Quick workaround to mock a context.getResources().getStringArray(...), in Kotlin

BaseTest.kt

    @Mock
    lateinit var mockContext: Context
    @Mock
    lateinit var mockResources: Resources

    @Before
    fun setUp() {
        MockitoAnnotations.initMocks(this)
    }

    protected fun givenThatAllStringsAreMocked() {
        whenever(mockContext.getString(anyInt())).thenReturn("-")
        whenever(mockContext.resources).thenReturn(mockResources)
        whenever(mockResources.getStringArray(anyInt())).thenReturn(arrayOf(
                "-", "-", "-", "-", "-", "-", "-", "-"
        ))
    }

Cleaner way to avoid mocking Context, or Resources

interface GetStringArray {
    fun getStringArray(id: Int) : List<String>
}

class GetStringArrayImpl(val appContext: Context) : GetStringArray {
    override fun getStringArray(id: Int) : List<String> {
        return appContext.resources.getStringArray(id)
    }
}
