This is a workshop to build product while practicing impact mapping, feature writing, specification by examples and applying test first approach. Workshop will cover all practices that will help in translating product vision to product increment. Facilitator will demonstrate how to convert specifications in code by using BDD tools.​​ Facilitator will help in crafting product vision, coming up with product features and introducing how to write examples for features. Session will demonstrate how to convert specification into product increment, living documents and build test automation. Learning objectives: • What is Impact Mapping and how to use it for product discovery? • How to create product features using Impact Mapping? • How to write examples for features while practicing specification by examples? • How to translate examples into test using BDD before writing code? • Importance of living code • Best practices for BDD

Example
Build it Right
Build the Right Things

25. What are Specifications by Example
 Thin Slices of System Behavior
 That Deliver Business Value
 Described as concrete examples
 That are potentially automatable
 To create executable specifications
 Captured in live documentation

26. Specifications By Collaboration

27. What are Specifications by Example

Gherkin
Given “Naveen” enter source “Office” and destination “Airport”
and time “5.30pm” with 2 seats available
And he provides his mail id “naveenhome@gmail.com” and
phone number “9810547500”
When Click on “Submit”
Then Display message “Ride Share” with “OK” button
And take “Naveen” to “home” page on click on “OK”
And his ride should be shown on top

28. Acceptance Criteria
• Feature: Quick Post
Successful submission will redirect user on home page
Given “Naveen” enter source “Office” and destination “Airport”
and time “5.30pm” with 2 seats available
And he provides his mail id “naveenhome@gmail.com” and
phone number “9810547500”
When Click on “Submit”
Then Display message “Ride Share” with “OK” button
And take “Naveen” to “home” page on click on “OK”
And his ride should be shown on top

29. Gherkin
 Feature – Name of feature
 Scenario – Behavior to be developed
 Given – Pre-conditions
 When – Actions to be performed
 Then – Expected Result
 And – Use for multiple Given, When & Then
 But – Describe exception cases
 Scenario Outline – Define multiple scenarios
 Examples – Multiple Scenarios
 Background – Avoid repeated Given

30. Can We start Sprint Now?
 Why not? We have testable specification so let’s start
 Let’s make a rule for team to have examples for every
specification
 If examples not available then specification will not get picked up
for sprint
 Convert examples in test is our first activity
 Write enough code to pass those tests

31. Test First
Test

Test Again
Refactor

32. Behavior Driven Development
BDD
Given Scenario
Then Expected
Outcome
When Perform
Action

33. Let’s get started
 Write Feature to describe scenario in Gherkin
 Eclipse, Java, Cucumber, Selenium, Junit
 Create Test Runner class file
 Generate Steps file
 Write code to pass test

34. BDD - Characteristics
 A testable story (it should be the smallest unit that fits in an
iteration)
 The title should describe an activity
 The narrative should include a role, a feature, and a benefit
 The scenario title should say what's different
 The scenario should be described in terms of Givens, Events, and
Outcomes
 The givens should define all of, and no more than, the required
context
 The event should describe the feature
