Question

Considering this class :

@interface SampleClass : NSObject {
    NSMutableArray *_childs;
}

- (void)addChild:(ChildClass *)child;
- (void)removeChild:(ChildClass *)child;

@end

How can i test when i add a child if the _childs array contains one object without adding a property to access it (because i don’t want allow client code to access the _childs array) ?

Answer 1

Create a @property for it in the class extension and use the property for all accesses, that way you are testing and using the same code.
