GitHub Actions run Espresso tests - continuous-integration

Question

I am currently trying to get my Instrumentation tests to run using GitHub Actions. I have the unit tests running fine but I cannot seem to get the Espresso tests to run. I am currently trying:
- name: Run Instrumentation Tests (reactivecircus)
uses: reactivecircus/android-emulator-runner#v2.6.1
with:
api-level: 23
target: default
arch: x86
profile: Nexus 6
script: ./gradlew connectedCheck --stacktrace
And I get the result:
com.balsdon.ratesapp.behaviour.RateListActivityEntryBehaviourInstrumentedTest > recyclerViewClickOnItemChangesMain[test(AVD) - 6.0] FAILED
android.content.res.Resources$NotFoundException: Resource ID #0x7f0700d3
at android.content.res.Resources.getValue(Resources.java:1351)
Tests on test(AVD) - 6.0 failed: Instrumentation run failed due to 'android.content.res.Resources$NotFoundException'
> Task :app:connectedOfflinemockDebugAndroidTest FAILED
> Task :app:processOnlineecbDebugAndroidTestResources
> Task :app:processProductionDebugAndroidTestResources
FAILURE: Build failed with an exception.
* What went wrong:
Execution failed for task ':app:connectedOfflinemockDebugAndroidTest'.
> There were failing tests. See the report at: file:///Users/runner/runners/2.165.2/work/currency_list_app/currency_list_app/app/build/reports/androidTests/connected/flavors/OFFLINEMOCK/index.html
and when I use:
- uses: malinskiy/action-android/emulator-run-cmd#release/0.0.5
with:
cmd: ./gradlew integrationTest
api: 23
tag: default
abi: x86
I get
/Users/runner/android-sdk/platform-tools/adb -s emulator-5554 shell getprop sys.boot_completed
error: device 'emulator-5554' not found
The process '/Users/runner/android-sdk/platform-tools/adb' failed with exit code 1

Your emulator version that you run locally, it's most likely newer than API 23 android version. On github actions script you're running the emulator using API 23:
uses: reactivecircus/android-emulator-runner#v2
with:
api-level: 23
target: default
arch: x86
profile: Nexus 6
script: ./gradlew connectedCheck --stacktrace
and inside your project there is a app/src/main/res/drawable-v24 inside resources, thus it wont be available for emulators with < 24 API version. You either have to change that directory to be drawable-v23 or you move the resources to an other drawable that older versions can access.
Even if you change the drawable directory to drawable-v23, Espresso may have issues. You'll either have to resolve for that version or you'll have to use a newer API version for your GitHub action emulator, maybe the same as you have on your development environment.
