Error=Unable to find instrumentation info for: ComponentInfo{ }

Question

I am trying to stand up espresso tests but I keep getting this error:

INSTRUMENTATION_STATUS: Error=Unable to find instrumentation info for: ComponentInfo{com.mi         


        

Answer 1

Looking at your build.gradle file, the problem is actually that you don't have the following configuration in the defaultConfig section:

testInstrumentationRunner "com.google.android.apps.common.testing.testrunner.GoogleInstrumentationTestRunner"

Espresso requires GoogleInstrumentationTestRunner in order to work.

Also with a gradle build system you shouldn't need an AndroidManifest.xml for the test project because it is auto generated.
