应用程序类的 GHUnit 链接器错误答案

【问题描述】：

我正在尝试运行 GHUnit 测试来测试 setter 是否确实适用于我的应用程序中的 NSManagedObject 对象。我的应用程序称为 Machine，我的 GHUnit 目标称为 Tests。我已将 Machine 添加为 Tests 目标的依赖项。我在测试中的对象称为目标。这是代码，链接中的错误如下所示。

#import <GHUnitIOS/GHUnit.h>
#import <CoreData/CoreData.h>
#import "Goal.h"
#import "GoalRec.h"

@interface ControllerTests : GHTestCase { }
@property (retain) Goal *goal;
@end

@implementation ControllerTests
@synthesize goal;

- (BOOL)shouldRunOnMainThread {
// By default NO, but if you have a UI test or test dependent on running on the main    thread return YES
return NO;
}

- (void)setUpClass {
    // Run at start of all tests in the class
}

- (void)tearDownClass {
    // Run at end of all tests in the class
}

- (void)setUp {
    // Run before each test method
    self.goal = [[[Goal alloc] init] autorelease];
}

- (void)tearDown {
    // Run after each test method
    self.goal = nil;   // prevents memory leak
}  

- (void)testImageArray {

    NSString *str = @"Hello";
    Goal *obj = self.goal;
    obj.goal = str;
    GHAssertEqualStrings(obj.goal, @"Hello", nil);

}

@结束

【解决方案1】：

临时解决方案：

选择目标“测试”。选择“编译源”。然后添加“Goal.m”，您将运行测试。

我也很困惑。我觉得这很疯狂。同：Linking error for unit testing with XCode 4?

【解决方案2】：

更好的解决方案可能是在为 GHUnit 测试创建目标时复制目标，而不是创建新目标。
