It has been very easy to integrate with other services I have using it, such as Google Apps Scripts. The price makes sense when you think about how much time could save by not having to write all of your own tests or writing them from scratch yourself. Nothing so far that would lead me away from recommending this product. There are some things that can be improved (and have already been), but nothing serious enough to keep people off of it completely. If you need help testing your code against APIs, then this should definitely be considered. This tool removes one of the most tedious parts of my job - building out test cases.
