Mac Dev Part 5 - NSAlertView &am

时间挤的话,总是会有的

比如说需求做完的时候,等同事接入的时候

1.NSAlert的两种弹出方式

首先创建NSAlert,并添加选项

        let alert = NSAlert()
        alert.messageText = "警告消息⚠️"
        alert.informativeText = "警告消息⚠️的描述"
        alert.addButton(withTitle: "确定")
        alert.addButton(withTitle: "隐藏")
        alert.addButton(withTitle: "取消")

runModal方法,警告栏是独立在window外部

        let result = alert.runModal()
        switch result {
        case .alertFirstButtonReturn:
            print("确定")
        case .alertSecondButtonReturn:
            print("隐藏")
        case .alertThirdButtonReturn:
            print("取消")
        default:
            break
        }

效果:

beginSheetModal方法,使警告栏在window内部

        alert.beginSheetModal(for: view.window!) { (response) in
            print("选择了\"\(response)\"")
        }

效果:

2.自动化测试UI

NSAlertViewUITests.swift

效果图:

可以测试后加入XCTAssert(window.staticTexts["确定"].exists),可以测试通过

其实UITests自动化测试UI,自己在项目中接触的不多,在这里记录并尝试一下

3.单元测试

创建Song.swift模型,里面有属性title,author,duration

class Song: NSObject {
    
    var title: String
    var author: String
    var duration: Double
    
    init(title: String, author: String, duration: Double) {
        self.title = title
        self.author = author
        self.duration = duration
    }
}

创建Constants.swift储存一些常量来进行测试

class Constants: NSObject {
    static let title = "Great Title"
    static let author = "MySelf"
    static let duration = 60.0
}

创建SongTests.swift需要继承于XCTestCase

import XCTest

// 需要导入整个项目名称NSAlertView
@testable import NSAlertView

class SongTests: XCTestCase {
    
    func textInit() {
        let song = Song(title: Constants.title, author: Constants.author, duration: Constants.duration)
        
        XCTAssertEqual(song.title, Constants.title)
        XCTAssertEqual(song.author, Constants.author)
        XCTAssertEqual(song.duration, Constants.duration)
    }
}

点击测试测试通过,证明构造方法的结果和模型结果一致
