Cucumber Essential Training

Course details

Cucumber is a tool for behavior-driven development (BDD), which allows you to write assertions in plain language that are then testable by code. By making written requirements actually testable, Cucumber provides a common language for business and engineering professionals. In this course, learn how to use Cucumber to implement agile practices like BDD, test-driven development (TDD), and acceptance test-driven development (ATDD). Instructor Shashi Shekhar goes over the basics of BDD, TDD, and ATDD, and then dives into the essentials of the Cucumber workflow. Along the way, gather tips on how to map user stories to features, add hooks, generate reports, and apply techniques to make BDD maintainable.

Learning objectives
Integrate Cucumber into your test-driven development.
