Hi all,
I have a very simple
newtype Index = Index Int deriving (Eq, Ord, Enum)
for which I have written tests with both HSpec and QuickCheck. Specifically, I have written tests for "==", "/=", "compare" (for all of EQ, LT, and GT), and "toEnum" & "fromEnum". So I thought I had _very_ thoroughly covered that one line. :-)
Unfortunately, after running "stack clean ; stack test --coverage" I see in the HTML report that only Eq has been tested and that Ord and Enum have _no_ coverage (i.e. "never executed").
(The module also has some regular functions and an explicit Show instance [all with tests] and those are apparently fine. So coverage does seem to work but not the way I expect?)
What am I doing wrong?

This sounds like it may be a ghc bug. Can you open a ticket at https://gitlab.haskell.org/ghc/ghc? Cheers, - Ben
