Testing

Test scripts are added under scripts in the overall architecture, before the build commands.

React Native unit test

This is a basic example with jest, given that jest tests are defined in the package.json file.

npm test

Native Android

For non-UI tests or unit testing:

./gradlew test

UI tests (also known as instrumented tests):

./gradlew connectedAndroidTest

Native iOS

set -o pipefail
xcodebuild \
    -workspace MyAwesomeApp.xcworkspace \
    -scheme MyAwesomeApp \
    -sdk iphonesimulator \
    -destination 'platform=iOS Simulator,name=iPhone 6,OS=8.1' \
    test | xcpretty

If may want to export the test log, you can do this by splitting the standard output to a file

set -o pipefail
xcodebuild \
    -workspace MyAwesomeApp.xcworkspace \
    -scheme MyAwesomeApp \
    -sdk iphonesimulator \
    -destination 'platform=iOS Simulator,name=iPhone 6,OS=8.1' \
    test | xcpretty |& tee "/tmp/xcodetest.log"

Flutter test

flutter test

Tip: you can display Flutter test results visually in the build overview if you use expanded form of the script in codemagic.yaml. Just include the test_report field with a glob pattern matching the test result file location:

scripts:
  - echo 'previous step'
  - name: Unit tests
    script: |
      mkdir -p test-results
      flutter test --machine > test-results/flutter.json
    test_report: test-results/flutter.json

Flutter integration tests

The flutter_driver dependency allows you to run integration tests on a real device or emulator. Android application tests can be run on an Android emulator, iOS application tests can be run on an iOS simulator, and web application tests can be run on a web browser driver.

Running iOS/Android application tests on a mobile simulator/emulator

    flutter emulators --launch apple_ios_simulator             # for android use: flutter emulators --launch emulator
    flutter drive --target=test_driver/my_drive_target.dart

Running web application tests on a web browser driver

Chrome

  scripts:
    - echo 'previous step'
    - name: 'Flutter drive web test'
      script: |
        chromedriver --port=4444 &
        flutter config --enable-web
        flutter drive --target=test_driver/button_pressing.dart -d chrome --browser-name chrome --release

Safari

  scripts:
    - echo 'previous step'
    - name: 'Flutter drive web test'
      script: |
        sudo safaridriver --enable
        safaridriver --port 4444 &
        flutter config --enable-web
        flutter drive --target=test_driver/button_pressing.dart --browser-name safari --release
