The document discusses Cucumber, a tool that supports Behavior Driven Development. It begins with an introduction to BDD and how it differs from traditional test-driven development by focusing on describing behavior from the perspective of stakeholders. The document then provides an example of how Cucumber allows writing tests and scenarios in a natural language format like Gherkin. It also outlines how Cucumber can integrate with different programming languages and platforms. Finally, it discusses some additional tools that can be used with Cucumber for capabilities like parallel test execution and publishing features as documentation.

4. But don’t we already do this??

5. What we really do….
As a Retail Customer, I want to withdraw money
from my Account so that I can get Money.
Unit Tests
Should_Not_Dispense_When_the_ClientAccount_has_money_le
ssthan_minimum_amount()
Should_withdraw_Money_When_appropriate_Sum_Found()
Should_Not_Withdaw_Post_Expiry_Date()
Should_Withdraw_Post_Expiry_Date()
Should_Be_A_Valid_User()
Should_Not_Withdraw_When_Negative_Balance()
Should_Be_A_Valid_Account_Type()
Should_Return_Error_When_ATM_Is_Without_Cash()

6. Restricted view on Behaviour

7. Difference in thinking
CLIENT
CUSTOMER
BUYER
SHOPPER
PUNTER
DEV QA BA CLIENT PO

8. Increased Ambiguity  LOST

9. BDD – Outside In
VISION
GOAL
FEATURE
STORY
SCENARIO
CODE

10. Scenarios and Examples in Ubiquitous Language
HAVING CONVERSATION IS
MORE IMPORTANT
TALKING THROUGH
EXAMPLES HELP DISCOVER
CONSIDERS MULTIPLE
STAKEHOLDERS

11. BDD Vs TDD
• Development Methodology Vs Development
Technique
• Business Driven Vs Design Approach
• Customer Writing Tests Vs Developers writing
Tests
• Focus on Behavioural Aspect Vs
Implementation Aspect

12. Cucumber Example…
Story:
As a user
I want to login with my details
So that I can get access to the site
Scenario: User uses wrong password
Given a username 'jdoe'
And a password 'letmein'
When the user logs in with username and password
Then the login form should be shown again
