Setting up tests

[mbobiosio]

I have followed the recommendations on this discussion but it doesn't solve my issue.
Android Studio runs the build process successfully, shows "Test Passed" but no test in particular indicated. The app is not started on the device (emulator and mobile phone) during this process.

The expected output

Android Studio version: Android Studio Arctic Fox | 2020.3.1
Java version: Java 8
OS: Ubuntu 22.04.1 LTS

If you run the test using the CLI in a local terminal, does it work? I think the command in your case would be:

./gradlew -Pandroid.testInstrumentationRunnerArguments.class=org.oppia.android.app.administratorcontrols.AdministratorControlsActivityTest :app:connectedAndroidTest

Also, have you checked the logcat logs on your device/emulator after starting the test? It may be the case that the app is misbehaving.

While google/dagger#3223 was caused by something that couldn't break for us, it's noteworthy because the issue illustrated there might also affect us (specifically the fact that we use a custom runner which might not be playing nicely with the latest Android Studio or AGP version).

Edit: Sometimes this issue can come up if the app fails to start (or, in your case, install). You can force a clean state by manually uninstalling the app via the system's app package manager, or via ADB on the CLI using:

adb uninstall org.oppia.android

[mbobiosio]

CLI throws com.android.ddmlib.InstallException

com.android.builder.testing.api.DeviceException: com.android.ddmlib.InstallException: INSTALL_FAILED_UPDATE_INCOMPATIBLE: Package org.oppia.android.test signatures do not match previously installed version; ignoring!

I have used 'clear app data - uninstall' and rerun test but still the same outcome. This happens both for emulator and mobile.

Try fully uninstalling the app either through the device's app package manager or via:

adb uninstall org.oppia.android

I am almost certain this is the issue that you're running into.

This doesn't solve my issue unfortunately

@mbobiosio could you include a bit more details, e.g.: are you still experience the exact same stack trace? If not, what new error are you seeing (as it may be an unrelated problem to the original one asked in this discussion).

@mbobiosio I think you have to downgrade your Android Studio to Bumblebee to run the tests on that or check this disscusion here you able to find the solution.
