Now we don't have any ;-(. It's a hobby project, but still it should have something.

Hi @tatianajiselle!

Thanks for being interested in this project. I'll prepare an empty test case template later and it's gonna be a placeholder for the future unit tests. I'll post an update in this issue, when it's ready.

Cheers
