doctest-prop-0.2: Allow QuickCheck-style property testing within doctest.

Safe HaskellNone



This package allows you to write QuickCheck properties and HUnit assertions within doctest, using functions that keep silence when test succeeds and print out the test outputs otherwise.

To enjoy behavior driven development in Haskell, first import Test.DocTest.Prop, and use prop, propWith and unit to write in-place tests, as follows.

>>> import Test.DocTest.Prop
>>> prop $ \x -> x*2 == x+x
>>> prop ((<2) . fromEnum :: Bool -> Bool)
>>> propWith (quietArgs{maxSize=3}) $ (<10).length
>>> assert $ 1+1==2



prop :: Testable p => p -> IO ()Source

Test the QuickCheck property.

propWith :: Testable p => Args -> p -> IO ()Source

prop with customized arguments.

quietArgs :: ArgsSource

The standard arguments for QuickCheck but the chatty flag is off.
