$ sudo npm install –g avoid using sudo, follow the instructions in from this resource on how to install Node.js correctly. If you encounter the lack-of-permissions issue when you run the previous command, run this: $ npm install –g Note We use a specific version (the latest as of this writing is 1.16.2) to prevent inconsistency in this book’s examples caused by potential breaking changes in future versions of Mocha. Mocha is a mature and powerful testing framework for Node.js. The source code for this post is in the ch3 folder of the practicalnode GitHub repository ( ). Project: writing the first BDD test for Blog.To get you started with the Node.js testing framework, Mocha, in this post, we cover the following:
Similar to building apps themselves, most of the time software engineers should use a testing framework. It differs from TDD in language, which encourages collaboration between product owners and programmers. The behavior-driven development (BDD) concept is based on TDD. At the same time, rich user interface (UI) / user experience (UX) can be tested with headless browsers such as PhantomJS. But, certain parts such as standalone services and REST API can be and should be tested thoroughly by the TDD. Historically, web apps have been hard to autotest, and developers relied heavily on manual testing. Test-driven development (TDD), as many of you might know, is one of the main, agile development techniques. The genius of TDD lies in increased quality of code, faster development resulting from greater programmer confidence, and improved bug detection (duh!).
