Differences between testCompile and androidTestCompile for junit imports

Question

What is the difference between these two import statements? (in build.gradle ):

testCompile 'junit:junit:4.12'

androidTestCompile 'junit:junit:4.12'

Answer 1

There's a great answer here explaining the difference:

Simply testCompile is the configuration for unit tests (located in src/test ) and androidTestCompile is used for the test API (located in src/androidTest ).

...

The main distinction between the two is the test sourceset runs in a regular Java JVM, whereas the androidTest sourceset tests run on an Android device (or an emulator).
