Testing

[DanielVoogsgerd]

Currently, Brane has painfully low test coverage. This introduces quite a bit of risk when working on establish parts of Brane.

We should really find some sort of testing strategy for Brane so that we can be confident that the alterations we are making are correct.

As a stopgap measure, I suggest we start implementing Cargo insta in some crates so that we at least know when stuff changes

Testing parts that interface with the machine would require some nasty mocking right now so that is not even the focus in my opinion, but for crates like brane-dsl there is no reason not to test I think

To Do:

• Implement snapshot regression testing Snapshot regression testing #245

@Lut99 What do you think?
