Android Expresso android.util.AndroidException: INSTRUMENTATION_FAILED with product flavors

I am using Product Flavors with Android Expresso.

When running the tests I get the following error:

android.util.AndroidException: INSTRUMENTATION_FAILED: http://ift.tt/2yLvu5N
 nstrumentation stderr:
 nstrumentation stderr:

 INSTRUMENTATION_STATUS: Error=Unable to find instrumentation info for: ComponentInfo{http://ift.tt/2yLvu5N}
 INSTRUMENTATION_STATUS_CODE: -1
 nstrumentation stdout:
 nstrumentationProcess terminated due to receipt of signal null

Then when running adb shell pm list instrumentation it doesn't show the dev target:

instrumentation:com.android.emulator.smoketests/android.support.test.runner.AndroidJUnitRunner (target=com.android.emulator.smoketests)
instrumentation:com.android.smoketest.tests/com.android.smoketest.SmokeTestRunner (target=com.android.smoketest)
instrumentation:http://ift.tt/1kgLcJ4 (target=com.example.android.apis)
instrumentation:http://ift.tt/2yLwvLa (target=com.app.android)
instrumentation:org.chromium.webview_shell/.WebViewLayoutTestRunner (target=org.chromium.webview_shell)

I have tried setting the testApplicationId like it says here to com.app.android.dev.test but the target in the instrumentation stays set to target=com.app.android.
