Saw a similar error when running a test on an emulator unrelated to circleci. It was due to lack of storage space. Freeing some memory and retrying fixed it.

  • Faced this issue recently while running tests on an emulator, I saved myself some time by connecting my phone to my computer instead. I was able to run the test on a physical device. – Eaweb Dec 12 '22 at 09:13

Got the same problem after installing android studio on a new computer, and running instrumented tests on a connected device which I used previously to run my tests:

> Task :sdk-android:connectedDebugAndroidTest FAILED
Unknown platform error occurred when running the UTP test suite. Please check logs for details.

Then try again running those tests by command line with --debug option give more details about the problem:

./gradlew -Pandroid.testInstrumentationRunnerArguments.class=<MY_PACKAGE>.UnitTestSuite --debug

logs:

Caused by: com.google.testing.platform.core.error.UtpException: ErrorName: INSTALL_FAILED_UPDATE_INCOMPATIBLE

2023-02-14T16:32:41.454+0100 [ERROR] [org.gradle.api.Task] Unknown platform error occurred when running the UTP test suite. Please check logs for details.
2023-02-14T16:32:41.455+0100 [QUIET] [org.gradle.api.Task]

So in my case, it was just a problem of adb being unable to update test app. Just remove it from the device, then it worked for me!

Have you tried to update your IDE? It looks like a bug to me

For us, the CI server had plenty of space remaining but we still encountered the Unknown platform error occurred when running the UTP test suite. error. I found that using the -wipe-data option when launching the emulator on our server resolved the issue. As per the documentation, using the -wipe-data option removed the app state that had been preserved across restarts and freed up the memory needed to run the tests.

The virtual device preserves the app and its state data across restarts, in a user-data disk partition (userdata-qemu.img). To clear this data, start the emulator with the -wipe-data option or wipe the data in the AVD Manager, for example. For more information about the user-data partition and other storage, see the following section.

The full example command is: emulator @AVD_NAME -wipe-data.

The problem could be two things. The first is to verify if the Android dependencies are correctly implemented (there is a difference between androidTestImplementation and testImplementation) and also the folders. In Android, there are two folders, androidTest and test. I think you should choose test.
