Learn the principles behind test-driven development (TDD) and behavior-driven development (BDD) and see how Jasmine, RSpec and Cucumber can be used to your advantage. This book examines some of the leading technologies used for testing.

You'll see how to use Jasmine’s features to work with a JavaScript application. You will learn how to use Mini Test and RSpec with Ruby and Rubymine. Finally, you’ll use Cucumber to develop your software using a BDD approach.

Understanding test automation is a vital skill for any web developer. Practical Test Automation breaks down for you some of the important TDD and BDD technologies on the modern web.

What You'll Learn

• Test an example JavaScript application with Jasmine
• Use Jasmine with JS Bin
• Work with Minitest for test-driven development
• Test an example Ruby project with RSpec
• Use Cucumber and Gherkin for behavior-driven development
• Integrate Cucumber with RSpec
