We're a group of 4 developers on a ajax/mysql/php web application. 2 of us end up focusing most of our efforts on testing the application, as it is time-consuming, instead of actually coding. When I say testing, I mean opening screens and testing links, making sure nothing is broken and the data is correct.
I understand there are test frameworks out there which can automate this kind of testing for you, but I am not familiar with any of them (neither is anyone on the team), or the fancy jargon (is it test-driven? behavior-driven? acceptance testing?)
So, we're looking to slowly incorporate automated testing. We're all programmers, so it doesn't have to be super-simple. But we don't want something that will take a week to learn... And it has to match our php/ajax platform...
The Question: Which testing framework will allow us to jump in right away without spending a lot of time learning the syntax and/or a new programming language.
