unittest — Unit testing framework — Python 3.11.5 documentation : the example makes reference to a symbol as
await AsyncConnection. But that symbol isn’t defined anywhere in the stdlib - the only other file in the git tree besides the
unittest.rst that mentions it is the What’s New for the 3.8 release, which contains the same example.
Was this intended to be something else? Was it an abstract reference (“fill in the correct routine here”)?
