YALA-FEAT As a developer, I'd like Unit & Integration testing

sigh

Yes, I know. I really should have done unit and integration testing while I was developing the site, but as this startup started as a side project, I really didn't think anything would come of it. I mainly used this as a way to learn the Remix technology.

But now that this is starting to look like a viable product, this really does need unit testing and integration testing.

All I ask is that you use React Testing Library, not Enzyme.
