Unit Testing in xcode(Using GHUnit and OCMock)

Question

In xcode,I am trying to do unit Testing using GHUnit and OCMock as described here :

Unit Testing Xcode

And Set Up methods as descibed here :

GHUnitTestCase

But got the error in this method

• (void)setUpClass { }

when I initialize my ViewController Object as below :

#import <GHUnitIOS/GHUnit.h>
#import <OCMock/OCMock.h>
#import "RS_LoginRSViewController.h"

@interface SampleLibTest : GHTestCase
{
  RS_LoginRSViewController * login;
}
@end

@implementation SampleLibTest

// Run before each test method
- (void)setUp { }

// Run after each test method
- (void)tearDown { }

// Run before the tests are run for this class
- (void)setUpClass
{
 GHTestLog(@"Log with a test with the GHTestLog(...) for test specific logging.");
 login = [[RS_LoginRSViewController alloc]init];
}

// Run before the tests are run for this class
 - (void)tearDownClass { }

// Tests are prefixed by 'test' and contain no arguments and no return value
 - (void)testA {
 GHTestLog(@"Log with a test with the GHTestLog(...) for test specific logging.");
 }

 // Override any exceptions; By default exceptions are raised, causing a test failure
  - (void)failWithException:(NSException *)exception { }
 @end

But got error as Apple Mach-O Linker Error :

Undefined symbols for architecture i386: "_OBJC_CLASS_$_RS_LoginRSViewController", referenced from: objc-class-ref in SampleTestCase.o ld: symbol(s) not found for architecture i386 clang: error: linker command failed with exit code 1 (use -v to see invocation)

But when I remove line

     login = [[RS_LoginRSViewController alloc]init];

from

- (void)setUpClass

method then It runs successfully.Why I am getting this error ? Any help will be appreciated.

I resolved errors by adding necessary files , frameworks and library to build phases of project target of testing.
