With the com.android.test plugin, instrumented tests can reside in a separate Gradle module, isolated from the rest of the code.
Using this plugin in combination with AndroidX AppCompat, however, causes the IllegalStateException below upon launching an Activity.
The crash occurs in this scenario only! Building the same tests from the regular androidTest source set works just fine. Launching the app manually also works fine. All common explanations of the error below seem to not apply.
Caused by: java.lang.IllegalStateException: This app has been built with an incorrect configuration. Please configure your build for VectorDrawableCompat.

Reproduce the issue with this small demo project and the following commands.
Build app, androidTest, and the tests in the separate module.
./gradlew clean app:bundleDebug app:assembleDebugAndroidTest app-tests:assemble
Install the app.
bundletool build-apks --bundle=app/build/outputs/bundle/debug/app.aab --output=app/build/outputs/bundle/debug/app.apks
bundletool install-apks --apks=app/build/outputs/bundle/debug/app.apks
Install and run the tests from the app module. Works as expected ✌️
adb install -r app/build/outputs/apk/androidTest/debug/app-debug-androidTest.apk
adb shell am instrument -w biz.laenger.android.foo.app.test/biz.laenger.android.foo.app.FooTestApplicationRunner
Install and run the tests from the app-tests module. Causes the error 😕
adb install -r app-tests/build/outputs/apk/debug/app-tests-debug.apk
adb shell am instrument -w biz.laenger.android.foo.app.test/biz.laenger.android.foo.app.FooTestApplicationRunner
