Behavior-Driven Development (BDD)

An approach to designing and verifying systems by writing tests first as clear, natural-language scenarios that describe expected behavior.

Key Points

  • Defines system behavior using readable scenarios (e.g., Given-When-Then) that stakeholders can understand.
  • Follows a test-first workflow where executable specifications drive design and coding.
  • Creates a shared language that bridges product, QA, and engineering.
  • Produces living documentation integrated into version control and continuous integration.

Example

A team building a payment feature writes scenarios before coding: "Given a valid card, when the user submits payment, then the order is marked paid and a receipt is emailed." They automate these scenarios and only write application code until the scenario passes, capturing business expectations as executable tests.

PMP Example Question

Which practice helps align business and technical teams by expressing expected system behavior as English-like, test-first scenarios that guide development?

  1. Behavior-Driven Development (BDD)
  2. Test-Driven Development (TDD)
  3. User Story Mapping
  4. Code Review

Correct Answer: A — Behavior-Driven Development (BDD)

Explanation: BDD uses natural-language scenarios (e.g., Given-When-Then) as executable specifications written before code to drive design and validate behavior.

AI Systems with Claude, for Scrum Masters and Project Managers

Most AI pilots in project management do not fail on the model. They fail because somebody pointed the thing at a decision instead of at a task. This course is built around that distinction, and around the work that follows once you get it right.

Eight teaching sections, taught against one running project from the first lecture to the last. You watch a system get built, then you build the same one against your own sprint. Nothing here is a demo that works only on the example.

You finish with five working systems and you keep them. The sprint report machine turns your board export and standup notes into the report you currently write by hand. The retro intelligence system tells you what the team keeps saying, not just what it said this time. The stakeholder comms engine drafts the update in the register the audience expects. The backlog health monitor flags the quiet decay nobody has time to check for. The risk and dependency tracker follows the chains that actually bite.

Seventy-six working files ship with it, across four sections, so every system is built against real sprint data rather than material invented for a slide. Four sprints of retrospectives, board exports, standup notes, backlog and risk data.
