flutter_integration_test_demo

This demostrates a integration test in flutter.

Firebase Project

Project Id : flutter-integration-test-demo https://console.firebase.google.com/u/0/project/flutter-integration-test-demo/testlab/histories

Running using the flutter command

These tests can be launched with the flutter test command, where <DEVICE_ID>: is the optional device ID or pattern displayed in the output of the flutter devices command:

flutter test integration_test/app_test.dart -d <DEVICE_ID>

This runs the tests in foo_test.dart. To run all tests in this directory on the default device, run:

flutter test integration_test

Using Flutter Driver to Run Tests

flutter drive --driver=test_driver/integration_test.dart --target=integration_test/app_test.dart

Android

To run integration_test/foo_test.dart on a local Android device (emulated or physical):

./gradlew app:connectedAndroidTest -Ptarget=`pwd`/../integration_test/foo_test.dart

Create an APK using Gradle:

pushd android
# flutter build generates files in android/ for building the app
flutter build apk
./gradlew app:assembleAndroidTest
./gradlew app:assembleDebug -Ptarget=integration_test/<name>_test.dart
popd

Firebase Test Lab

Upload the build apks Firebase Test Lab, making sure to replace <PATH_TO_KEY_FILE>, <PROJECT_NAME>, <RESULTS_BUCKET>, and <RESULTS_DIRECTORY> with your values.

gcloud auth activate-service-account --key-file=<PATH_TO_KEY_FILE>
gcloud --quiet config set project <PROJECT_NAME>
gcloud firebase test android run --type instrumentation \
  --app build/app/outputs/apk/debug/app-debug.apk \
  --test build/app/outputs/apk/androidTest/debug/app-debug-androidTest.apk\
  --timeout 2m \
  --results-bucket=<RESULTS_BUCKET> \
  --results-dir=<RESULTS_DIRECTORY>

You can pass additional parameters on the command line, such as the devices you want to test on. See gcloud firebase test android run

iOS

To build integration_test/foo_test.dart from the command line, run:

flutter build ios --config-only integration_test/foo_test.dart

Execute this script at the root of your Flutter app:

output="../build/ios_integ"
product="build/ios_integ/Build/Products"
dev_target="14.3"

# Pass --simulator if building for the simulator.
flutter build ios integration_test/foo_test.dart --release

pushd ios
xcodebuild -workspace Runner.xcworkspace -scheme Runner -config Flutter/Release.xcconfig -derivedDataPath $output -sdk iphoneos build-for-testing
popd

pushd $product
zip -r "ios_tests.zip" "Release-iphoneos" "Runner_iphoneos$dev_target-arm64.xctestrun"
popd

You can verify locally that your tests are successful by running the following command:

xcodebuild test-without-building -xctestrun "build/ios_integ/Build/Products/Runner_iphoneos14.3-arm64.xctestrun" -destination id=<YOUR_DEVICE_ID>

Once everything is ok, you can upload the resulting zip to Firebase Test Lab (change the model with your values):

gcloud firebase test ios run --test "build/ios_integ/Build/Products/ios_tests.zip" --device model=iphone11pro,version=14.1,locale=fr_FR,orientation=portrait
