Arquillian Graphene 2: JavaScript Unit Testing Examples

I have been doing work with Arquillian for a while. If you need to do integration and unit testing on your JSF application. This is definitely the path to take. It makes testing so much easier to accomplish.

Recently, I have been trying to use Arquillian Graphene 2 to do JavaScript unit testing. I spent a lot of time trying to get the examples on the Graphene 2 - JavaScript Interface wiki to work. I discovered that they were slightly incorrect and the source of my grief. One of the great things about an Open Source world is that I updated the wiki with the correct information.

I have created a couple of Proof of Concept (POC) projects to demonstrate how to use Graphene to do JS testing. The first example uses Graphene in stand-alone mode. This mode allows you to test your JavaScript outside of a container, but using a browser implementation like: PhantomJS, Chrome, Firefox, or Safari.

The Apache Maven NetBeans 8.0 project can be downloaded from Bitbucket here: graphene-js-poc

You will need to execute this from the command line, or use the JS Unit Test custom goal in NetBeans.

The next project is simply a combination of the code from the Arquillian Graphene 2 wiki combined into a more complex project. This project is designed to run in a container. In my case, Glassfish is the container of choice. The slickness of this approach becomes quite apparent when you see the application server start-up, execute the tests, and shutdown gracefully.

The Apache Maven NetBeans 8.0 project can be downloaded from Bitbucket here: graphene-poc.

The project includes a JSF example along with testing JavaScript.

If you need to do unit testing of your JavaScript, this may be an option to consider. Please make sure you read the wiki and understand the limitations of the approach however. You can use my code as an example to help guide you along the path.
