Get some Unit Tests and CI

[ccoffrin]

I could use some help. I have no idea how to test JS.

I use Mocha but there are several other popular unit test systems. What did you have in mind as far as priorities for developing tests?

[ccoffrin]

Nothing too major. In other code bases I try make some easy integration tests that emulate typical student interactions. Then use code coverage reports to make sure I have hit 80-90% of the code.

This is a good example,

I no nothing about JS unit testing frameworks or how to do CI outside the browser, so your experience would be much appreciated!

Sure I can take a stab at it this weekend. Setting up the framework is fairly easy and Mocha is very straightforward.

I am using mocha.js for testing and blanketjs for code coverage. Do you have a preference as to how to include these in the project? Do you want to continue to load external libraries from a CDN or would you prefer to move these libraries into the project using Bower?

[ccoffrin]

In light of modern web tools, I am a web-dev novice; so I'll trust your judgement on this one.

My feeling is that it is best to load the libraries via a CDN. That way, it is one less tool that a would-be contributor would need to learn.

These are not mission critical tools so if the break due to an external library update that is not a huge deal.
