<div><br></div></pre><div>This gives the advantages that a) clearly indicate what http scenario we are testing and b) remove params that don't make sense for the particular scenario under testing e.g. that is we simulate a status of (404) but we need to pass all params eg. data, interval, timeout, etc. But this doesn't limit us, we can do that if we want and use the full blown method with all the params attached.</div>
<div><br></div><div>I have created two branches in my fork, one that uses a blocks approach inside the testing class [2] and one that the functionality is extracted in a helper class that the testing classes can use [3]. The second approach was created because there was common code and didn't want to duplicate it over the testing classes. </div>
