XCUITest 类拆解不会删除应用程序.但是如果它的实例拆解就可以了.我究竟做错了什么? [英] XCUITest Class teardown isnt deleting the app. But works if its instance teardown. What am I doing wrong?

问题描述

我有一个试图删除应用程序的类拆解，但它无法识别 app.terminate().

I have a class teardown which is trying to remove the app, but it doesn't recognize app.terminate().

class DeviceSettingsUtilities : UITestUtilities {
func removeApp(productName:String){
        print("in teardown")
        let springboard = XCUIApplication(bundleIdentifier: "com.apple.springboard")
        XCUIApplication().terminate() // this does nothing
        XCUIApplication(bundleIdentifier: "com.xxx.xxxx").terminate()//this does nothing too, but this works when called as an instance teardown
        sleep(5)
        springboard.activate()
        let icon = springboard.icons.matching(identifier: productName).firstMatch
// icon.exists is false when called as a class teardown
// icon.exists is true when called as an instance teardown
        if icon.exists {
            let iconFrame = icon.frame
            let springboardFrame = springboard.frame
            icon.press(forDuration:1.3)
            springboard.coordinate(withNormalizedOffset: CGVector(dx: ((iconFrame.minX + 3) / springboardFrame.maxX), dy:((iconFrame.minY + 3) / springboardFrame.maxY))).tap()
            sleep(5)
            springboard.buttons["Delete"].firstMatch.tap()
            sleep(5)
        }
        XCUIApplication().terminate()
    }

}

这是在测试用例类拆解方法中调用的，如下所示

This is being called in the test case class teardown method as shown below

override class func tearDown() {
    super.tearDown()
    let deviceSettings = DeviceSettingsUtilities()
    deviceSettings.removeApp(productName: ProductName.rawValue)
}

这只是不会删除应用程序，但是如果我将类 func tearDown() 更改为 func tearDown() ，它会毫无问题地删除应用程序.不知道我错过了什么.有什么建议吗?

This just doesnt delete the app, But if i change class func tearDown() to func tearDown() , it deletes the app with no problem. Not sure what i am missing. Any suggestions ?

推荐答案

这似乎是最新 Xcode 10 中的一个错误.当声明为 class 时，XCUIApplication.terminate() 似乎在 tearDown() 中不起作用.

This seems like a bug in latest Xcode 10. XCUIApplication.terminate() doesn't seem to work in tearDown() when declared as class.

这可以通过两种方式解决:

This can be solved in two ways:

第一个选项是使用:

override func tearDown() {
    XCUIApplication().terminate()
    super.tearDown()
}

代替:

override class func tearDown() {…} 

或者，以不同的方式终止应用程序(按主页按钮，打开不同的应用程序...).但是，我会使用第一种方式.

Or, terminate the app differently (press home button, open different app...). However, I would use the first way.

还可以考虑向 Apple 报告此问题，以便他们解决.

Also consider reporting this to Apple, so they can fix it.

这与应用程序状态(XCUIApplication().state.rawValue)无关，因为它在测试和 tearDown() 中是相同的(4 = 运行前台).另外 - 官方文档说 .terminate() 将终止应用程序，该应用程序与 Xcode 有一个调试会话，但调试会话在 tearDown() 中也处于活动状态.所以这很可能是 Xcode 中的一个错误.

This has nothing to do with app state (XCUIApplication().state.rawValue), since it is same in test and in tearDown() (4 = running foreground). Also - official documentation says that .terminate() will terminate app, which has a debug session with Xcode, but the debug session is active in tearDown() as well. So it is really probably a bug in Xcode.
