iphone - Testing asynchronous code on iOS with OCunit

Question

Does anyone know of any existing library that allows testing asynchronous code with OCUnit? I'm thinking about something like GHAsyncTestCase but that delivers from SenTestCase.

I'm asking because if I don't find any I'm going to port GHAsyncTestCase to OCUnit but I don't want to duplicate work done already by someone else.

Piotr:

You might be interested in the work I've done with Mimic, a network stubbing tool written in Ruby which lets you stub requests at a high-level and can be used from your Objective-C using the supplied wrapper.

With regards to asynchronous testing, please take a look at a little utility I wrote called AssertEventually.

This example shows both Mimic and assertEventually in action.

In addition, you might want to look at Kiwi - it's a great little Objective-C testing framework that is built on top of OCUnit. I recently contributed a patch to port my AssertEventually behaviour over to Kiwi which lets you write things like:

id someObject = nil;
[do SomethingThatFetchesSomeObjectAsynchronously];
[[theObject(&someObject) shouldEventually] equal:@"some result"];
