Add tests

[SimenB]

We should have a bunch of tests. There is https://github.com/vadimdemedes/ink-testing-library, but vadimdemedes/ink-testing-library#3 is an issue. We might wanna do some integration tests spawning up Jest and running tests, similar to how https://github.com/jest-community/jest-runner-eslint does it

I would be interested. This would be first time I'd be contributing to OSS though. DO you suppose this would be a good beginner friendly issue ?

Hey @rchandu, thanks for reaching out! I haven't been able to spend the time to bootstrap any tests here, so in its current state it's not very beginner friendly, unfortunately... Thanks for offering though, I'll ping you whenever I get back to this project 👍
