SpecFlow, Gherkin and some things

I’ve picked up using them

Marcus Hammarberg

Specification by example is not about the tools

!

it’s about communication

Whether we choose to call it BDD or ATDD or Specification by Example, we want the same

result – a shared common understanding of what is to be built

to try to build the ‘thing’ right the first time. !

We know it never will be, but the less rework, the better.

!Janet Gregory

Hence: Let’s talk tools!
