ELI5 — The Vibe Check

BDD is like writing your tests in plain English so your non-coder boss can also understand them. Instead of code, you write 'Given the user is logged in, When they click logout, Then they should see the login page'. Everyone gets it!

Real Talk

Behavior-Driven Development extends TDD by writing test specifications in a human-readable format using Given/When/Then syntax. Tests describe system behavior from the user's perspective and serve as both documentation and executable specifications.

Show Me The Code

Feature: User Logout
  Scenario: Logged in user logs out
    Given the user is logged in
    When they click the logout button
    Then they should be redirected to /login
    And they should see 'You have been logged out'

When You'll Hear This

"We write BDD specs with the product team so everyone agrees on behavior." / "BDD bridges the gap between devs and non-technical stakeholders."

Test Case

A test case is one specific scenario you want to check. 'Does the login work with a correct password?' — that's a test case.
