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.mikeestrada.test/android.test.InstrumentationTestRunner} 

It worked once, but I can't get the reports to recreate correctly. They are just blank, didn't test anything. I've tried a plethora of commands including

adb shell am instrument -w -r com.mikeestrada.test/android.test.InstrumentationTestRunner 

and

adb shell am instrument -w -r   com.mikeestrada.test/com.google.android.apps.common.testing.testrunner.GoogleInstrumentation TestRunner 

Here are my code snippets:

AndroidManifest.xml

If it means anything - the attributes of <instrumentation> in the manifest are colored red as if IntelliJ does not recognize them.

Any help is great, thanks!

You need to check which instrumentation packages have been installed on your device:

 adb shell pm list instrumentation 

Then verify whether com.mikeestrada.test is actually listed there.
