有没有办法在 Swift XCTest UI 的测试之间重置应用程序？

XCTest 中是否有 API 调用，我可以将其放入 setUP() 或tearDown() 中以在测试之间重置应用程序？我查看了 XCUIApplication 的点语法，我看到的只是 .launch()

或者有没有办法在 Swift 中调用 shell 脚本？然后我可以在测试方法之间调用 xcrun 来重置模拟器。

You can add a "Run Script" phase to build phases in your test target to uninstall the app before running unit tests against it, unfortunately this is not between test cases, though.

/usr/bin/xcrun simctl uninstall booted com.mycompany.bundleId

Update

在测试之间，您可以删除该应用程序在拆卸阶段通过跳板。尽管如此，这确实需要使用 XCTest 的私有标头。 （标头转储可从Facebook 的 WebDriverAgent 在这里 https://github.com/facebook/WebDriverAgent/tree/master/PrivateHeaders/XCTest.)

以下是 Springboard 类中的一些示例代码，用于通过点击并按住从 Springboard 删除应用程序：

#斯威夫特 4：

import XCTest

class Springboard {

    static let springboard = XCUIApplication(bundleIdentifier: "com.apple.springboard")
    
    /**
     Terminate and delete the app via springboard
     */
    class func deleteMyApp() {
        XCUIApplication().terminate()
        
         // Force delete the app from the springboard
        let icon = springboard.icons["Citizen"]
        if icon.exists {
            let iconFrame = icon.frame
            let springboardFrame = springboard.frame
            icon.press(forDuration: 1.3)
        
            // Tap the little "X" button at approximately where it is. The X is not exposed directly
            springboard.coordinate(withNormalizedOffset: CGVector(dx: (iconFrame.minX + 3) / springboardFrame.maxX, dy: (iconFrame.minY + 3) / springboardFrame.maxY)).tap()
        
            springboard.alerts.buttons["Delete"].tap()
        }
    }
 }

#斯威夫特 3-：

import XCTest

class Springboard {

    static let springboard = XCUIApplication(privateWithPath: nil, bundleID: "com.apple.springboard")
    
    /**
     Terminate and delete the app via springboard
     */
    class func deleteMyApp() {
        XCUIApplication().terminate()
        
        // Resolve the query for the springboard rather than launching it
        springboard.resolve()
        
        // Force delete the app from the springboard
        let icon = springboard.icons["MyAppName"]
        if icon.exists {
            let iconFrame = icon.frame
            let springboardFrame = springboard.frame
            icon.pressForDuration(1.3)
            
            if #available(iOS 13.0, *) {
                springboard.buttons["Remove App"].tap()
                springboard.alerts.buttons["Delete App"].tap()
                springboard.alerts.buttons["Delete"].tap()
            } else {
            
                // Tap the little "X" button at approximately where it is. The X is not exposed directly
                let xPosition = CGVector(dx: (iconFrame.minX + 3) / springboardFrame.maxX,
                                     dy: (iconFrame.minY + 3) / springboardFrame.maxY)
                springboard.coordinate(withNormalizedOffset: xPosition).tap()
                springboard.alerts.buttons["Delete"].tap()
            }
        }
    }
 }

进而：

override func tearDown() {
    Springboard.deleteMyApp()
    super.tearDown()
}

私有标头已导入到 Swift 桥接标头中。您需要导入：

// Private headers from XCTest
#import "XCUIApplication.h"
#import "XCUIElement.h"

Note：从 Xcode 10 开始，XCUIApplication(bundleIdentifier:)现在由Apple公开，私有标头是不再需要.
