Golden-layout: Meta-Issue: Testing

[martin31821]

At the moment, we have no testing, there were some unit tests, but I think none of them are working right now.

In order to avoid regressions, we should add:

• Unit tests for most of the code, including coverage and coverage reports on PRs
• Maybe E2E tests on a platform like BrowserStack to make sure we won't break backwards compatibility.

I've signed up for the project and it's been accepted as an Open Source account.

Does anyone have a preference for testing frameworks? My default is to work with Cucumber and TS so I'll knock something up to demonstrate it working if that works for everyone.

I'm a fan of mocha / karma, but the interface is nearly identical as far as I can tell, so that shouldn't matter.
If possible, open a WIP PR, so we can take a look in early stages.

Good idea. Will do.
