Running tests

First make sure that all dependencies are installed:

$ cabal install --only-dependencies --enable-tests

cabal

Just run

$ cabal test

and return code will indicate success or failure. However, you won't get nice test output.

runhaskell

If you want nice output you can use runhaskell:

$ runhaskell -isrc -itest test/Spec.hs

Alternatively, you can build and run the test suite manually:

$ cabal configure --enable-tests --disable-optimization && cabal build && ./dist/build/spec/spec

ghci

The fastest way to run your specs is with ghci. Make sure that .ghci is only writeable by you:

$ chmod go-w .ghci

Then you can run the specs with:

$ ghci test/Spec.hs
*Main> :main

After modifying code use:

*Main> :reload
*Main> :main

(note that the :reload will be much faster than loading the code initially, this makes a big difference for larger projects)
