[Haskell-beginners] hpc doctest

[ryan]

Hello,

Are there any known issues with doctest and hpc? 

Cabal test runs correctly, but hpc doesn't seem to see anything.  I have
tried to make some of the test fail on purpose so see it hpc would pick
it up, since there is additional output from cabal test when there is a
failure, but it doesn't help.
