xcode - 如何使用 XCTest 从 iOS 13 删除/重置应用程序？

Question

最近我开始使用XCTest测试一个iOS应用，但发现了一些困难，主要的困难是删除或重置每个测试类中的应用内容。

我目前正在使用 XCode 11 并尝试从 iOS 13 中删除/重置每个测试类的应用程序，我已经尝试过:

通过跳板删除应用

通过转到应用程序设置删除应用程序

这一步在我的测试中非常重要，因为在每个测试中我都需要创建一个配置文件并登录，所以在下一个测试中我需要从头开始安装应用程序

import XCTest

let springboard = XCUIApplication(bundleIdentifier: "com.apple.springboard")

func deleteMyApp() {
    XCUIApplication().terminate()

    let bundleDisplayName = "MyApp"

    let icon = springboard.icons[bundleDisplayName]
    if icon.exists {
        icon.press(forDuration: 1)

        let buttonRemoveApp = springboard.buttons["Remove App"]
        if buttonRemoveApp.waitForExistence(timeout: 5) {
            buttonRemoveApp.tap()
        } else {
            XCTFail("Button \"Remove App\" not found")
        }

        let buttonDeleteApp = springboard.alerts.buttons["Delete App"]
        if buttonDeleteApp.waitForExistence(timeout: 5) {
            buttonDeleteApp.tap()
        }
        else {
            XCTFail("Button \"Delete App\" not found")
        }

        let buttonDelete = springboard.alerts.buttons["Delete"]
        if buttonDelete.waitForExistence(timeout: 5) {
            buttonDelete.tap()
        }
        else {
            XCTFail("Button \"Delete\" not found")
        }
    }
}

class HomeUITests: XCTestCase {
    override func setUpWithError() throws {
        // Put setup code here. This method is called before the invocation of each test method in the class.

        // In UI tests it is usually best to stop immediately when a failure occurs.
        continueAfterFailure = false

        // In UI tests it’s important to set the initial state - such as interface orientation - required for your tests before they run. The setUp method is a good place to do this.
    }

    override func tearDownWithError() throws {
        // Put teardown code here. This method is called after the invocation of each test method in the class.
    }

    func testExample() throws {
        deleteMyApp()

        // UI tests must launch the application that they test.
        let app = XCUIApplication()
        app.launch()

        // Use recording to get started writing UI tests.
        // Use XCTAssert and related functions to verify your tests produce the correct results.
    }

    func testLaunchPerformance() throws {
        if #available(macOS 10.15, iOS 13.0, tvOS 13.0, *) {
            // This measures how long it takes to launch your application.
            measure(metrics: [XCTApplicationLaunchMetric()]) {
                XCUIApplication().launch()
            }
        }
    }
