Find Solid JavaScript Testing

[ethanimooney]

Need to find a good way to test the JavaScript files.

Initial thoughts were to use Jest, but considering that this uses Node and not Maven, it may not be a good long-term option.

Another finding was Jasmine, but this seems to be either much more complex than needed or not quite what is needed.

shaquilleh@ also found a way to test JS without a framework, this seems promising but needs more investigation.

Final decision was to use Jest as the testing framework. I currently have it installed on a local branch and will create a pull request when I have created at least the initial few tests

This will stay open as this PR never got approved, but tests are effectively done
