No problem. If you're not familiar with testing, I'd encourage you to look at unit testing tutorials for the language you work with.

For JavaScript, I love jest. For Python, pytest is great. They both support coverage reports, though I'm not sure if jest generates one as HTML or only in the CLI.

There's plenty of tutorials on YouTube, probably some on here too.
