The Art of Unit Testing, Third Edition  updates an international bestseller to reflect modern development tools and practices. This expanded edition teaches you to write unit tests for async and observable code, as well as methods of faking functions, modules and refactorings. You'll explore test patterns and organization, working with legacy code, and even "untestable" code. The many tool-agnostic examples are presented in JavaScript, and are carefully designed so that they apply to code written in any language. about the technology

Unit testing is a universally-adopted practice on dev teams of all sizes. Great developers will tell you that testing is as much a state of mind as a collection of tools and practices.   The Art of Unit Testing, Third Edition  takes you below the surface and understand how unit testing can transform the way you deliver and maintain software. Now with examples in JavaScript, this new edition has been updated to reflect the characteristics of a modern codebase, including async and modularized, distributed services. The practices and patterns you'll learn can also be easily applied to other languages, including C#, Java, and Python. about the book

The Art of Unit Testing, Third Edition  guides you step by step from your first simple unit tests to building complete test sets that are maintainable, readable, and trustworthy. Now with examples using JavaScript and Node, this expanded third edition teaches you to write unit tests for async and observable code, as well as methods of faking functions, modules and refactorings. You'll get to grips with complex subjects such as mocks and stubs, explore how to handle tricky legacy codebases, and save yourself time with tests that function for both frontend and backend applications.   The Art of Unit Testing, Third Edition  is an essential guide for any unit tester who wants to feel confident writing code that's easier to create, maintain, and adapt.
