The document discusses the importance of a 'whole team approach' to agile testing and how Behavior-Driven Development (BDD) can enhance collaboration among project stakeholders. It outlines common challenges faced by new agilists and presents BDD as a solution that fosters communication and shared understanding through concrete examples and collaborative requirements. The presentation also covers BDD's process, tools, and benefits, emphasizing its role in improving quality and agility in software development.

Conventional bonding between Developers and Tester
 Lack of Interaction – working in
Silos
 Lack of Customer Collaboration –
Delayed collaboration with customer
 Diversity in Viewpoint – Leads to
arguments over achieving goal.

Importance - Whole TEAM approach to achieve Agile Quality
✓ Meaningful commitment to Quality
✓ Shared vision of product
✓ Respecting the tests

Common Challenges faced by new Agilist
➢ COMMUNICATION :: “TO PRODUCE AND COMMUNICATE RELEVANT INFORMATION
PROMPTLY”
➢ COLLABORATION :: “TO MAKE TESTING, DEVELOPMENT AND BUSINESS COLLABORATE”
➢ HOW TO TEST EARLY BUT NOT DO ANTICIPATORY TEST DESIGN?
➢ FIT QA IN THE SAME ITERATION AS DEVELOPMENT?
➢ IN SPRINT AUTOMATION IN THIS PROJECT
➢ SHOULD I FOCUS ON MANUAL OR AUTOMATION
➢ FEAR TO LOSE IDENTITY
➢ CHANGING REQUIREMENTS /LAST MINUTE CHANGES
➢ NOT ENOUGH INFORMATION ON THE STORY
➢ CONTINUOUS TESTING

Have heard about BDD.

Perception Vs Perspective
How some thing appears is always a matter of Perspective.
Everyone has a unique perspective and all are important

Why BDD?
Behaviour-Driven Development process that
encourages collaboration in a software project
between developers, QA, project managers,
and the business team.
Express a requirement as a Story
BDD story is written by the whole team and
used as both requirements and executable test
cases.

▪ BDD is second generation agile methodology.
▪ BDD is Outside-in(Test First approach), high-automation, agile methodology.
▪ Dan North created a BDD framework at the end of 2003.
✓ Where to start in the process
✓ What to test and what not to test
✓ How much to test in one go
✓ What to call the tests
✓ How to understand why a test fails

It’s often said that BDD is TDD ‘DONE RIGHT with a specific mind-set.

Conversation
BDD believes in……
 Working Together to find better solutions
 Use real world examples to build a shared
understanding of the domain
 People understand requirements best
using concrete examples.
 Examples clear up
ambiguity and misunderstandings.
 Examples expose missing requirements.
 Examples force everyone to think harder
about a problem.

Key features of Behaviour Driven Development
Is it a Tool?
Is it about Testing?
Is it about Silo and
acceptance criteria?
✓ It’s about Communication and Behaviour
✓ It’s about Exploring the Unknown.
✓ It is about sharing and understanding.
✓ It is about telling STORIES through CODE

BDD guided Development
Vision
Goals
Capabilities
Features
Stories
Acceptance Criteria
Examples
Code
What do you want to
achieve?
What will the business get out of it?
What do users and stakeholders
need to deliver these goals?
you can break a feature
up into stories
How can your application
help the users to do this?
Concrete examples are
easier to understand
Acceptance criteria
help clarify features.

20. How BDD Works
Gherkin - Story and
Scenario
BDD Process
Cycle
BDD Language

21. © 2016 Fiserv, Inc. or its affiliates.21
BDD’s -Language
BDD uses Domain Specific Language called Gherkin.
Gherkin is a ubiquitous language for analysis, which is used to write Features,
Scenarios, and Steps. The purpose of Gherkin is to help us write concrete
requirements.
Feature files mean different things to different people:
• They are requirements for product owners.
• They are acceptance criteria for developers.
• They are test cases for testers.
• They are scripts for automators.
• They are descriptions for other stakeholders.
Thus, BDD fosters healthy collaboration because feature files are pertinent to all
stakeholders (or “amigos”). Features files are like receipts – they’re a “proof of purchase” for the
team. They document precisely what will be delivered.

BDD - Story and Scenarios
Story
As a <role/persona>
I want <activity>
So that <business value>
Scenarios
Given <context/precondition>
When <event/action>
Then <outcome/post
condition>

BDD Process Cycle with TDD
“You can’t stay agile without clean code
You can’t have clean code without refactoring
You can’t refactor without good automated tests”

10 reasons why BDD helps better
✓ Communication between business and development is extremely focused as a
result of common language.
✓ Business needs tie directly to the code that is written.
✓ Developers know what test cases they should write to accommodate TDD.
✓ All the underlying benefits of TDD become more easily realized.
✓ Code is easier to maintain.
✓ Code is self documenting.
✓ Stories are easier to “groom” – breakdown, task and plan.
✓ Teams can be more agile.
✓ Developers can be trained / on-boarded easier.
✓ There is more visibility into team progress and status.
