The libraries in this subsection are as follows:
- QuickCheck: Property-checking with automatic test-case generation
- doctest: Writing tests and expected results directly in haddock comments
- HSpec, HUnit, tasty: Traditional unit-testing libraries
- criterion: Benchmarking time usage
- weigh: Benchmark allocation
There are two testing libraries that are rather novel in Haskell: QuickCheck and doctest. QuickCheck lets the programmer just state a property for a function, leaving it to the library to try proving it false.
Doctest builds on the ingenious idea of combining test cases with docstrings. It's especially useful in libraries, because it gives users reading the documentation always up-to-date information about properties and use ...
