The document is a presentation by Aditya Chourasiya on Cucumber, focusing on Behavior Driven Development (BDD), Test Driven Development (TDD), and Acceptance Test Driven Development (ATDD). It covers definitions, hands-on examples, and the installation process of necessary tools, including Ruby and Cucumber, aimed at quality assurance professionals. The presentation encourages discussion and emphasizes the structure of feature and step definition files for effective testing.

Test : 1+1=2

![What is Acceptance Test Driven Development
[ATDD]Acceptance tests are a part of an overall testing strategy. They
are the customer tests that demonstrate the business intent of a
system. Component tests are technical acceptance tests
developed by an architect that specify the behavior of large

- 10. Gherkin Ruby community has many great tool for testing, one of early test framework was RSpec. However due to limitations it was evolved as cucumber. In real life gherkin is a variety of cucumber but in current context Gherkin is the language that Cucumber understands. Tags: Feature, Scenario, Scenario outline Steps: Given-When-Then, And , But, Or Hook: Before, After , Around Feature: LogIn Action Test Description: This feature will test a LogIn and LogOut functionality Scenario: Unsuccessful Login with InValid Credentials Given User is on Home Page When User Navigate to LogIn Page And User enters UserName and Password But The user credentials are wrong Then Message displayed Wrong UserName & Password

Prerequisites for hands-on Cmd admin mode and type choco install ruby choco install ruby2.devkit choco install chromedriver choco install ansicon Start command prompt with ruby and type Gem install watir Gem install rspec Gem install cucumber Gem install colorize References: http://www.guru99.com/cucumber-installation.html
- 13. Files in Cucumber Remember to create 2 Files – Features and Step Definition Features file contain high level description of the test scenario in simple language Steps Definition file contains the actual code to execute the test scenario in the Features file. Your structure looks like: --/features test.feature ---/step_definitions test.rb To run this feature type in command line: cucumber test.feature -r step_definitions Example of Features Feature: search aditya chourasiya on google Scenario : Visit google.com and search aditya Given: I am on google.com When: I type aditya And: I click search Then: I should see my linkedin in result page Example of Step Definition Step 1: Given (/^ I am on google.com$/) do Browser.goto "http://google.com" -To go to google Browser.click "" -To go to google end

Editor's Notes
- #8: Benefits: By focusing on the test cases first, functionality used by clients is clear to team. Used in conjunction with a version control system, when tests fail unexpectedly, reverting the code to the last version that passed all tests However does not perform sufficient functional tests
- #9: It is a collaborative practice where users, testers, and developers define automated acceptance criteria. ATDD helps to ensure that all project members understand precisely what needs to be done and implemented. Failing tests provide quick feedback that the requirements are not being met. The tests are specified in business domain terms.
- #10: BDD focuses on the behaviors of your system exhibits than the implementation details of it.
- #11: .feature files can be considered a method invocation. Before Cucumber can execute a step it must be told, via a step definition, how that step should be performed.
