Usage

@interface MochaAsyncTest : NSObject
+ (void)runBlock:(void (^)(MochaAsyncDone done, MochaAsyncDoneWithError error)) runTestBlock;

+ (void)runBlock:(void (^)(MochaAsyncDone, MochaAsyncDoneWithError)) runTestBlock timeout:(NSTimeInterval) timeout;
@end

You can use it for async test.

[MochaAsyncTest runBlock:^(MochaAsyncDone done, MochaAsyncDoneWithError error) {
    /*
     async function
    */
    done();
    // or
    error(error);
}];

done

When pass the test, you have to call done()

fail

When fail the test, you have to call fail(NSError *error)

describe(@"MochaAsyncTest", ^{
    it(@"pass test", ^{
        [MochaAsyncTest runBlock:^(MochaAsyncDone done, MochaAsyncDoneWithError error) {
            // async function
            double delayInSeconds = 2.0;
            dispatch_time_t popTime = dispatch_time(DISPATCH_TIME_NOW, (int64_t)(delayInSeconds * NSEC_PER_SEC));
            dispatch_queue_t queue = dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0);
            dispatch_after(popTime, queue, ^(void) {
                done();// => done async test
            });
        }];
    });
    it(@"fail test", ^{
        [MochaAsyncTest runBlock:^(MochaAsyncDone done, MochaAsyncDoneWithError error) {
            // async function
            double delayInSeconds = 2.0;
            dispatch_time_t popTime = dispatch_time(DISPATCH_TIME_NOW, (int64_t)(delayInSeconds * NSEC_PER_SEC));
            dispatch_queue_t queue = dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0);
            dispatch_after(popTime, queue, ^(void) {
                // fail
                fail([[NSError alloc] initWithDomain:@"xxx" code:0 userInfo:@{}]);
            });
        }];
    });

});

Known problem

When use error(NSError *error) with Kiwi, fail test, but throw exception...
