iOS KIF 测试失败

Question

我正在尝试在示例应用中使用 KIF 学习自动化 UI 测试。我的简单测试不断失败。我的代码:

#import <XCTest/XCTest.h>
#import <KIF/KIF.h>

@interface AutomatedUITestsSampleUITests : KIFTestCase

@end

@implementation AutomatedUITestsSampleUITests

- (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 {

    [tester waitForViewWithAccessibilityLabel:@"LOGIN - Button"];

    [tester tapViewWithAccessibilityLabel:@"LOGIN - Button" traits:UIAccessibilityTraitButton];
}

我已将辅助功能标签 LOGIN - Button 设置为 Storyboard中的 UIButton，同时辅助功能已启用。

我在控制台中得到这个:

Test Case '-[AutomatedUITestsSampleUITests testExample]' started.
    t =     0.00s     Start Test at 2017-06-16 13:45:07.071
    t =     0.00s     Set Up
    t =     0.04s         Launch com.UITests.AutomatedUITestsSample
    t =     4.63s             Waiting for accessibility to load
    t =     8.77s             Wait for app to idle
    t =    10.48s     Tear Down
Test Case '-[AutomatedUITestsSampleUITests testExample]' failed (10.868 seconds).

这是一个非常简单的测试。为什么会失败？提前致谢。

如果您有权访问 XCUIApplication，则您的项目配置有问题。 KIF 测试目标应该是“单元测试目标”，而不是“UI 测试目标”。如果配置正确，则无需启动应用程序(也不可能进行应用程序启动操作)——它会在单元测试开始时启动。当您使用 UI 测试目标时，您的测试在单独的进程中运行，并且 KIF 无权访问您的应用。

我建议使用 this guide 再次配置您的测试目标
