Behavior Driven Development with AngularJS & Jasmine
7 likes2,287 views
This document discusses Behavior-Driven Development (BDD) and how it can improve software development. BDD is a methodology that uses examples in natural language to define desired software behaviors and tests those examples throughout development. It aims to bridge communication gaps between developers, testers, and business stakeholders. The document outlines BDD processes and how they differ from traditional waterfall and test-driven development. It also provides an example template for writing BDD scenarios in Gherkin, a domain-specific language.
