stub method with block of code as parameter with OCMock

block, ios, ocmock, stub

Solution

Yes. The easiest way would be to accept anything:

id mockGeocoder = [OCMockObject mockForClass:[CLGeocoder class]];
[[mockGeocoder stub] reverseGeocodeLocation:[OCMOCK_ANY] completionHandler:[OCMOCK_ANY]];

It gets a bit trickier if you want to verify a particular block is passed in. One option is to make your completion handler a property of your class, initialize it when you initialize your class, and have the test match it directly:

// in your class
@property(copy)CLGeocodeCompletionHandler completionHandler;

// in your class's init method
self.completionHandler = ^(NSArray *placemark, NSError *error) {
    //
}

// using the completion handler
[geocoder reverseGeocodeLocation:location completionHandler:self.completionHandler];

// the test
id mockGeocoder = [OCMockObject mockForClass:[CLGeocoder class]];
[[mockGeocoder stub] reverseGeocodeLocation:[OCMOCK_ANY] completionHandler:yourClass.completionHandler];

Problem

Is there a way to stub method, that takes block as it's parameter? For example mehod: ``` - (void)reverseGeocodeLocation:(CLLocation *)location completionHandler:(CLGeocodeCompletionHandler)completionHandler; ```
