How to run a JUnit Test in android studio?

Question

i think tests in the instruementTest should relevant to android, so need i add an addtional source folder such as src/test/java？ it looking that the testfile in src/test/java didn't compiled.

how can i run a junit test independently?

how can i run the junit test only in a command line, no the instrumentTest about android?

or put and junit test in the instruementTest folder and call

     ./gradlew connectedInstrumentTest

but,the unit test won't run at all.

I think this is not possible if you only have the Android plugin in your build.gradle. The only testing that is supported in the Android plugin is in the InstrumentTest folder. The normal test folder is only used by other plugins.

Next to that there is probably support needed in Android Studio itself. But not sure about that.
