Cucumber School (Ruby)

Learn BDD with the Cucumber core team

by

Cucumber is a tool for running automated tests written in plain language. Because they’re written in plain language, anyone can read them. Because anyone can read them, they have magic powers that improve communication, collaboration, and trust on your team. The magic is called Behaviour-Driven Development (BDD).

Cucumber School is created and taught by the Cucumber core team. The 10-episode series is based on a proven syllabus taught to hundreds of people in their popular in-house training classes. Through three hours of practical video content, coding exercises, and thought-provoking questions, you’ll learn the individual skills needed to excel with Cucumber and BDD.

Software developers and business people often misunderstand each other. Those misunderstandings cost our industry billions. Once you learn you’ve built the wrong thing, you have to make an uncomfortable choice: stay late to meet the deadline, hack in a low-quality solution, or just ship it anyway.

It doesn’t have to be this way.

Behaviour-Driven Development (BDD) is an approach to software development that bridges the communication gap between the business, developers, and testers and gets everyone speaking the same language. You’ll discover how BDD and Cucumber, the world’s most popular BDD tool, help teams communicate requirements with more precision, discover defects early, and produce software that stays maintainable over time.

You’ll learn how to install and run Cucumber, and how to write executable specifications and living documentation using the Gherkin plain text format. In between the coding you will also learn powerful collaboration and analysis techniques such as Discovery Workshops and Example Mapping. Through a worked example, you’ll use Cucumber to guide the development of a simple social network, using techniques such as Modelling by Example and Hexagonal Architecture to create a codebase that is easy to maintain and test. You’ll learn how to use Cucumber with Selenium and how to strike a good balance between Acceptance Tests and Unit Tests.
