This is a little output test suit for Haddock. To add a test: 1 Create a module in the "tests" directory 2 Run runtests.hs You should now have output/<modulename>.html but the test will always pass since there is no reference output to compare with 3 To add reference output, do runhaskell copy.hs <modulename> Tips: You can do runhaskell copy.hs to copy all output into reference files You can do runhaskell runtests.hs all to continue despite a failing test
