There is no convention for this yet, but how do I structure the test directory for Android Studio, now that what\'s stated on the Android testing fundamentals page differs?
i have another way to solve this problem , if your reason just is the problem of run configuration.
check your run configuration , if the configuration of your project is Android Tests but not Android Application and then you will face
"Running tests
Test running startedTest running failed: Unable to find instrumentation info for:ComponentInfo{/android.test.InstrumentationTestRunner}
Empty test suite."
so delete the Android Tests configuration and add a Android Application run configuration for your peoject ,you can run it .
