Test running failed: Unable to find instrumentation info for: ComponentInfo{} — error trying to test in IntelliJ with Gradle

Question

Everytime I try to run my tests the console says this:

Running tests
Test running startedTest running failed: Unable to find instrumentation info for:
ComponentI         


        

Answer 1

For what it's worth, AS 2.3 got hung up when i created a custom test runner after using the regular test runner. I got the same error as posted in the question.

Deleting the Debug Configurations for ALL Android Instrumented Tests and rebuilding fixed it. I believe the problem lied in the fact you no longer can choose a custom runner in the Debug Configurations because it's most likely built in via gradle.
