iOS Boot Camp

1. Create VIPER template use ruby script

   ruby scripts/generator.rb -m "SignUp" -t ./templates -w TooDoApp/TooDoApp/Modules -u TooDoApp/TooDoAppTests/Modules -a "<Your name>"

2. Import generated file to project

3. Add Modules.swift path to Module

   case .SignUp:
       return "/Modules/SignUp"

4. Add module to AppRouter.swift

   Module.SignUp.routePath : {(appRouter: IAppRouter) in SignUpModule(appRouter: appRouter)}

5. Un-commented this code on SignUpModule.swift

   let wireframe = appRouter.resolver.resolve(ISignUpWireFrame.self, argument:appRouter)!
       wireframe.present(SignUpViewModel())

6. Add some protocol needed, example: we want show SignUp screen and show List of todo after SignUp

   func presentView(viewModel:SignUpViewModel)
   func showListScreen()

7. Add method in SignUp presenter and Interface to do SignUp

   func doSignUp(email: String?, password: String?, confirmPassword: String?)
   func didSignUp(user: User)
   func failedToSignUp(error: NSError?)

8. Un-wrapped all optional value to check not get nil value

9. Make sure all view action registered to viewInterface

   func showLoading()
   func hideLoading()
   func showErrorMessage(message: String)

10. Add service on Interactor

    let service:ITodoService
    
    init(service:ITodoService){
    
       self.service = service
       
    }

Step to create Unit Test

1. Make sure All file Target Membership can accessed by <#AppName>Test and <#AppName>UITest

2. Create Mock, Make sure pod already have MockFive installed

   import Foundation
   import MockFive
   
   class SignUpViewMock: ISignUpView, Mock {
       let mockFiveLock: String = lock()
   
       func showLoading() {
           stub(identifier: "show Loading")
       }
   
       func hideLoading() {
           stub(identifier: "hide Loading")
       }
   
       func showErrorMessage(message: String) {
           stub(identifier: "show Error Message", arguments: message)
       }
   }

   import Foundation
   import MockFive
   
   class SignUpWireFrameMock: ISignUpWireFrame, Mock {
       let mockFiveLock: String = lock()
   
       func presentView(viewModel: SignUpViewModel) {
           stub(identifier: "present View")
       }
   
       func showListScreen() {
           stub(identifier: "show List Screen")
       }
   }

   import Foundation
   import MockFive
   
   class SignUpIteractorMock: ISignUpInteractor, Mock {
       let mockFiveLock: String = lock()
   
       var _presenter: ISignUpPresenter?
   
       var presenter : ISignUpPresenter?{
           set { _presenter = newValue }
           get { return _presenter }
       }
   
       func signUp(email: String, password: String, confirmPassword: String) {
           stub(identifier: "sign Up", arguments: [email, password, confirmPassword])
           _presenter?.doSignUp(email, password: password, confirmPassword: confirmPassword)
       }
   }

   import Foundation
   import Quick
   import Nimble
   
   @testable import TooDoApp
   
   class SignUpPresenterTest: QuickSpec {
       override func spec() {
           var viewModel:SignUpViewModel!
           let viewMock = SignUpViewMock()
           let wireFrameMock = SignUpWireFrameMock()
           let interceptorMock = SignUpIteractorMock()
           var presenter: SignUpPresenter!
       
           beforeEach{
               viewModel = SignUpViewModel()
               viewMock.resetMock()
               wireFrameMock.resetMock()
               interceptorMock.resetMock()
               presenter = SignUpPresenter(view: viewMock, viewModel: viewModel, interactor: interceptorMock, wireframe: wireFrameMock)
               interceptorMock.presenter = presenter
           }
       }
   }

3. Make all presenter test case

   describe("Sign Up Test") {
           it("Invalid Sign Up : Invalid Email Address", closure: {
               presenter.doSignUp("", password: "", confirmPassword: "")
               expect(viewMock.invocations.count) == 1
               expect(viewMock.invocations).to(contain("showErrorMessage(Please enter a valid email)"))
           })
           
           it("Invalid Sign Up : Invalid Password", closure: { 
               presenter.doSignUp("[email protected]", password: "", confirmPassword: "")
               expect(viewMock.invocations.count) == 1
               expect(viewMock.invocations).to(contain("showErrorMessage(Please enter a valid password)"))
           })
           
           it("Invalid Sign Up : Confirm password did not match", closure: {
               presenter.doSignUp("[email protected]", password: "password", confirmPassword: "")
               expect(viewMock.invocations.count) == 1
               expect(viewMock.invocations).to(contain("showErrorMessage(Your password and confirm password did not match)"))
           })
   }
