Expected Func&onality:

The customer should be able to withdraw money from his account via an ATM machine

Given the account has balance of INR 5000 When the customer requests INR 1000 Then the account is debited by INR 1000

BDD 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

BDT Example:

New Expected Func&onality:

The customer should be able to withdraw money from his account only if his card is valid

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

BDT Example -‐ updated:

Test specifica*on styles

Story: Animal Submission As a Zoologist I want to add a new animal to the site So that I can share my animal knowledge with the community

Impera*ve Scenario

Reference: hCp://wa*rmelon.com/2010/12/10/cucumber-‐impera*ve-‐or-‐declara*ve-‐that-‐is-‐the-‐ques*on/

Given I am on the animal crea*on page When I fill in Name with ‘Alligator’ And fill in Genus with ‘Alligator’ And check Lay Eggs And click the Create buCon Then I should see the no*ce ‘Thank you for your animal submission!’ And the page should include the animal’s name, genus and lay’s eggs

Declara*ve Scenario

Reference: hCp://wa*rmelon.com/2010/12/10/cucumber-‐impera*ve-‐or-‐declara*ve-‐that-‐is-‐the-‐ques*on/

Given I am on the animal crea*on page When I add a new animal Then I animal should be created successfully

What does this do for me?

How did we accomplish this?

Who is doing the ac*on?

What is the business func*onality?

Ac*ons and verifica*ons happen implicitly Depicts a user flow

Given auc&oneer creates a sale And 5 items are added to the sale When auc&oneer starts the sale And auc&oneer sets a star*ng bid of 5000 And buyer_1 bids And buyer_2 bids Then auc&oneer Sells the item And buyer_2 wins the item
