"serving up 80 separate assets is insane." in production it certainly is, we minify, concatenate and use a CDN. In dev if you concatenate and do not use source maps you compromise your debugging experience.

The "refresh all browsers" is only refreshing browsers pointed at my local dev Discourse instance, youtube is safe. I run a multiple monitor setup, I press a key and see right away the effect of my change.

We use fixtures and fabricators, we test individual classes, we mock and all that jazz. I am totally open to PRs that simplify and streamline our test suite, the point though is that now I am never blocked on my test suite in dev despite a full run taking 3 minutes.
