有沒有辦法在Xcode 7中的Swift XCTest UI中的測試之間重置應用程序？

Question

XCTest中是否有API調用，我可以放入setUP（）或tearDown（）來重置測試之間的應用程序？我查看了XCUIApplication的點語法，我只看到了.launch（）

或者有沒有辦法在Swift中調用shell腳本？然後我可以調用xcrun中間的測試方法來重置模擬器。

Answer 1

此時，在Xcode 7 & 8的公共API和模擬器不出現具有從setUp()和tearDown()XCText可調用子類的任何方法，以「復位內容和設置」模擬器。

存在使用公共API其他可能的方法：

1. 應用代碼。添加一些myResetApplication()應用程序代碼以使應用程序處於已知狀態。但是，設備（模擬器）狀態控制受應用程序沙箱的限制......在應用程序之外沒有太多幫助。這種方法對於清除應用程序可控持久性是可以的。

2. Shell腳本。從shell腳本運行測試。在每次測試運行之間使用xcrun simctl erase all或xcrun simctl uninstall <device> <app identifier>或類似軟件重置模擬器（或卸載應用程序）。 see StackOverflow: "How can I reset the iOS Simulator from the command line?"

macos> xcrun simctl --help 
    # can uninstall a single application 
    macos> xcrun simctl uninstall --help 
    # Usage: simctl uninstall <device> <app identifier> 

Xcode的模式動作。添加xcrun simctl erase all（或xcrun simctl erase <DEVICE_UUID>）或類似的計劃測試部分。選擇產品>計劃>編輯計劃...菜單。展開Scheme測試部分。選擇測試部分下的預先操作。點擊（+）添加「新建腳本動作」。命令xcrun simctl erase all可以直接輸入，而不需要任何外部腳本。用於調用1.應用程序代碼重置應用

選項：

A. 應用程序UI。 [用戶界面測試]提供重置按鈕或其他UI操作來重置應用程序。 UI元素可以通過XCTest例程setUp()，tearDown()或testSomething()中的XCUIApplication來行使。

B. 啓動參數。 [UI試驗]如由Victor羅寧所指出的，一個參數可以從測試setUp()傳遞...

class AppResetUITests: XCTestCase { 

    override func setUp() { 
    // ... 
    let app = XCUIApplication() 
    app.launchArguments = ["MY_UI_TEST_MODE"] 
    app.launch() 

...由AppDelegate接收...

class AppDelegate: UIResponder, UIApplicationDelegate { 

    func application(…didFinishLaunchingWithOptions…) -> Bool { 
    // ... 
    let args = NSProcessInfo.processInfo().arguments 
    if args.contains("MY_UI_TEST_MODE") { 
     myResetApplication() 
    } 

C. Xcode方案參數。[UI測試，單元測試]選擇產品>方案>編輯方案...菜單。展開Scheme Run部分。 （+）添加一些參數，如MY_UI_TEST_MODE。該參數將在NSProcessInfo.processInfo()中提供。

// ... in application 
let args = NSProcessInfo.processInfo().arguments 
if args.contains("MY_UI_TEST_MODE") { 
    myResetApplication() 
} 

Z. 直接呼叫。 [單元測試]單元測試包被注入到正在運行的應用程序中，並可以直接在應用程序中調用一些myResetApplication()例程。警告：默認單元測試在主屏幕加載後運行。 see Test Load Sequence但是，UI測試包作爲被測試應用程序的外部進程運行。所以，單元測試中的工作會在UI測試中出現鏈接錯誤。

class AppResetUnitTests: XCTestCase { 

    override func setUp() { 
    // ... Unit Test: runs. UI Test: link error. 
    myResetApplication() // visible code implemented in application 

Answer 2

你可以問問你的應用程序，以 「清理」 本身

• 您使用XCUIApplication.launchArguments設置一些標誌

• 在AppDelegate中您檢查

  如果NSProcessInfo.processInfo（）。 arguments.contains（「YOUR_FLAG_NAME_HERE」）{ //在這裏做一個清理 }

Answer 3

不幸的是，這不在測試用例之間，雖然，但在運行單元測試之前卸載應用程序，您可以添加「運行腳本」階段以構建測試目標階段。

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

測試之間，你可以通過在拆卸階段的跳板刪除的應用。雖然，這確實需要使用來自XCTest的私有頭文件。 （報頭轉儲可從Facebook's WebDriverAgent here。）

下面是從一個跳板類一些示例代碼經由抽頭從跳板刪除應用和保持：

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) 

      // Tap the little "X" button at approximately where it is. The X is not exposed directly 
      springboard.coordinateWithNormalizedOffset(CGVectorMake((iconFrame.minX + 3)/springboardFrame.maxX, (iconFrame.minY + 3)/springboardFrame.maxY)).tap() 

      springboard.alerts.buttons["Delete"].tap() 
     } 
    } 
} 

然後：

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

私有頭文件被導入Swift橋接頭文件中。你需要導入：

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

我用@Chase荷蘭answer和更新的跳板類遵循相同的方法來重新使用設置應用程序的內容和設置。這在您需要重置權限對話框時非常有用。

 
import XCTest 

class Springboard { 
    static let springboard = XCUIApplication(privateWithPath: nil, bundleID: "com.apple.springboard") 
    static let settings = XCUIApplication(privateWithPath: nil, bundleID: "com.apple.Preferences") 

    /** 
    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) 

      // Tap the little "X" button at approximately where it is. The X is not exposed directly 
      springboard.coordinateWithNormalizedOffset(CGVectorMake((iconFrame.minX + 3)/springboardFrame.maxX, (iconFrame.minY + 3)/springboardFrame.maxY)).tap() 

      springboard.alerts.buttons["Delete"].tap() 

      // Press home once make the icons stop wiggling 
      XCUIDevice.sharedDevice().pressButton(.Home) 
      // Press home again to go to the first page of the springboard 
      XCUIDevice.sharedDevice().pressButton(.Home) 
      // Wait some time for the animation end 
      NSThread.sleepForTimeInterval(0.5) 

      let settingsIcon = springboard.icons["Settings"] 
      if settingsIcon.exists { 
       settingsIcon.tap() 
       settings.tables.staticTexts["General"].tap() 
       settings.tables.staticTexts["Reset"].tap() 
       settings.tables.staticTexts["Reset Location & Privacy"].tap() 
       settings.buttons["Reset Warnings"].tap() 
       settings.terminate() 
      } 
     } 
    } 
} 

Answer 5

更新爲swift 3.1/xcode 8。3

在測試目標創建橋接報頭：

#import <XCTest/XCUIApplication.h> 
#import <XCTest/XCUIElement.h> 

@interface XCUIApplication (Private) 
- (id)initPrivateWithPath:(NSString *)path bundleID:(NSString *)bundleID; 
- (void)resolve; 
@end 

更新跳板類

class Springboard { 
    static let springboard = XCUIApplication(privateWithPath: nil, bundleID: "com.apple.springboard")! 
    static let settings = XCUIApplication(privateWithPath: nil, bundleID: "com.apple.Preferences")! 

/** 
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}"] /// change to correct app name 
    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() 

    // Press home once make the icons stop wiggling 

    XCUIDevice.shared().press(.home) 
    // Press home again to go to the first page of the springboard 
    XCUIDevice.shared().press(.home) 
    // Wait some time for the animation end 
    Thread.sleep(forTimeInterval: 0.5) 

     let settingsIcon = springboard.icons["Settings"] 
     if settingsIcon.exists { 
     settingsIcon.tap() 
     settings.tables.staticTexts["General"].tap() 
     settings.tables.staticTexts["Reset"].tap() 
     settings.tables.staticTexts["Reset Location & Privacy"].tap() 
     settings.buttons["Reset Warnings"].tap() 
     settings.terminate() 
     } 
    } 
    } 
    }

我用@ODManswer，但修改它用於夫特4. NB工作：一些S/O答案沒有區分Swift版本，這些版本有時具有相當根本性的差異。我已經在iPhone 7模擬器和iPad Air模擬器上進行了縱向測試，並且適用於我的應用。

Answer 7

對於iOS模擬遊戲11的時候，我做了曾經如此輕微的修改，以挖掘「X」圖標，在這裏我們每修復@code猴建議挖掘。 Fix在10.3和11.2手機模擬器上運行良好。爲了記錄，我使用了swift 3.以爲我會通過一些代碼複製和粘貼以更輕鬆地找到修復。 :)

import XCTest 

class Springboard { 

    static let springboard = XCUIApplication(privateWithPath: nil, bundleID: "com.apple.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["My Test App"] 
     if icon.exists { 
      let iconFrame = icon.frame 
      let springboardFrame = springboard!.frame 
      icon.press(forDuration: 1.3) 

      springboard!.coordinate(withNormalizedOffset: CGVector(dx: (iconFrame.minX + 3 * UIScreen.main.scale)/springboardFrame.maxX, dy: (iconFrame.minY + 3 * UIScreen.main.scale)/springboardFrame.maxY)).tap() 

      springboard!.alerts.buttons["Delete"].tap() 
     } 
    } 
}
