Are Instrumentation tests for Android Espresso available on CircleCi 2.0?

Question

Are Instrumentation tests for Android Espresso available on CircleCI 2.0? If yes, can anybody, please, help to configure config.yml file for me? I’ve made thousand attempts and no luck. I can run unit tests, but not Instrumentation.

Thanks

Answer 1

The answer for this question is: yes. Instrumentation tests are possible for CircleCi. This is the configuration I have:

version: 2
jobs:
  build:
    working_directory: ~/code
    docker:
        - image: circleci/android:api-25-alpha
    environment:
      JVM_OPTS: -Xmx3200m
    steps:
      - checkout
      - restore_cache:
          key: jars-{{ checksum "build.gradle" }}-{{ checksum  "app/build.gradle" }}
      - run:
          name: Chmod permissions #if permission for Gradlew Dependencies fail, use this. 
          command: sudo chmod +x ./gradlew
      - run:
          name: Download Dependencies
          command: ./gradlew androidDependencies
      - save_cache:
          paths:
            - ~/.gradle
          key: jars-{{ checksum "build.gradle" }}-{{ checksum  "app/build.gradle" }}
      - run:
          name: Setup emulator
          command: sdkmanager "system-images;android-25;google_apis;armeabi-v7a" && echo "no" | avdmanager create avd -n test -k "system-images;android-25;google_apis;armeabi-v7a"
      - run:
          name: Launch emulator
          command: export LD_LIBRARY_PATH=${ANDROID_HOME}/emulator/lib64:${ANDROID_HOME}/emulator/lib64/qt/lib && emulator64-arm -avd test -noaudio -no-boot-anim -no-window -accel on
          background: true
      - run:
          name: Wait emulator
          command: |
            # wait for it to have booted
            circle-android wait-for-boot
            # unlock the emulator screen
            sleep 30
            adb shell input keyevent 82
      - run:
          name: Run Tests
          command: ./gradlew connectedAndroidTest
      - store_artifacts:
          path: app/build/reports
          destination: reports
      - store_test_results:
          path: app/build/test-results

The only problem with this configuration that it doesn't lead to successfull build because of not enough memory error. If somebody has better configuration, please, share.

I am running Android UI tests on CircleCI MacOS executor. Here is my configuration:
