Tests

[hawkins]

I'd like to write some tests, primarily around the arguments interop and the watch function in general

[hawkins]

Testing this honestly seems like a pain, maybe it just my level of rust (in)experience talking, but having to work with a mocked filesystem, Exec, watcher......

I suppose it's feasible if we broke functions up into parts that leverage library code and parts that decided arguments to give to library code, and only tested the latter?

[hawkins]

Yeah, just to get something out of this, I would skip testing actual filesystem events themselves, and instead test the ability to respond to simulated events and prove that we can reliably:

• invoke commands
• match specific files / globs
• behave correctly with respect to arguments
