Is there a way to build an in memory database with room and spock for testing purpose? I tried already different approaches but nothing seems to be working.



 libraryDatabase = Room.inMemoryDatabaseBuilder(ApplicationProvider.applicationContext, LibraryDatabase.class).allowMainThreadQueries().build()


I think the main problem here is the Context, but i tried to use:



  • Mock(Context)

  • ApplicationProvider.getApplicationContext()

But get Exceptions like:




java.lang.IllegalStateException: No instrumentation registered! Must run under a registering instrumentation.
at androidx.test.platform.app.InstrumentationRegistry.getInstrumentation(InstrumentationRegistry.java:45)
at androidx.test.core.app.ApplicationProvider.getApplicationContext(ApplicationProvider.java:41)




Has anybody some idea or a tip? How i can test my sqlite database with room in memory database and spock?
