CyxouD / Model-View-Presenter Communication.kt

Last active April 8, 2019 12:18

Examples of tests for: 1) testing MVP architecture (Model-View-Presenter Communication.kt) - tests communication between view and presenter and mocking repository behavior; 2) Repository (Repository.kt) - tests how data from local data source and remote data source is received and processed; 3) UI (UI (Integration).kt) - tests UI behavior

	//imports are missing
	class CardsListPresenterTest {
	private lateinit var presenter: CardsListPresenter
	private val view = mock<CardsListContact.View>()
	private val repository = mock<Repository>()
	private val scheduleProvider = ImmediateSchedulerProvider()

	// ... some other tests

Model-View-Presenter+Repository architecture example

	//contract which declare action of Presenter and MVP View
	interface AddEditCardContract {
	interface Presenter : BasePresenter {
	fun getCreditCardLogo(creditCardNumber: String)
	fun validateCreditCardNumber(creditCardNumber: String)
	fun validateCreditCardHolder(creditCardHolder: String)
	fun validateCreditCardExpiryDate(creditExpiryDate: String)
	fun validateCreditCardCVV(creditCVV: String)
	fun validateCreditCardTypeAndPriority(creditCardType: String, creditCardPriority: String)
	fun saveCreditCard(number: String,

Contract (interface) which declare action of Presenter and MVP View. In this case AddEditCardFragment will implement AddEditCardContract.View interface and AddEditCardPresenter will implement AddEditCardContract.Presenter interface

	interface AddEditCardContract {
	interface Presenter : BasePresenter {
	fun getCreditCardLogo(creditCardNumber: String)
	fun validateCreditCardNumber(creditCardNumber: String)
	fun validateCreditCardHolder(creditCardHolder: String)
	fun validateCreditCardExpiryDate(creditExpiryDate: String)
	fun validateCreditCardCVV(creditCVV: String)
	fun validateCreditCardTypeAndPriority(creditCardType: String, creditCardPriority: String)
	fun saveCreditCard(number: String,
	holderName: String,

CyxouD / AddEditCardFragment.kt

Created July 19, 2018 14:59

Fragment which is MVP View which can show credit card logo, show that there is no credit card logo, show credit card number was validated successfully etc (everything defined in AddEditCardContract.kt)

	//MVP View
	class AddEditCardFragment : BaseFragment<AddEditCardContract.Presenter>(), AddEditCardContract.View {

	// ...Android lifecycle methods

	override fun setPresenter(presenter: AddEditCardContract.Presenter) {
	mPresenter = presenter
	}

	override fun showCreditCardLogo(creditCardEnum: CreditCardEnum) {

Organize between with View (view: AddEditCardContract.View) and Model (repository: DataSource). Performs logic which is not View-dependant and process data from Model before passing it to View

	class AddEditCardPresenter(override val repository: DataSource,
	val view: AddEditCardContract.View,
	override val schedulerProvider: BaseSchedulerProvider,
	override val mCompositeDisposable: CompositeDisposable = CompositeDisposable()) : AddEditCardContract.Presenter {
	init {
	view.setPresenter(this)
	}

	override fun subscribe() {
	}

	companion object {
	private var INSTANCE: LocalDataSource? = null


	fun getInstance(): LocalDataSource {
	if (INSTANCE == null) {

CyxouD / RemoteDataSource.kt

This file is responsible for handling network request using Retrofit and pass result with RxJava Observables

	open class RemoteDataSource private constructor() : DataSource {

	private val service by lazy {
	RetrofitService.create()
	}


	companion object {
	private var INSTANCE: RemoteDataSource? = null

CyxouD / Repository.kt

Created July 19, 2018 15:07

This file is responsible for organizing communication between local and remote data sources (storages) and passing result with RxJava Observables

	open class Repository private constructor(
	remoteDataSource: DataSource,
	localDataSource: DataSource)
	: DataSource {

	private val mRemoteDataSource = remoteDataSource
	private val mLocalDataSource = localDataSource

	companion object {

CyxouD / RetrofitService.kt

Created July 19, 2018 15:09

Interface, which declare PUT, GET, POST etc methods, which Retrofit (Http network client) will use to create network requests

	interface RetrofitService {
	companion object {
	fun create(): DevGetVoilaService {
	val clientBuilder = OkHttpClient.Builder().apply {
	val loggingInterceptor = HttpLoggingInterceptor()
	loggingInterceptor.level = HttpLoggingInterceptor.Level.BODY
	addInterceptor(loggingInterceptor)
	addInterceptor(AuthenticationInterceptor())
	addInterceptor(AuditInterceptor())
	}

Make all libraries to use same support libs version (26.1.0 in this case) - place it in your root build.gradle (I placed in build script)

	subprojects {
	project.configurations.all {
	resolutionStrategy.eachDependency { details ->
	if (details.requested.group == 'com.android.support'
	&& !details.requested.name.contains('multidex') ) {
	details.useVersion "26.1.0"
	}
	}
	}
	}
