JavaScript Test Automation Frameworks

Web development has changed dramatically over the last three decades. At the advent of the Web, nearly all applications consisted of static content rendered in one or two browsers. Since that time, the Web has evolved into a colossal collection of dynamic web pages and applications rendered in half-a-dozen or more browsers on behalf of billions of users.

In addition to dramatic changes in web applications, JavaScript test frameworks have also morphed to keep pace with this everevolving ecosystem. In this Refcard, we will delve into the conceptual underpinnings of modern JavaScript test automation frameworks and explore six of the most popular frameworks available today. Along this journey, we will compare the different design and architecture decisions of each framework and how well these various trade-offs are suited for different requirements and contexts.
