Mockito has problems mocking arrays about ocmockito HOT 13 CLOSED

I've reproduced this problem using the instructions from @lightforce.

Also found another problem that I believe is related. The same error occurs when using dictionaries as arguments in messages to mock object.

@interface Actor : NSObject
- (void)doIt:(NSDictionary *) dict;
@end

@implementation Actor
- (void)doIt:(NSDictionary *) dict {}
@end

@interface SomeTest : SenTestCase
@end

@implementation SomeTest

- (void)testBigTrouble
{
    NSDictionary *dict = [NSDictionary dictionaryWithObjectsAndKeys:
                          @"value1", @"key1", @"value2", @"key2", nil];
    [mock([Actor class]) doIt:dict];
}

@end

This results in an error message like

error: -[SomeTest testBigTrouble] : -[__NSArrayM setObject:atIndexedSubscript:]: unrecognized selector sent to instance 0xa2449b0

On that note, almost all of the examples in the README are broken. So... this seems to be a high priority bug.

Thank you @codyaray for pointing that out. As for my example it crashes inside MKTInvocationMatcher at line 51, where the new array subscription syntax is used. I think a solution might be to use Clang's _has feature. E.g.

#if __has_feature(objc_array_literals)
    // new way.
    _argumentMatchers[argumentIndex] = matcher;
#else
    // old way (equivalent).        
    [_argumentMatchers replaceObjectAtIndex:argumentIndex withObject:matcher];
#endif

Thanks, you guys. I'll check it out.

Any updates?

I can't reproduce either problem. But @lightforce you have a clear symptom. What kind of OS / Xcode version are you using that doesn't support new literals?

from ocmockito.

I'm using OCMockito 0.23 downloaded from http://qualitycoding.org/resources/ with XCode 4.3.2 on Mac OS X 10.7.5 and building for iPhone 5.1 Simulator. (Thanks for the TDD tutorial that references OCMockito!) Is there any other information that could help?

from ocmockito.

@codyarray It's odd, but I still can't reproduce. I'm using your Actor / SomeTest sample above, in a Cocoa Touch Static Library project. Could you boil it down to a sample project that you could email to me?

from ocmockito.

Absolutely. I just sent an email with a sample project. Thanks for your help!

I configured my testing unit to use OCMockito via Cocoapods

pod 'OCMockito', '~> 0.23'

The Apple LLVM compiler 4.2 is used and the deployment target is iOS 6.1 for both the test bundle and the Pods project. No test host is set for the testing bundle (logic tests). Although I am able to use the new literal syntax inside the test classes without problems, the literals syntax used inside OCMockito makes the tests crash.

Okay, so I just upgraded to XCode 4.6 (4H127) through the mac app store and the sample I sent no longer fails. Tested with iPhone 5.1 and 6.1 simulators. Hmm.

Though I can't reproduce the problem, I changed the new array use in MKTInvocationMatcher at line 51. @lightforce maybe you could give it a whirl.

Works perfectly. Thx!
