- 24. Expected Func&onality: The customer should be able to withdraw money from his account via an ATM machine
- 25. BDD Example: Given the account has balance of INR 5000 When the customer requests INR 1000 Then the account is debited by INR 1000
- 26. BDT Example: Given the account is in credit And the dispenser contains cash When the customer requests cash Then ensure the account is debited And ensure cash is dispensed And ensure the card is returned
- 27. New Expected Func&onality: The customer should be able to withdraw money from his account only if his card is valid
- 28. BDT Example -‐ updated: Given the account is in credit And the card is valid And the dispenser contains cash When the customer requests cash Then ensure the account is debited And ensure cash is dispensed And ensure the card is returned
