Behavior-Driven Refactoring: Beyond Arrange-Act-Assert People often ask me if Arrange-Act-Assert (AAA) is the same as Given-When-Then (GWT). On the surface, they look similar. Both give structure to tests. Both help organize thinking. But there’s a fun…

Ever refactor your API and break all your tests? I discovered that starting with Given-When-Then instead of Arrange-Act-Assert gives me freedom to change implementations without touching specs.

AAA locks you to APIs. GWT locks you to behavior.

GWT Everywhere – A Shared Language for Tests and Specs A colleague once told me he’d developed a mixed approach to testing: Given-When-Then (GWT) for some tests, Arrange-Act-Assert (AAA) for others. His rationale made sense at first: developer-oriented…

Every time we switch between English and code, we pay a tax. GWT removes that tax by creating a single language spanning from acceptance criteria to unit tests.

What if your whole team could read every spec without context-switching?

Tests pass. Coverage looks good. But you only find what you thought to test.
AI can trace your user flows through the codebase, map navigation paths, find dead ends, and spot gaps in your e2e tests before a user does.

Stop Testing Your Code: Why the Best Developers Focus on Human Behavior Instead The Developer’s Blind Spot From the ivory tower of our IDEs, it is easy to mistake a clean pull request for a successful product. We spend weeks architecting “perfect” systems, only to be blindside…

What if we stopped testing code and started understanding people instead? Most developers focus on happy/angry paths, but the real business impact often comes from other paths, such as the "forgetful path"—when users get distracted by browser tabs.

BDD Conversations Before Automation I keep hearing the same concern: “We don’t practice BDD because we don’t know how to automate Given/When/Then statements.” This stops teams before they even start. They see BDD as a testing framewo…

Teams skip BDD because they can't automate it. But BDD isn't about automation—it's about clarity through conversation. The Given/When/Then format is a thinking tool. Automation is a separate, strategic decision that comes after.

Event Sourcing and the Past Tense of Given I was thinking about event sourcing and event storming the other day, and something clicked. Events in these systems are always named in past tense: “OrderPlaced,” “PaymentReceived,” “InvoiceAged.”…

Event sourcing and BDD share the same pattern: we can only capture what has happened, not what hasn't.

No more "Given I have not paid"—instead, "Given seven days have passed."

What events has your system captured?
