I just started developing an app that connects to this URL and retrieves the rate exchange for a given pair of currencies.
I need to test the HTTP request and I ended up learning about Kiwi and Nocilla. However, I'm completely new to any kind of testing and there's not a lot of information about Nocilla that can help me to get started.
I added all the NSURLConnectionDataDelegate
and NSURLConnectionDelegate
methods to the ViewController
of my single view application, and the data retrieved from the URL is stored in @property (strong, nonatomic) NSMutableData *receivedData;
. When I run the program everything works as expected but I haven't been able to pass the test I wrote:
SPEC_BEGIN(URLConnectionSpec)
__block URLConnectionAppDelegate *app_delegate;
__block URLConnectionViewController *view_controller;
describe(@"URLConnection", ^{
beforeAll(^{
[[LSNocilla sharedInstance] start];
app_delegate = [[UIApplication sharedApplication] delegate];
[[app_delegate shouldNot] beNil];
view_controller = app_delegate.viewController;
});
afterAll(^{
[[LSNocilla sharedInstance] stop];
});
afterEach(^{
[[LSNocilla sharedInstance] clearStubs];
});
context(@"When testing", ^{
it(@"should do something", ^{
stubRequest(@"GET", @"http://rate-exchange.appspot.com/currency?from=USD&to=EUR&q=1");
[view_controller beginCommunication];
[[expectFutureValue([NSString stringWithUTF8String:[view_controller.receivedData bytes]]) shouldEventuallyBeforeTimingOutAfter(2)] equal:@"{\"to\": \"EUR\", \"rate\": 0.76610740799999999, \"from\": \"USD\", \"v\": 0.76610740799999999}"];
});
});
});
SPEC_END
I'm sorry for the long snippet of code.
The test always failed with this message
URLConnection_WhenTesting_ShouldDoSomething] : 'URLConnection, When testing, should do something' [FAILED], expected subject to equal "{"to": "EUR", "rate": 0.76610740799999999, "from": "USD", "v": 0.76610740799999999}", got ""
I tried changing the time to even 10 seconds hoping that the test finished too early but I got the same results. I don't know why 'receivedData' is empty.
I would really appreciate any help
