Testing with DalekJS

So far we learned how to test our JavaScript code. After that, we found out how to write user interface tests with Phantom.js. All these are really helpful, but it will be even better if we are able to run a real browser and control it. With DalekJS, this is possible. It's a really nice Node.js module that comes with a command-line interface tool and submodules for major browsers such as Google Chrome, Firefox, and Internet Explorer.

Let's see how everything works and install the command-line tool of DalekJS using the following command:

npm install -g dalek-cli
