 ### Testing asynchronous requests
-When testing asynchrounous requests your request will be sent on a different thread from the one on which your test is executed. It is important to keep this in mind, and design your test in such a way that is has enough time to finish. For instance  ```tearDown()``` when using ```XCTest``` and ```afterEach()``` when using [Quick](https://github.com/Quick/Quick) and [Nimble](https://github.com/Quick/Nimble) will cause the request never to complete.
