find files and exclude some files and a directory

I want to find in a directory all files with extension .hs but exclude all files in a sub-directory sub and some other files with names containing test. I read and experimented with the use of find and prune but did not understand the complex logic and none of my attempts worked.

The naive 

find . -name "*.hs" -not -name '*sub*' -not -name "*test*"

nor 

find . -name "*.hs" -not -path '/sub' -not -name "*test*"

does work. I assume there should be a simple solution to this (relatively) simple issue.

A solution that seems to work is

find . -name "*.hs"   -not -name "*test*"   | grep -v  "sub"

which is simpler than using prune, but can certainly be improved?

Your first attempt excludes all files whose name includes sub.

Your second attempt excludes all files whose path is exactly /sub.

Combine the two to match all files whose path includes sub:

-not -path "*sub*"

However, -prune is the better solution because it skips the directory rather than fruitlessly matching every single entry in it.
