BDD INTRO




Amir Barylko - TDD Patterns               MavenThought Inc.
WHY TRADITIONAL
                    PROJECTS FAIL?

  • Delivering       late or over budget

  • Delivering       the wrong thing

  • Unstable       in production

  • Costly     to maintain


Amir Barylko - Real World BDD              MavenThought Inc.
BDD PRINCIPLES

  • Behaviour   Driven development is about implementing an
     application by describing its behaviour from the perspective of
     the stakeholder

     • Enough       is Enough

     • Deliver      stakeholder value

     • It’s   all behaviour
