【问题描述】：

我正在使用 Xcode 7.2 试验新的 ios UI 测试框架。

我遵循了一些教程并观看了 Apple 的演示视频并尝试记录一些测试用例。当目标是“模拟器”时，第一次测试成功。当我尝试在真实设备中重复这些步骤时，Xcode 在启动应用程序后立即崩溃。我使用了来自 Apple 的 iPhoneCoreDataRecipes 演示应用程序，以便开始使用一些简单且“经过验证”的东西。

下面是一个简单的测试类：

#import <XCTest/XCTest.h>

@interface RecipesUITests : XCTestCase

@end

@implementation RecipesUITests

- (void)setUp 
    [super setUp];

    // 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.
    self.continueAfterFailure = NO;
    // UI tests must launch the application that they test. Doing this in setup will make sure it happens for each test method.
    [[[XCUIApplication alloc] init] launch];

    // 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.


- (void)tearDown 
    // Put teardown code here. This method is called after the invocation of each test method in the class.
    [super tearDown];


- (void)testExample 
    // Use recording to get started writing UI tests.
    // Use XCTAssert and related functions to verify your tests produce the correct results.


    XCUIApplication *app = [[XCUIApplication alloc] init];
    [app.navigationBars[@"Recipes"].buttons[@"Add"] tap];
    [app.textFields[@"Recipe Name"] typeText:@"Lef"];
    [app.navigationBars[@"Add Recipe"].buttons[@"Save"] tap];

    XCUIElementQuery *tablesQuery = app.tables;
    XCUIElement *descriptionTextField = tablesQuery.textFields[@"Description"];
    [descriptionTextField tap];
    //[descriptionTextField tap];
    //[descriptionTextField tap];

    XCUIElement *lefNavigationBar = app.navigationBars[@"Lef"];
    [lefNavigationBar.buttons[@"Edit"] tap];

    XCUIElement *overviewTextField = tablesQuery.textFields[@"Overview"];
    [overviewTextField tap];
    //[overviewTextField typeText:@"Lef2"];
    [lefNavigationBar.buttons[@"Done"] tap];
    [lefNavigationBar.buttons[@"Recipes"] tap];

这是一个已知问题吗？关于如何调试问题的任何想法？我需要“以某种方式”来启用设备吗？

更新 #1

当我尝试在设备中运行测试用例时，我在 Xcode 中收到了一些日志。

看起来什么都没有发生，没有执行测试用例，Xcode 尝试加载应用程序但它显示黑屏。

此外，当我尝试重新编码时，Xcode 会导致以下崩溃：

我在黑暗中的最佳拍摄：

IOS 8 增强

iOS 8 在设置 > 开发人员下包含一个新的启用 UI 自动化首选项，它允许第三方开发人员更好地控制他们的设备何时可以执行自动化。对于物理 iOS 设备，此设置默认关闭，必须在执行任何 UI 自动化之前启用。在模拟器中，该设置默认开启。

Source

这是在更明显的要求（ios9 目标、10.10/11 等）之上的。该文档还列出了许多其他要求和链接，您可能会发现对参考有帮助。

【讨论】：

很遗憾没有。我启用了该选项，但行为相同。

重启手机后，好像可以了。也许这可以补充您的答案。

@cateof 并不是说​​ Louis 的回答没有帮助，但我发现很多 Xcode 的 UI 测试错误可以通过重新启动设备或通过 Xcode > Devices 删除应用程序并重新安装来解决（对于例如，当你运行一个 UI 测试并且它给你“成功”，甚至没有运行任何东西，或者记录我也经历过的崩溃）

@JamesGoe 我接受了这个答案，因为它是在黑暗中拍摄的，当然我在我的设备中关闭了这个选项。当然，这还不够。正如我在我的 cmets 中所写，设备重启是强制性的。

这对我有用 - iOS 7.2，打开启用 UI 自动化，然后重新启动 iOS 设备。我的 iOS 设备是 iPhone 6 PLUS。如果重新打开设备电源时 Xcode 中未正确识别设备，则断开 USB 电缆与设备的连接并重新应用 - 如果 Xcode 现在可以正确看到设备，那么 RECORD UI 测试功能现在应该可以正常工作而不会导致 Xcode 崩溃。 -rrh

【参考方案2】：

确认启用 UI 自动化和电源循环设备确实允许 Apple 的 UI 测试在真实设备上运行。在 Xcode 8 + iOS 10.1 上测试。
