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

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