QuickCheck-safe reimplements the quickCheck functionality with a pure interface and a very small trusted base (see Test.QuickCheck.Safe.Trusted).

  • uses the existing Arbitrary instances

  • implemented features: testing, result minimization (i.e., shrinking)

  • missing features: expected failures, label frequencies, coverage

The package is targeted at users who want to leverage SafeHaskell for sandboxing.
