Take your testing of JavaScript applications to a new level of efficiency and reliability with the help of this book. Starting with the fundamentals of Jasmine and behavior-driven development (BDD), you will learn about tooling and automation. You will learn how to create a sustainable code base with the help of Jasmine. You will also take a look at integrated testing with React.js and Karma, and how you can speed this process up by faking AJAX requests. As you progress through the book, you will learn about the challenges of testing an application built on top of a framework and how you can prevent your application from suffering from dependency management. You will understand the concept of client-side and server-side rendering and test applications using React.js. You will also learn to automate using webpack and work with JavaScript module systems using ECMA Script 6 (ES6) modules.

By the end of this book, you will be a competent web developer with good knowledge and a strong understanding of how to efficiently use the Jasmine framework for testing purposes.
