Test-Driving JavaScript Applications (Pragmatic Bookshelf)
Test-Driving JavaScript Applications (Pragmatic Bookshelf)
Wednesday, 04 January 2017

The subtitle of this book is Rapid, Confident, Maintainable Code, and author Dr. Venkat Subramaniam shows that whether you use Node.js, Express, MongoDB, jQuery, AngularJS, or directly manipulate the DOM, you can test-drive JavaScript, repaying your investment in writing tests with code that's predictable and cost-effective to change.

<ASIN:1680501747>

The author shows how to write meaningful, deterministic automated tests with Karma, Mocha, and Chai. You're shown how to test asynchronous JavaScript, how to deal with dependencies, measure code coverage, and create lightweight modular designs of both server-side and client-side code.
