Cucumber is a behavior driven development tool that serves as documentation, automated tests, and development aid. It is written in a ubiquitous language that is understood by all team members, including business stakeholders. Cucumber features are written as scenarios in plain English using a language called Gherkin. These scenarios can then be automated as tests in various programming languages and integrated into continuous integration pipelines. Cucumber provides a way for teams to collaborate and ensure the behavior of an application is developed and functioning as intended across its lifecycle.

5. But don’t we already do this??

6. What we really do….
As a professional, I want to search for a conference
in India so that I can upgrade my skillset.
? User Stories are High Level
? Where to start with TDD?
? What to Test and what not to
Test
? What to call the tests?
? How much to test in one go?

7. Restricted view on Behaviour

8. Difference in thinking
SITE
LOCATION
PLACE
AREA
LOCALITY
DEV QA BA CLIENT PO

9. Increased Ambiguity  LOST

10. BDD – Outside In Pull Based
VISION
GOAL
FEATURE
STORY
SCENARIO
CODE

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

12. 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

13. 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
