GHUnit Linker Error with Application Classes

Question

I am trying to run the GHUnit test to just verify that the setter really works for the NSManagedObject in my application. My application is called “Machine”, and my goal of GHUnit is called “Tests”. I added the Machine as a function of the testing purpose. My object in the test is called Target. The code is below, 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

Undefined symbols for i386 architecture: "_OBJC_CLASS _ $ _ Target" referenced: objc-class-ref in ControllerTests.o ld: symbol not found for i386 architecture collect2: ld returned 1 exit status

Answer 1

Temporary solution:

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

I'm confused too. I feel like this is crazy. Same: Communication error for unit testing with Xcode 4?

Answer 2

A better solution would be to duplicate the target when creating one for the GHUnit test instead of creating a new target.
