Integration tests

[kirawi]

I'm wondering if it would be practical to have a set of integration tests, especially to test hotkeys & rendering. Having it available for monkeys like me would make it a lot easier to test if everything is running correctly.

The kakoune approach of integration tests is interesting. But I wonder if we can do something like rust compiler sort of ui tests, like using comments? I think this is in @archseer todo. @kirawi are you interested in doing this?

Unfortunately, I'm not very familiar with creating tests, and I will be too busy :(

[archseer]

For integration tests, we can probably construct an Editor with a single document, wrap it in a ui::Editor then call handle_events to inject keys.

I'll be creating a testing harness for #228

@archseer Do we still need this issue? I no longer feel as strongly about integration tests specifically.

[archseer]

Yes, integration tests are important. Probably even more than the current set of unit tests.
