Web Development with MongoDB and Node - Third Edition

Overview of this book

Node.js builds fast, scalable network applications while MongoDB is the perfect fit as a high-performance, open source NoSQL database solution. The combination of these two technologies offers high performance and scalability and helps in building fast, scalable network applications. Together they provide the power for manage any form of data as well as speed of delivery. This book will help you to get these two technologies working together to build web applications quickly and easily, with effortless deployment to the cloud. You will also learn about angular 4, which consumes pure JSON APOIs from a hapi server. The book begins by setting up your development environment, running you through the steps necessary to get the main application server up-and-running. Then you will see how to use Node.js to connect to a MongoDB database and perform data manipulations. From here on, the book will take you through integration with third-party tools to interact with web apps. You will see how to use controllers and view models to generate reusable code that will reduce development time. Toward the end, the book supplies tests to properly execute your code and take your skills to the next level with the most popular frameworks for developing web applications. By the end of the book, you will have a running web application developed with MongoDB, Node.js, and some of the most powerful and popular frameworks.

Preface

Chapter 9. Testing Your Code

Up until this point, we've been pretty much flying by the seat of our pants when it comes to the code we've been writing. We literally had no way of knowing whether the code worked until we tested it out in an actual browser.

In this chapter, we will cover the following topics:

  • Running tests with the Mocha test framework
  • Writing tests with the Chai.js assertion library
  • Spies and stubs with Sinon and Proxyquire
  • Writing your first test
  • Testing your application

Tests are great for ensuring that your code functions properly, but they're also awesome for preventing new, unexpected bugs from suddenly popping up because of an innocent little change you made to some unsuspecting code.
