Why is my object's weak delegate property nil in my unit tests?

Question

I have a pretty simple setup for this unit test. I have a class that has a delegate property:

@interface MyClass : NSObject
...
@property (nonatomic, weak) i         


        

Answer 1

A workaround is to use Partial Mocks.

@interface TestMyDelegateProtocolDelegate : NSObject 
@end

@implementation TestMyDelegateProtocolDelegate
- (void)someMethod {}
@end


@implementation SomeTest {
- (void)testMyMethod_WithDelegate {
  id delegate = [[TestMyDelegateProtocolDelegate] alloc] init];
  id delegateMock = [OCMockObject partialMockForObject:delegate]
  [[[delegateMock expect] someMethod]
  myClassIvar.connectionDelegate = delegate;
  [myClass someOtherMethod];
  STAssertNoThrow([delegate verify], @"should have called someMethod on delegate.");
}
@end
