ATDD And BDD The Great Beat Down…or…Debate

Bob Galen & Mary Thorn

Velocity Partners & Ipreo

It seems as if the agile methods have lots of DD’s going on. There is:

  • TDD – Test Driven-Development
  • ATDD – Acceptance Test Driven-Development
  • BDD – Behavior Driven-Development

TDD is focused more on unit tests and for the purposes of this talk (debate, steel cage death match, discussion) we’ll not focus on it. Instead we’ll explore ATDD and BDD usage from within agile teams.

In this webinar, Bob attacks it from the perspective of the user stories, acceptance criteria, and conversation. A bit of an old-fashioned twist, but that’s Bob…old.

Mary attacks it from the perspective of acceptance tests, Gherkin, having Product Owners write tests, and Cucumber automation; clearly a more up-to-date focus.

The goal was to explore what “Good” ATDD and BDD “looks like” in agile contexts, and hopefully, for Mary and Bob to “meet in the middle” and for both to “survive”.

Key Takeaways

  1. A solid overview of the intent behind the User Story as a requirement artefact.
  2. A solid overview of Acceptance Test Driven Development, including Behaviour-Driven Development.
  3. An understanding of the intent behind Acceptance Criteria.
  4. An understanding of the balance required in the User Story and the Acceptance Criteria/tests.
