swift – 测试出现和消失的动画标签的文本

private func registerNewUser(email: String,password: String,confirmationPassword: String) {
    if password == confirmationPassword {
        firebaseData.createUser(email: email,password: password,completion: { (error,_ ) in
            if let error = error {
                self.showToast(in: self.view,with: error.localizedDescription)
            } else {
                self.showToast(in: self.view,with: "Registered succesfully")
                self.signInUser(email: email,password: password)
            }
        })
    } else {
        //raise password mismatch error
        print("password mismatch error")
    }
}

func showToast(in toastSuperView: UIView,with text: String) {
    let toastLabel = ToastLabel()
    toastLabel.text = text
    toastSuperView.addSubview(toastLabel)
    layoutToastLabel(toastLabel)
    animateToastLabel(toastLabel)
}

private func layoutToastLabel(_ toastLabel: ToastLabel) {
    toastLabel.centerYToSuperview()
    toastLabel.pinToSuperview(edges: [.left,.right])
}

private func animateToastLabel(_ toastLabel: ToastLabel) {
    UIView.animate(withDuration: 2.5,delay: 0,options: .curveEaSEOut,animations: {
        toastLabel.alpha = 0.0
    },completion: { _ in
        toastLabel.removeFromSuperview()
    })
}

我只想测试在用户输入已经拍摄的电子邮件后出现从firebase收到的错误文本.

func testRegisteringWithUsedEmailDisplaysFirebaseError() {
    let email = registeredEmail
    let password = "password"

    welcomeScreenHelper.register(email: email,confirmationPassword: password,completion: {

        let firebaseErrorMessage = "The email address is already in use by another account."
        XCTAssert(self.app.staticTexts[firebaseErrorMessage].exists)
    })
}

func register(email: String,confirmationPassword: String,completion: (() -> Void)? = nil) {
    let emailTextField = app.textFields[AccesID.emailTextField]
    let passwordTextField = app.secureTextFields[AccesID.passwordTextField]
    let confirmPasswordTextField = app.secureTextFields[AccesID.confirmPasswordTextField]
    let registerButton = app.buttons[AccesID.registerButton]

    emailTextField.tap()
    emailTextField.typeText(email)
    passwordTextField.tap()
    passwordTextField.typeText(password)
    registerButton.tap()
    confirmPasswordTextField.tap()
    confirmPasswordTextField.typeText(confirmationPassword)
    registerButton.tap()

    completion?()
}

当我使用期望和XCTWaiter等其他工具时,尽管文本和标签肯定出现,但测试仍然没有通过.我从来没有做过这样的测试所以我不确定我可能会出错的地方,我是否必须做一些不同的测试动画视图或其他东西.

UPDATE1：

所以我可以看到更多的播放后,当我点击registerButton吐司出现,但测试不会继续,直到它再次消失.我觉得这很奇怪,因为它没有严格依附于registerButton是它自己的视图.

UPDATE2：

我更新了我的测试如下：

func testRegisteringWithUsedEmailDisplaysFirebaseError() {

    welcomeScreenHelper.register(email: registeredEmail,completion: {

        let firebaseErrorMessage = "The email address is already in use by another account."

        let text = self.app.staticTexts[firebaseErrorMessage]
        let exists = NSPredicate(format: "exists == true")

        self.expectation(for: exists,evaluatedWith: text,handler: nil)
        self.waitForExpectations(timeout: 10,handler: nil)
        XCTAssert(self.app.staticTexts[firebaseErrorMessage].exists)
    })
}

增加：

override func setUp() {
    app.launch()
    UIView.setAnimationsEnabled(false)
    super.setUp()
}

override func tearDown() {
    if let email = createdUserEmail {
        firebaseHelper.removeUser(with: email)
    }
    UIView.setAnimationsEnabled(true)
    super.tearDown()
}

但到目前为止还没有运气.我仍然可以看到在func寄存器中,一旦注册按钮被点击,吐司显示并且在toastLabel完成动画之前不会调用下一行.
