This is a testsuite for Haddock that uses the concept of "golden files". That
is, it compares output files against a set of reference files.
To add a new test:
1. Create a module in the `html-test/src` directory.
2. Run `cabal test`. You should now have `html-test/out/<modulename>.html`.
The test passes since there is no reference file to compare with.
3. To make a reference file from the output file, run
html-test/accept.lhs <modulename>
Tips and tricks:
To "accept" all output files (copy them to reference files), run
runhaskell accept.lhs
You can run all tests despite failing tests, like so
cabal test --test-option=all
You can pass extra options to haddock like so
cabal test --test-options='all --title="All Tests"'
