@tiangolo Added no coverage on some tests as my typo changes might have triggered the codecov check on files that had not been checked in a while.

Great catch. also jfyk last commit is duplicate of #2038.

Awesome! 🔍 🕵️

These 2 no cover are not necessary as Codecov takes the coverage from the tests running in all Python versions.

The only disadvantage is that running locally in a single Python version coverage will never be at 100% for that file, but 🤷
