Byte buddy exceptions cause Android instrumented tests to fail.
See original GitHub issueBackground:
I attempted to upgrade a fairly large project from mockitio 1x to 2x. I discovered that mockito 2 tests work only when run using the gradle wrapper, not when launched more directly with adb. The gradle wrapper is sufficient for smaller projects but we are using adb for its ability to shard tests across multiple agents. Mockito 1.x does not have this limitation.
Environment: OS: OSX 10.12.2 IDE: Android Studio 2.3 Beta 2 Android Device: Emulator API 24
Steps:
- Create new Android Studio project (Application name: Scheme, Company domain: countolaf.example.com, Min SDK: 19, Type: Empty Activity) NOTE) A single empty unit test has been created on our behalf.
- Add mockito dependency to the application’s build.gradle (
androidTestCompile org.mockito:mockito-android:2.6.3") - Launch emulator (API 24 in this case)
- Build and install the application
/gradlew clean installDebug installDebugAndroidTest - Launch instumented tests using gradle
./gradlew connectedAndroidTest - OBSERVE The following exceptions printed to logcat

I’m proposing this issue be opened again. It hasn’t been fixed on Android Testing Support Library 1.0.0. I’ve actually tested with 1.0.2 and it is still there. Also, the above AOSP patch hasn’t been merged either.
We’re seeing this now from moving from testing 1.0.2 to 1.1.1 (via androidx)
