Can Android tests be developed in Java for a Kotlin application? How about Kotlin tests in a Java application?

I am very new to test development inside an Android environment and I am trying to figure out if I can use frameworks such as Mockito for test development in Kotlin and this question came to mind.

Yes, though you will need to deal with Java-Kotlin interop concerns.

How about Kotlin tests in a Java application?

That depends on what you mean by "a Java application":

  • If you mean an app that is not configured for Kotlin support via Gradle, then you cannot write Kotlin anywhere in that app, whether in tests or anywhere else

  • If you mean an app that is configured for Kotlin support but just happens to only have Java code, then yes, you can write tests in Kotlin (with similar interop concerns)

Yes, though frequently there is already a Kotlin wrapper for those things. In the case of Mockito, mockito-kotlin works nicely.
