Test-Driven Development for React/Redux in an Isomorphic Application

Online Courses


In Test- Driven Development for React/Redux in an Isomorphic Application LiveLessons, Hany Elemary, Lead Consultant at ThoughtWorks, explains a paradigm shift in the testability of front-end code made possible with React/Redux. The video introduces isomorphic applications and their unique benefits and challenges, and then jumps straight into the architecture of React/Redux applications from a testability perspective. Hany follows test-driven development (TDD) principles while building a real-world example--a search application--to demonstrate effective end-to-end testing. Popular testing tools for React/Redux applications, including Enzyme, SinonJS, Expect, Nock and Mountebank, are highlighted.


The need for building highly performant and maintainable user interfaces is now greater than ever. React, a library designed and developed by Facebook, can solve many of the existing problems users face today--including poor browser performance while handling dynamic interactions with high loads of data. React also solves a lot of challenges for front-end developers. Due to its popularity, other supporting frameworks, such as Redux, came into the picture to make applications more predictable, testable, and easier to debug. However, they come with a different approach to front-end development and testing.

Testability is key to maintaining the quality of any application while building confidence in the code as developers refactor their work. Writing proper tests can be a lengthy process, especially for newer frameworks such as React/Redux. Test-Driven Development for React/Redux in an Isomorphic Application LiveLessons quickly gets you up-to-speed on when to build isomorphic applications, how to effectively test your React and Redux code, and how to confidently refactor code while ensuring that business functionality is maintained.
