GHUnit Linker Error with App Classes

Question

I'm trying to run a GHUnit test to just test that a setter actually works for a NSManagedObject object in my app. My app is called Machine and my GHUnit target is called Tests. I've added Machine as a dependency to the Tests target. My object in the test is called Goal. Here is the code and the error in the Link is shown below.

#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);

}

@end

Answer 1

A temporary solution:

Select target "Tests". Select "Compile Sources". Then add "Goal.m", you will run tests.

I'm also confused. I feel this is crazy. Same:Linking error for unit testing with XCode 4?

Answer 2

A better solution might be to duplicate target while creating one for GHUnit test instead of creating a new target.
