Asynchronous Testing

It's very common for iOS applications to have components that collaborate with the main thread via background threads. Towards this end, Kiwi supports asynchronous testing, thus enabling integration tests - testing multiple objects collaborating together - as well as unit tests (testing a single component in isolation using mocks).

An example, using LRResty library:

This will block until the matcher is satisfied or it times out (default: 1s)

    context(@"Fetching service data", ^{
        it(@"should receive data within one second", ^{

            [[LRResty client] get:@"http://www.example.com" withBlock:^(LRRestyResponse* r) {
                NSLog(@"That's it! %@", [r asString]);
                fetchedData = [r asString];
            }];

            [[expectFutureValue(fetchedData) shouldEventually] beNonNil];


        });

    });

Setting the acceptable timeout:

This blocks for two seconds instead of the default one second.

[[expectFutureValue(fetchedData) shouldEventuallyBeforeTimingOutAfter(2.0)] equal:@"expected response data"];
