Are Instrumentation tests for Android Espresso available on CircleCi 2.0? - circleci

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.
