Add more Tests

[senden9]

Hi!

I think, now that we have automatic CI test runs, a few more test would be helpful. For that i suggest to let the emulator panic or return an error if we hit an unknown command. At the moment unknown commands are simply ignored.

It is maybe a good idea to test against the 6502_functional_test.a65. What say the other people?

Aye, that's a great idea!
Maybe there's a way to auto-generate some tests from the resource (and others) that you mentioned. Do you want to tackle that one?

Also a good + funny idea. But I have not much spare time under the week. So will not claim that now.

We got quite a few more unit tests now, so I'll go ahead and close this.
The functional test is still untouched but I don't think we should keep that issue open any longer. Probably there are better ways to do it by now than my crude attempt in #17.
