Browser Tests (aka Feature Tests, aka Laravel Dusk Tests)

[tabacitu]

@pxpm I thought we'd see if it makes sense to put together browser tests, using Laravel Dusk, which uses Selenium WebDriver under the hood. I've set up a few tests to check how it works, so far so good.

I haven't done this in a while so I'm not sure:

• if dusk tests support Javascript; a lot of the stuff we need to test depend on Javascript;
• if dusk tests can also get run by travis-ci;
• if Laravel TestTools still works, and if so, whether it can help us generate most browser tests, so we don't have to manually write them;

I'll get back to this soon - hopefully it's a possible solution. Having browser tests would GREATLY improve our confidence in not pushing breaking changes.
