synopsis:           Library for lockstep-style testing with 'quickcheck-dynamic'
description:        Lockstep-style testing is a particular approach for blackbox
                    testing of stateful APIs: we generate a random sequence of
                    APIs calls, then execute them both against the system under
                    test and against a model, and compare responses up to some
                    notion of observability.
tested-with:        GHC ==8.10 || ==9.0 || ==9.2 || ==9.4 || ==9.6 || ==9.8
