Behaviour Driven Development is an increasingly popular Agile development practice that turns testing on its head. It turns automated acceptance testing from a verification activity, done once the development work is done, to a specification activity, with tester involvement starting from the word go.
In this talk, we will look at how Behaviour Driven Development radically changes the traditional tester role in Agile projects, and empowers them to contribute much more to the successful outcomes of the project. We will see how collaboratively written acceptance criteria help reduce assumptions and errors in the early phases of the project, and help ensure that the features being built are both well understood and valuable to the business. We will look at ways to write more effective, easier to maintain automated acceptance tests. And we will see how automated and manual acceptance test reporting can be combined to provide valuable progress and release preparation reporting.
