Lesson 9: Testing MEAN Applications

In previous Lessons, you learned to build your real-time MEAN application. You went through Express and AngularJS basics and learned to connect all the parts together. However, when your application becomes bigger and more complex, you'll soon find out that it's very difficult to manually verify your code. You will then need to start testing your application automatically. Fortunately, testing a web application, which was once a complicated task, has become much easier with the help of new tools and suitable testing frameworks. In this Lesson, you'll learn to cover your MEAN application code using modern test frameworks and popular tools. We'll cover the following topics:
