How to get the mocked value when calling isKindOfClass for an OCMock object?

Passing an OCMock object to a method where the function calls isKindOfClass. However for unit test, the value returned is not of the mocked class but OCMockObject

If you want to pass OCMock object to a method where the function calls isKindOfClass you need to create partial mock. Following code might help you. It worked for me.

-(void)testMyTest
{
    FirstViewController* masterVC = [[FirstViewController alloc]init];
    SecondViewController *second = [[SecondViewController alloc] init];
    id master = [OCMockObject partialMockForObject:second];
    [[master expect] getName:@"PARAM"];
    [masterVC doSomething:master];
    [master verify];

    [masterVC release];
    [second release];
}

doSomething method inside FirstViewController

-(void)doSomething:(SecondViewController *)detail
{
    if ([detail isKindOfClass:[SecondViewController class]])
    {
        NSString * returnVal = [detail getName:@"PARAM"];
        NSLog(@"returnVal %@",returnVal);
    }
}

One more alternative is mocking the isKindOfClass method, So the test case will become

- (void)testMyTest
{
     CalculatorViewController* masterVC = [[CalculatorViewController alloc]init];
     id master = [OCMockObject niceMockForClass:[SecondViewController class]];
     BOOL ret = YES;
     [[[master expect] andReturnValue:OCMOCK_VALUE(ret)] isKindOfClass:[SecondViewController class]];
     [[master expect] getName:@"PARAM"];
     [masterVC doSomething:master];
     [master verify];
}

Here is a whole article explaining how exactly to write the OCMock isKindOfClass method (it is not existing by default) and how to use it: http://blog.carbonfive.com/2009/02/17/custom-constraints-for-ocmock/
