1. Prepare test environment

1.1. A Rocket.Chat server

Either

• Install Rocket.Chat meteor app by following this guide.

Or

• Use the local Docker environment available in this folder. You can start the environment using ./e2e/docker/controlRCDemoEnv.sh startandwait, or you can use the packaged start & run script (see step 3). Either way, you'll need Docker and Docker Compose.

1.2. Set up detox

• Install dependencies by following this guide (only Step 1).

2. Prepare test data

• If you're running your own Rocket.Chat server, ensure it's started (e.g. meteor npm start in the server project directory).
• Edit e2e/data.js:
  • Set the server to the address of the server under test
  • Set the adminUser and adminPassword to an admin user on that environment (or a user with at least create-user and create-c).
• Working example configs exist in ./e2e/data/. Setting FORCE_DEFAULT_DOCKER_DATA to 1 in the runTestsInDocker.sh script will use the example config automatically

3. Running tests

3.1. iOS

• Build app with detox: detox build -c ios.sim.release
• Open Simulator which is used in tests (check in package.json under detox section) from Xcode and make sure that software keyboard is being displayed. To toggle keyboard press cmd+K.
• Run tests: detox test -c ios.sim.release, or, if choosing Docker you can run the packaged environment & runner (./e2e/docker/runTestsInDocker.sh) which will start the Docker infrastructure, run the tests and tear it down again once done.

3.2. Android

• Build app with detox: detox build -c android.emu.debug
• Run: react-native start
• Run Android emulator with name ANDROID_API_28 via Android studio or cd /Users/USERNAME/Library/Android/sdk/emulator/ && ./emulator -avd ANDROID_API_28 Note: if you need to run tests on different Android emulator then simply change emulator name in ./package.json detox configurations
• Run tests: detox test -c android.emu.debug

3.3 Running a subset of tests

Tests have been grouped into subfolders. You can choose to run just one group of tests by running, for example:

detox test ./e2e/tests/onboarding -c ios.sim.release

To do the same with the Docker runner:

./e2e/docker/runTestsInDocker.sh onboarding

4. FAQ

4.1. Detox build fails

• Delete node_modules, ios/build, android/build: rm -rf node_modules && rm -rf ios/build && rm -rf android/build
• Install packages: yarn install
• Kill metro bundler server by closing terminal or with following command: lsof -ti:8081 | xargs kill
• Clear metro bundler cache: watchman watch-del-all && rm -rf $TMPDIR/react-native-packager-cache-* && rm -rf $TMPDIR/metro-bundler-cache-*
• Make sure you have all required environment.
• Now try building again with detox build (with specific configuration).

4.2. Detox iOS test run fails

• Check if your meteor app is running by opening localhost:3000 in browser.
• Make sure software keyboard is displayed in simulator when focusing some input. To enable keyboard press cmd+K.
• Make sure you have prepared all test data.
• Sometimes detox e2e tests fail for no reason so all you can do is simply re-run again.

• TOTP test
• Push notifications
