Add tests

[dubadub]

As of now we don't have any tests, any contribution would be welcome.

There's a newsletter issue explaining how it works.

I want to work on this issue also can you elaborate more on the details of the issue for me to get a better understanding

[dubadub]

Great, welcome @Atheke! You can just take any file and add unit tests for functions defined in that file at the bottom. See for example in cooklang-import. Given that you have rust installed, you can run cargo test to run them.
