Overview of this book

The MEAN stack is a collection of the most popular modern tools for web development; it comprises MongoDB, Express, AngularJS, and Node.js. Starting with MEAN core frameworks, this project-based guide will explain the key concepts of each framework, how to set them up properly, and how to use popular modules to connect it all together. By following the real-world examples shown in this tutorial, you will scaffold your MEAN application architecture, add an authentication layer, and develop an MVC structure to support your project development. Finally, you will walk through the different tools and frameworks that will help expedite your daily development cycles. Watch how your application development grows by learning from the only guide that is solely orientated towards building a full, end-to-end, real-time application using the MEAN stack!

Testing your Express application

In the Express part of your MEAN application, your business logic is mostly encapsulated inside controllers; however, you also have Mongoose models that obfuscate many tasks, including data manipulation and validations. So, to properly cover your Express application code, you will need to write tests that cover both models and controllers. In order to do so, you will use Mocha as your test framework, the Should.js assertion library for your models, and the SuperTest HTTP assertion library for your controllers. You will also need to create a new test environment configuration file that will provide you with special configuration options for testing purposes, for example, a dedicated MongoDB connection string.
