Node.js 8 the Right Way

Behavior-Driven Development with Mocha and Chai

It’s a maxim of programming that testing is good for code health. One strategy for approaching testing is BDD, which advocates articulating your expected behaviors in tests even before you start writing the implementation.

Not all programming problems are equally well suited to the BDD approach, but data processing is one area where it makes a lot of sense. Since the inputs and outputs of the program are quite well defined, you can specify the desired behavior to a high degree even before implementing the functionality.

So in this chapter, let’s take the opportunity to use BDD while parsing the RDF content. Along with Mocha, last seen back in ​Developing Unit Tests with Mocha​, we’ll ...
