ios - 使用 Xcode 7.2 录制时 XCUITest 崩溃

Question

我正在使用 Xcode 7.2 尝试新的 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，第一次测试成功了。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。我用了iPhoneCoreDataRecipes来自 Apple 的演示应用程序，以便开始使用简单且“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？关于如何调试问题有什么想法吗？我需要“以某种方式”来启用该设备吗？

更新#1

当我尝试在设备中运行测试用例时，我在 Xcode 中收到一些日志。

看起来没有任何反应，没有执行测试用例，Xcode 尝试加载应用程序，但显示黑屏。

此外，当我尝试重新编码 Xcode 时，会出现以下崩溃:

IOS 8 ENHANCEMENT

iOS 8 includes a new Enable UI Automation preference under Settings > Developer, which allows third-party developers finer control of when their devices are available to perform automation. For physical iOS devices, this setting is off by default and must be enabled prior to performing any UI Automation. In the simulator, the setting is enabled by default.
