A faulty unit test, where only one side-effect is tested, giving me credit for full function coverage
class DetailsViewMvcImplTest : Spek({
describe("The DetailsViewMvcImpl") {
var mockButton: MaterialButton? = null
var mockPhoto: AppCompatImageView? = null
var mockRootView: View? = null
var mockTitle: AppCompatTextView? = null
var uut: DetailsViewMvcImpl? = null

A simple MVC implementation, to demonstrate the fragility of unit tests
class DetailsViewMvcImpl() {
val button: MaterialButton
val photo: AppCompatImageView
val title: AppCompatTextView
init {
rootView = inflater.inflate(R.layout.details_fragment, parent, false)
button = findViewById(R.id.view_online_button)

The mocking set up of a unit test where the output of one function is not streamed into the input of the next function, but uses a generic matcher
whenever(userService.getUserName()).thenReturn("jsmith")
whenever(userService.getUserId()).thenReturn("123-456")
whenever(userService.getUrlToAvatarImage(any())).thenReturn("https://ddg.co/") // Generic matcher is prone to error

The mocking set up of a unit test where the output of one function streams into the parameter of another
whenever(userService.getUserName()).thenReturn("jsmith")
whenever(userService.getUserId()).thenReturn("123-456") // Output from here...
whenever(userService.getUrlToAvatarImage("123-456")).thenReturn("https://ddg.co/") // ... feeds into here

A correct example of how to unit test the PhotosController
class PhotosControllerTest : Spek({
describe("The PhotosController") {
var mockPhotosApiService: PhotosApiService? = null
var mockSchedulerForwarder: SchedulerForwarder? = null
var uut: PhotosController? = null
beforeEachTest {
// uut and supporting classes setup and mocked here
}
