应用程序类的GHUnit链接器错误

Question

我正试图运行GHUnit测试，以测试setter是否真的适用于我的应用程序中的NSManagedObject对象。我的应用程序名为Machine，我的GHUnit目标名为Tests。我已经将Machine添加为测试目标的依赖项。我在测试中的对象叫做Goal。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

Answer 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。我觉得这太疯狂了。相同：XCode 4单元测试的链接错误？

Answer 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。
