BDD is a new, exciting approach to developing software that has been shown to reduce rework and increase customer satisfaction. While other testing tools focus primarily on “are we building the thing right?”, BDD tools attack the problem of software directly at its source: “are we building the right thing?” By retaining all the benefits of automated unit testing, while extending them upstream to cover requirements, we cut the Gordian knot of risk and complexity to unleash hyper-productivity.
Why is BDD so effective?
•As a form of Test driven design, BDD helps produce frugal, effective and testable software.
•As a development tool, BDD frameworks like SpecFlow provide many convenience functions and are pre-integrated with powerful libraries like Nunit and selenium to make writing tests a snap.
•As a collaboration tool, BDD helps ensure the “three amigos” (tester, analyst and developer) sync up – ahead of time.
•As a facilitation technique, BDD enables product owners to efficiently provide the team with concrete examples that clarify the true intent of a user story and define the boundaries.
•As a reporting tool, BDD captures functional coverage, mapping features to their acceptance criteria to their test results, in an attractive hierarchical presentation.
Want functional documentation? How about documentation that is guaranteed to be correct, because every feature maps to its test results? Witness the holy grail of traceability – executable specifications.
We will start with a brief “show and tell” with several examples of reports generated from BDD tools, to provide context and to immediately highlight the bottom line business value that makes an investment in BDD so worthwhile.
We will spend a few minutes talking about the pre-requisites, so attendees have an idea of what type of investment they are signing their teams up for. We will see that in return for a modest amount of investment in tools and training, very significant benefits can be realized, and the benefits compound over time.
This workshop then dives right in to Gherkin, the structured English language technique used to capture BDD specifications. We will spend the better part of the session learning the tricks and techniques that make for robust and maintainable gherkin specifications. We will review and critique lots of examples, both good and bad.
Finally, we will spend a few minutes reviewing how to organize BDD tests for best results while generating reports, and to ensure that they stay neat and tidy even as you build more and more of them over time.
