Just for information, for the sake of consistency you could also have used the commodity method `responseWithJSONObject:statusCode:headers:` here instead (defined in `OHHTTPStubsResponse+JSON.h`) which does the `NSJSONSerialization` and adds the `Content-Type` header for you:

```
NSDictionary *expectedResponseDict = @{@"Success" : @"Yes"};
[OHHTTPStubs stubRequestsPassingTest:^BOOL(NSURLRequest *request) {
    return YES;
} withStubResponse:^OHHTTPStubsResponse *(NSURLRequest *request) {
    return [[OHHTTPStubsResponse responseWithJSONObject:expectedResponseDict statusCode:200 headers:nil]
            requestTime:kRequestTime responseTime:kResponseTime];
}];
```

It doesn't change anything but is more readable IMHO. I don't know if you were aware of that commodity method ;)
