Testing An Angular CLI Project in a Headless Environment

I recently started a new project and we used [Angular CLI][4] to get started. Angular CLI, as in the name, is a command line utility for creating and managing Angular 2 projects. Using Angular CLI to create a project is very easy and it gives you a great starting point for new Angular 2 projects. The only draw back I found was that in my mind it wasn't CI ready.

Angular CLI out of the box gives you a few unit tests and an end to end (e2e) test. This is great because you can generate a project and set up your build server to build the artefacts. This is where I ran into problems.

Having everything generated for you is great until something you want to do does not work; and this is where I was. I wanted to build and test my angular application on a headless build agent. The generated code from Angular CLI runs tests using Google Chrome by default. Which is fine, but running Google Chrome on a bui

Introduction to Angular

Angular (aka Angular 2) is a new framework completely rewritten from the ground up, replacing the famous AngularJS framework (aka Angular 1.x).

More that just a framework, Angular should now be considered as a whole platform which comes with a complete set of tools, like its own CLI, debug utilities or performance tools.
