Behaviour Driven Development (BDD) fosters clear project visibility for all stakeholders by using understandable examples to describe software behavior. It involves defining scenarios like account withdrawals with specific contexts and expected outcomes. This document includes references to resources for further learning about BDD and its implementation with Cucumber.

6. BDD ensures everyone (technical or not) has thorough visibility into
the project’s progress.

11. Story: Account Holder withdraws cash
As an Account Holder
I want to withdraw cash from an ATM
So that I can get money when the bank is closed

12. Scenario 1: Account has sufficient funds
Given the account balance is $100
And the card is valid
And the machine contains enough money
When the Account Holder requests $20
Then the ATM should dispense $20
And the account balance should be $80
And the card should be returned

13. Scenario 2: Account has insufficient funds
Given the account balance is $10
And the card is valid
And the machine contains enough money
When the Account Holder requests $20
Then the ATM should not dispense any money
And the ATM should say there are insufficient
funds
And the account balance should be $20
And the card should be returned
