What is BDD?

BDD is like giving your favorite toy a special instruction manual so everyone can play with it the same way.

Imagine you and your friend are playing with a robot that moves forward, backward, left, and right. You both want to make sure the robot does what you tell it to do, but sometimes you say “go left” and the robot goes right. That’s confusing!

BDD, or Behavior-Driven Development, is a way for people who build things (like robots) to talk about how they should work, using simple language that everyone understands.

Think of it like writing a list of what your toy robot should do:

• When I press up, the robot goes forward.
• When I press left, the robot turns left.

Then, the person building the robot reads that list and makes sure everything works as you said. It’s like making a shared language between you and the builder so everyone is on the same page, no more going in circles!

BDD helps people work together better by focusing on what should happen, not just how it happens.
