Question

我正在尝试使用XCode 7.2的iOS新UI测试框架。

我已经按照一些教程观看了Apple的演示视频并试图录制一些测试用例。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Apple的iPhoneCoreDataRecipes演示应用程序开始处理简单和“验证”的问题。

下面的简单测试类：

#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？有关如何调试问题的任何想法？我是否需要“以某种方式”启用该设备？

更新＃1

当我尝试在设备中运行测试用例时，我会在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尝试加载应用程序而是黑屏

此外，当我尝试重新编码时，Xcode会发生以下崩溃：

Answer 1

我在黑暗中最好的一击：

IOS 8增强

iOS 8在“设置”＆gt;下包含一个新的“启用UI自动化”首选项开发人员，允许第三方开发人员更好地控制他们的设备何时可用于执行自动化。对于物理iOS设备，默认情况下此设置处于关闭状态，必须在执行任何UI自动化之前启用此设置。在模拟器中，默认情况下启用该设置。

Source

这是在更明显的要求之上（ios9目标，10.10 / 11等）。该文档还列出了一些您可能会发现有助于参考的其他要求和链接。

Answer 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。

使用XCode 7.2录制时，XCUITest崩溃
