lake test

Stream: batteries

[Kim Morrison]

batteries#787 is an attempt to start moving us away from make test, to the happy new world of lake test.

For now this requires building some infrastructure locally, that I hope will eventually be taken over by lake itself.

(I would be happy if people outside the usual batteries crowd also looked at this, including e.g. @Mac Malone, as hopefully we can learn from this to work out how to do testing better across all repositories.)

Part of the motivation for this is the new lean-action Github CI action that @Austin Letson has been working on: for that to work well, we're going to need to have a "standard entry point" for testing.

I think this is great! Should we just run both testing frameworks for a bit to work the kinks?

[Mac Malone]

The test code looks good to me!
