ios - 如何使用 XCTest 在以编程方式添加的 UIView 上测试 UILabel

Question

我想测试我的 dashboardLabel 的 .text，但我不知道如何通过 XCTest 访问它。

DashboardView.swift 看起来像这样:

import UIKit

class DashBoardView: UIView {

override init(frame: CGRect) {
    super.init(frame: frame)

    createSubviews()
}

required init?(coder aDecoder: NSCoder) {
    super.init(coder: aDecoder)
    fatalError("init(coder:) has not been implemented")
}

// MARK: - Create Subviews

func createSubviews() {
    backgroundColor = .white

    var dashboardLabel : UILabel

    dashboardLabel = {
        let label = UILabel()
        label.text = "Dashboard Label"
        label.textColor = .black
        label.frame = CGRect(x:60, y:80, width: 200, height: 30)
        label.backgroundColor = .green
        label.backgroundColor = .lightGray
        label.font = UIFont(name: "Avenir-Oblique", size: 13)
        label.textAlignment = .center
        return label
    }()

}

DashboardViewController.swift 看起来像这样:

import UIKit

class DashBoardViewController: UIViewController {

    var dashboardview = DashBoardView()

    //MARK: View Cycle
    override func loadView() {
         view = dashboardview
    }

    override func viewWillAppear(_ animated: Bool) {
        super.viewWillAppear(animated)
    }

    override func viewDidLoad() {
        super.viewDidLoad()

        title = "DashBoard"
    }

    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
    }

}

我知道如何测试 DashboardViewController.swift 的标题

import XCTest
@testable import DashBoard

class DashBoardTests: XCTestCase {
    func test_if_title_is_DashBoard() {

    let vc = DashBoardViewController()
    let _ = vc.view
    XCTAssertEqual(vc.navigationItem.title, "Dashboard")
}

但我完全不知道如何访问 DashBoardView.swift 上的 dashboardLabel。

我希望这能解释我的问题，你们中的任何人都可以帮助我，或者为我指明正确的方向!

谢谢✌️

您可以使用 accessibilityIdentifier 来做到这一点
