The Art of Unit Testing with Examples in JavaScript

The art of unit testing is not limited to learning the right set of tools and practices. The art of creating great tests lies in understanding the essence, finding the right strategy for each specific case, and knowing how to get out of situations where testing turns into a chaotic process. This book offers tips and advice that will completely change your approach to software testing.

You will learn to create readable and easy-to-maintain tests, study testing strategies at the organizational level, diagnose problems, work with legacy code, and perform "uncompromising" refactoring. The book is filled with practical examples and familiar scenarios. The third edition has been supplemented with methods characteristic of object-oriented, functional, and modular programming styles. The examples use JavaScript, TypeScript, and Node.js.
