Systems Analyst: What is the difference between TDD and BDD?

TDD — test-driven development. BDD — behavior-driven development.

TDD:

• Focus on code correctness.
• Developer-focused.
• xUnit frameworks.

BDD:

• Write behavior specs first.
• Focus on user behavior.
• Stakeholder-focused.
• Cucumber, SpecFlow.

Key differences:

• TDD — tests.
• BDD — behavior.
• TDD — developer.
• BDD — stakeholder.
• TDD — xUnit.
• BDD — Gherkin.
