntester
buck install -r rntester
./scripts/packager.sh

Note: The native libs are still built using gradle. Full build with buck is coming soon(tm).

Running Detox Tests on iOS

Install Detox from here.

To run the e2e tests locally, run the following commands from the react-native folder:

yarn build-ios-e2e
yarn test-ios-e2e

These are the equivalent of running:

detox build -c ios.sim.release
detox test -c ios.sim.release --cleanup

These build the app in Release mode, so the production code is bundled and included in the built app.

When developing E2E tests, you may want to run in development mode, so that changes to the production code show up immediately. To do this, run:

detox build -c ios.sim.debug
detox test -c ios.sim.debug

You will also need to have Metro Bundler running in another terminal. Note that if you've previously run the E2E tests in release mode, you may need to delete the RNTester/build folder before rerunning detox build.

Built from source

Building the app on both iOS and Android means building the React Native framework from source. This way you're running the latest native and JS code the way you see it in your clone of the github repo.

This is different from apps created using react-native init which have a dependency on a specific version of React Native JS and native code, declared in a package.json file (and build.gradle for Android apps).
