Use Cabal. You should read at least the start of section 2 of the Cabal User's Guide.
You should use cabal-install
DOCS: For libraries, use Haddock

You can use QuickCheck or SmallCheck to test pure code. These libraries work best when you have known invariants in your code's behavior. See this Cabal file for an example of how to include tests in your Cabal package.

To get started, try Introduction to QuickCheck. For a slightly more advanced introduction, Simple Unit Testing in Haskell is a blog article about creating a testing framework for QuickCheck using some Template Haskell. For HUnit, see HUnit 1.0 User's Guide

doctest is another testing method similar to python Doctest
