Some articles seem slightly embarrassing to me after I see them published. I thought this might be one, but I think the point should be well-taken: we’re way too invested in dogmatic process trappings. This blog post for Ranorex tells the story of a day in a life where we don’t talk about a process, we just live it, with the singular goal of delivering high-quality software frequently.
Breaking Through the Barriers to BDD (14-Jun-2018)
I think I’m getting a better feel for the interview-style webinar, not having done much of them in the past (this is my… um… second one). This webinar is a discussion around things like organizational resistance to BDD, and touches on the core notions for what can make BDD succeed in your organization.
The ABCs of Acceptance Test Design (7-Jun-2018)
In this blog post for Ranorex, I present seven design principles for the tests you’ll craft as part of practicing behavior-driven development (BDD) or acceptance test-driven development (ATDD). Stick to these principles and you’ll create a body of tests that returns many benefits while allowing you to keep your sanity.
Simon Knight interviewed me for the Gurock webinar “BDD Testing Skills,” delivered on April 13.
During this session we talked about:
Succeeding With Test-Driven Development at a Distributed Start-up (17-Jan-2018)
In this blog post for Gurock’s blog, I talk about my experiences doing test-driven development (TDD) at a small startup: Where did we succeed, where did we fail, and what would I change?
Clarifying Scope with Scenarios in Behavior-Driven Development? (19-Jan-2018)
In this article written for Gurock’s blog, I talk about the values of negotiating around scenarios when doing behavior-driven development (BDD). Rather than delve deep into the narratives (given-when-thens), this focus will help when it comes to negotiating the scope of a given story.
Should We Automate All of Our Feature Scenarios? (8-Feb-2018)
This post for Ranorex’s blog talks about how behavior-driven development (BDD) can help us come to consensus. I share a story about a customer who found value in BDD, even though we were unable to automate their “specs by example.”
Your business doesn’t want to hear about how you “delivered stories.”
The business wants you to deliver value, in the form of what they most likely refer to as features.
A story should trigger a conversation around a feature request. Your software product doesn’t contain stories, it contains features that help users accomplish goals.
Wikipedia describes a user story as “one or more sentences” that capture a user’s needs. Those sentences represent a brief description or summary based on the planning and preparation so far, and they are reminders of the conversation that you must continue to have around the feature you will build. The sentences are not the feature. They aren’t even the full story, in most cases, as it often takes the requester several more oral sentences or even paragraphs to say what they really want.
If you think about stories as a simplified form of a requirements document (“a couple sentences”), you’re constraining agile to be a small tweak to how you did things before, with a trendier name. That diminishes the most important aspect of how agile can help you deliver software successfully: Through continual collaboration and oral communication. Without understanding of the importance of collaboration, stories end up being another waterfall-like hand-off document.
On another front: Too many teams waste time over the wording of a story. It’s a discussion point, not an artifact. The “standard” story template should help you clarify feature requests by asking you to think about who needs them and why. But otherwise spending time on precise word-smithing of a story writeup misses the point. You’re going to discuss it, and you can iron out any ambiguities as you do.
Stories provide only minimal value as an artifact. The ensuing discussion is where the details come out. Unfortunately, most of us can’t fully recall details from a conversation a half year prior, or even a half month prior. Granted, the details end up embodied in the software, but source code more often than not does a poor job of expressing such details concisely and simply. Even programmers must sometimes spend hours to determine just what the code does for the smallest of features.
We need a better artifact than the few sentences that represent a story. Many successful teams have found that the best way to capture system behaviors is in the form of acceptance tests, best derived by use of acceptance test-driven development (ATDD) or BDD. The acceptance tests supplant the nebulous conversation with real meat. A test’s name describes the goal it accomplishes, and its narrative provides an example that quickly relates the details of system behavior. The set of test names describes the complete set of designed system behaviors. The tests capture the important detail behind the discussion triggered by the story.
A story is not a feature, and it should always trigger a conversation.
