Documentation
testableType :: RandomGen g => Type -> Maybe [Gen g Bool BV Integer] Source #
Given a (function) type, compute generators for the function's arguments. Currently we do not support polymorphic functions. In principle, we could apply these to random types, and test the results.
randomValue :: (BitWord b w i, RandomGen g) => Type -> Maybe (Gen g b w i) Source #
A generator for values of the given type. This fails if we are given a type that lacks a suitable random value generator.
randomInteger :: (BitWord b w i, RandomGen g) => Gen g b w i Source #
Generate a random integer value. The size parameter is assumed to vary between 1 and 100, and we use it to generate smaller numbers first.
randomWord :: (BitWord b w i, RandomGen g) => Integer -> Gen g b w i Source #
Generate a random word of the given length (i.e., a value of type [w]
)
The size parameter is assumed to vary between 1 and 100, and we use
it to generate smaller numbers first.
randomStream :: RandomGen g => Gen g b w i -> Gen g b w i Source #
Generate a random infinite stream value.
