Add BDD test framework

What are you building with SQLPage ?

A small point of sales proof of concept.

What is your problem ? A description of the problem, not the solution you are proposing.

I want to test my web-app frequently.

Describe the solution you'd like

I would like to describe the behavior of the website in Gherkin syntax (Given ..., When ..., Then ...). For webapps based on databases that mostly consist of workflows through forms that is quite a natural way to test. The Ruby community was quite bold on Behavior Driven Development as well.

Describe alternatives you've considered

Test vectors sequences could also be a viable approach to test UI interaction sequences
