How to effectively test the project

[theandrew168]

I've been thinking about how I could verify that DerzForth "works" and that new changes didn't break anything. I think there are a couple of routes:

1. Find a simulator that works and abstract out the IO-specific portions
2. Test on a real Longan Nano / Wio Lite and use something like pexpect to test commands / responses

Either way, having something in place to verify behavior will definitely pay itself off as new features / optimizations are introduced.
