在swift中实现Screenplay模式的自动化测试

// 定义角色
class Actor {
    let name: String
    
    init(name: String) {
        self.name = name
    }
    
    // 执行任务
    func perform(task: Task) {
        task.actions.forEach { action in
            action.perform(on: self)
        }
    }
}

// 定义任务
class Task {
    let actions: [Action]
    
    init(actions: [Action]) {
        self.actions = actions
    }
}

// 定义动作
protocol Action {
    func perform(on actor: Actor)
}

// 示例动作：点击按钮
class TapButtonAction: Action {
    let button: Button
    
    init(button: Button) {
        self.button = button
    }
    
    func perform(on actor: Actor) {
        // 调用按钮点击的方法
        button.tap()
    }
}

// 示例动作：验证页面元素
class VerifyElementAction: Action {
    let element: Element
    let expectedValue: String
    
    init(element: Element, expectedValue: String) {
        self.element = element
        self.expectedValue = expectedValue
    }
    
    func perform(on actor: Actor) {
        // 调用页面元素验证的方法
        let actualValue = element.getValue()
        assert(actualValue == expectedValue, "验证失败")
    }
}

// 示例屏幕：登录页面
class LoginPage {
    let usernameField: TextField
    let passwordField: TextField
    let loginButton: Button
    
    init(usernameField: TextField, passwordField: TextField, loginButton: Button) {
        self.usernameField = usernameField
        self.passwordField = passwordField
        self.loginButton = loginButton
    }
    
    // 示例方法：输入用户名
    func enterUsername(username: String) {
        usernameField.setValue(username)
    }
    
    // 示例方法：输入密码
    func enterPassword(password: String) {
        passwordField.setValue(password)
    }
    
    // 示例方法：点击登录按钮
    func tapLoginButton() {
        loginButton.tap()
    }
}

// 示例元素：文本框
class TextField {
    var value: String
    
    init(value: String = "") {
        self.value = value
    }
    
    func setValue(_ value: String) {
        self.value = value
    }
    
    func getValue() -> String {
        return value
    }
}

// 示例元素：按钮
class Button {
    func tap() {
        // 点击按钮的操作
    }
}

// 示例的自动化测试
func testLogin() {
    // 创建角色
    let user = Actor(name: "User")
    
    // 创建屏幕和元素
    let usernameField = TextField()
    let passwordField = TextField()
    let loginButton = Button()
    let loginPage = LoginPage(usernameField: usernameField, passwordField: passwordField, loginButton: loginButton)
    
    // 定义任务和动作
    let loginTask = Task(actions: [
        TapButtonAction(button: loginPage.loginButton),
        VerifyElementAction(element: loginPage.usernameField, expectedValue: "JohnDoe"),
        VerifyElementAction(element: loginPage.passwordField, expectedValue: "123456")
    ])
    
    // 角色执行任务
    user.perform(task: loginTask)
}

// 执行测试
testLogin()
