Example text

Finally, we did a deep dive into the ng-repeat to see what it is and how we could use it in a variety of situations. As we mentioned earlier, AngularJS has a huge focus on unit testing. To this end, each and every part of AngularJS is easy to unit test. In the next chapter, we will see how we might write some simple unit tests for the controllers we have written so far. We will cover how unit testing is done in AngularJS, how to set up Karma (which is used to run unit tests in AngularJS), and how we can instantiate controllers and set our expectations on their behavior.

It makes it easy to set up tests and then gets out of the way, letting us developers get instant feedback on our code and tests. These are the steps to install Karma (as of this writing): 1. Install NodeJS. You can get the installers from here. 2. Install Karma CLI, which allows you to run Karma in an easier step. This is an npm (Node Package Manager) package, so you can install it with the following command: sudo npm install -g karma-cli Introduction to Karma | 37 Windows users can also run this from the command line after NodeJS has been installed successfully.

The function then houses all the controller-specific code. We also introduce a new directive, ng-controller. This is used to tell AngularJS to go instantiate an instance of the controller with the given name, and attach it to the DOM element. log() statement. Dependency Injection Syntax and AngularJS The notation that we have used is one of the two ways in which we can declare AngularJS controllers (or services, directives, or filters). The style we have used (and will use for the remainder of the book), which is also the recommended way, is safe-style of Dependency In‐ jection, or declaration.
