GHUnit access private variable

Question

I'm trying to access a private class variable in my unit test:

Class
 - private variable abc;

unit test
category/extension above the unittest m file content
 @property (...) variable abc;

but within the test, I always get a unrecognized selector error... Is there any trick making private variables visible/testable?

Sorry, found nothing using google ;)

Greetings, matthias

Answer 1

try [obj valueForKey:@"_ivar"]

you can also make a category to that class and you can access any private variables during the method

@implementation MyClass (UnitTestAddition)

- (id)getPrivateVariable {
    return _ivar;
}

@end
