Introduction

Surikae replace a method by blocks.
It’s helpful for unit testing for Objective-C.

Installation

Import Surikae folder to you project.

How to use

Use +surikaeWithSelector:surikae:context of NSObject.
It replace the selector of the Class by surikae block.
If you want to replace an instance method, use -surikaeWithSelector:surikae:context of NSObject. This effect is available in the context block only.

See StopWatchTest.m

[NSDate surikaeWithSelector:@selector(date)
    surikae:^()
    {
        return [NSDate dateWithYear:2012 month:2 day:17 hour:0 minute:0 second:second];
    }
    context:^()
    {
        [self.stopWatch start];
        second = 1;
        [self.stopWatch stop];
        ASSERT_EQUAL_DOUBLE(1.0, self.stopWatch.time);
    }
];

If you need these effect more long period, use +registedSurikaeWithSelector:surikae of NSObject.
In this case IUTSurikae class retains UITSurikae object.
When you retrieve all replaced methods, call +[NSObject removeAllSurikaes].

See StopWatchTest2.m

- (void)setUp
{
    [super setUp];
    second = 0;
    [NSDate registedSurikaeWithSelector:@selector(date)
        surikae:^()
        {
            return [NSDate dateWithYear:2012 month:2 day:17 hour:hour minute:minute second:second];
        }
    ];
    self.stopWatch = [StopWatch new];
}

- (void)tearDown
{
    self.stopWatch = nil;
    [NSDate removeAllSurikaes];
    [super tearDown];
}
