Test-Driving JavaScript Applications

Chapter 5Test-Drive Node.js Apps

In part 1, we covered various techniques for writing automated tests, verifying the behavior of asynchronous functions, and tackling dependencies. We’re now ready to put them all together as we test-drive the design and implementation of an entire Node.js application, from start to finish.
