Re: [Haskell-cafe] The State of Testing?

If you're writing a library, you need to compile the library with `-fhpc`, i.e. put it in the library stanza, not the testsuite stanza, and then you can compile the test program using your library - the resulting 'tix' file will contain the library coverage reports. You can link a HPC-built library into an executable not compiled with HPC just fine. Normally I only compile the library under HPC mode, link it in a test, and distribute the results from that. That way your coverage reports don't include the test module (which may or may not be relevant.) I normally add a cabal flag called 'hpc' which optionally enables coverage reports for my library, e.g. flag hpc default: False library ... ... if flag(hpc) ghc-options: -fhpc Then when you want coverage reports, just say 'cabal install -fhpc --enable-tests' and the resulting properties executable will spit out the results when run.

Thanks for the advice, all. I've got test-framework, quickcheck, and cabal's test-suite all working together nicely.

Cabal seems to support using hpc to check test coverage. If I add -fhpc to the ghc-options under the test-suite, I get output like "Test coverage report written to dist/hpc/html/tests/hpc_index.html" and "Package coverage report written to dist/hpc/html/test-0.0.0/hpc_index.html", but those html files are just empty tables. How does this work?

I've followed what Johan Tibbell did in the hashable package:

If I had known how much confusion my childhood friends would unleash on the Internet when they, at age 7, gave me a nickname that's spelled slightly differently from my last name, I would have asked them to pick another one. ;)

lol, sorry, I actually double-checked the number of l's before writing that but didn't consider the b's. For future reference I've produced a handy chart:

Letter | Real-name count | Nickname count -------+-----------------+--------------- b      | 1               | 2 l      | 2               | 0 -------+-----------------+--------------- SUM    | 3               | 2

Excellent. I will tattoo it on my forehead.

There is, of course, a simpler (but not necessarily easier :p) solution: change your name to match your nickname!
