cocoa - 使用多个 XCTestCase 类进行 UITesting

Question

我正在为我的项目编写 UITest 案例。因此，我希望将多个文件子类化到 XCTestCase 或子类化到我的其他测试类。每当我创建这样的文件时，我都会收到以下错误。

duplicate symbol _lastUsedSaveDirectory in:
/Users/UserName/Library/Developer/Xcode/DerivedData/ProjectName/Build/Intermediates/CodeCoverage/Intermediates/Project.build/Debug/Project_UITests.build/Objects-normal/x86_64/SecondaryFile.o
/Users/UserName/Library/Developer/Xcode/DerivedData/ProjectName/Build/Intermediates/CodeCoverage/Intermediates/Project.build/Debug/Project_UITests.build/Objects-normal/x86_64/MainFile.o
ld: 1 duplicate symbol for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)

我尝试了以下方法，但没有任何效果:

1. Created "SecondaryFile" by subclassing it from "MainFile" which is a subclass of "XCTestCase".
2. Created "SecondaryFile" by subclassing it directly from "XCTestCase".
3. Created both .h and .m file for both the "MainFile" and "SecondaryFile"

主文件.m

#import <XCTest/XCTest.h>

@interface MainFile_UITests : XCTestCase
@end

@implementation MainFile_UITests

- (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.    
}

@end

次要文件.m

#import <XCTest/XCTest.h>

@interface SecondaryFile_UITests : XCTestCase
@end

@implementation SecondaryFile_UITests

- (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];
}

@end

有人可以告诉我如何模块化/创建多个文件 UITesting 类。

Answer 1

为了使用多个 UI 测试文件，您应该首先为 UITests.m 创建一个头文件。 ，然后在您单独的测试文件中，继承自 UITest.h .这将为您提供 setUp和 tearDown来自 UITests.m 的方法在你的子类中。然后，您所要做的就是将新的测试方法添加到您的子类中。

例如，下面是 Objective-C 中的子类 UITests 文件的示例:
