Behaviour Driven Development

I’m writing a book! But it isn’t finished yet. In the meantime, here’s a sample of the kind of information that we’re likely to include in it. Please let me know if there’s anything else you’d like to see explained.

Please also see this related page on Embracing Uncertainty, as it’s highly relevant to the way in which I approach BDD!

Starting the Journey

These links provide an overview of BDD and its history, from Dan North’s initial inception to the use of scenario-based frameworks that predominates today. While reading these, spot the places where we mention conversation, questioning and feedback. These are at the heart of BDD. The language we use – examples, scenarios, Given, When, Then – is also relevant.

Converting from ATDD / TDD

Want to know how to move from a TDD or ATDD mindset to a BDD one? These links focus on the differences between the methodologies. If you’re already doing TDD or ATDD very well, you may find some hints for sharpening your practices here.

Feature Injection: From Vision to Scenario

Chris Matts, an analyst involved in the initial BDD inception, takes some of the patterns in BDD into the analysis space. These practices can really help in phrasing scenarios effectively and focusing on business-valuable differentiators.

Capabilities and Complexity Estimation

When we write our scenarios, we think about the capabilities we’re delivering, rather than the features and UI that we’re using to drive out those capabilities. Sometimes when we’re talking about something new, it’s hard to decide what the outcome of a scenario should be. If we’re talking about things which are well-understood, people become bored and it wastes time. These articles outline ways in which the certainty of capabilities can be identified, and the different approaches and ways of using BDD within those different domains. We also look at approaches for continuous capabilities (aka non-functionals).

Fun

Sometimes we like to play and experiment with the concepts of BDD. I thought these popular nuggets were worth including.
