Kiwi Helper Class Question

README.md

Background

Warning: I do not know objective-c that well

I'm working in some specs. Sometimes I see an opportunity to use some test helpers to eliminate some duplication in my testing. I'd like to be able to create a helper class that is able to wrap some of these helper verification methods and re-use it to clean up some of my specs.

Problem

I don't have access to any of the should flavor of Kiwi verifications within my tester. I'm assuming because I'm not within the SPEC_BEGIN / SPEC_END (as those macros call other Kiwi methods).

The Question

What do I need to do in order to create a helper class to be able to utilize the should macros in Kiwi?

SomeClassSpec.m

#import "Kiwi.h"

@interface SomeHelper : NSObject
-(void) shouldHave:(int)expectedCount OfSomethingOn:(SomeClass)someObject;
@end

SPEC_BEGIN(SomeClassSpec)

describe(@"SomeClass", ^{
  __block SomeHelper* tester;
  __block SomeClass* theClass;
  
  beforeEach(^{
    theClass
    tester = [[SomeHelper alloc] init];
  });
  
  it(@"can utilize the helper", ^{
    /** ... some setup ... **/
    [tester shouldHave:7 OfSomethingOn:theClass];
  });
});

SPEC_END

@implementation SomeHelper
-(void) shouldHave:(int)expectedCount OfSomethingOn:(SomeClass)someObject
{
  /** ERROR: should is not avialable **/
  [[theValue([someObject theCount]) should] equal:theValue(expectedCount)];
}
@end
