Add tests to the repo

[suve]

Looking at .gitignore, there's this line:

/testcases/*

which hints that some tests have been written for the program, but are excluded from the repository.

It would be useful to have these tests as part of the repo.

1. It would make contributing easier, as it'd provide a way to check against regressions.
2. It would allow third-party redistributors (e.g. Linux distro packagers) to verify that the program runs as intended.

eagle eye! 😉

But I did not write any test automation. I will put them into an own branch for now and we will see whether it helps or whether someone wants to use them for something more useful. 😁

I took a brief look at the testcases branch. The setup is a bit similar to something I've done before, so here's my suggestion:

• put each test into it's own separate directory
• use the same name for the "input" and "expected output" file in each test

It is then trivial to write a Makefile that treats each directory name as a target name, so when you run make some-test it runs the program as needed and compares output. I can take care of this part, if you'd like.

The problem I see, is, that the html can change but the result still be valid. But I guess you can easily adjust the testcases if need. 🤷

So, I myself will not find the spare time for this. If you want to contribute this, feel free! 😃

I'd suggest making the tests run on an intermediate representation consisting of the characters and the state of each. This would help test the part more likely to break (the parser) and avoid changes that only affect the state to html conversion. Additionally a separate set of tests could be added for testing state to html translation
