Test.StateMachine

The main module for state machine based testing, it contains combinators that help you build sequential and parallel properties.

Sequential property combinators

forAllCommands

Arguments

:: Testable prop

=> (Show (cmd Symbolic), Show (resp Symbolic), Show (model Symbolic))

=> (Traversable cmd, Foldable resp)

=> StateMachine model cmd m resp

-> Maybe Int

Minimum number of commands.

-> (Commands cmd resp -> prop)

Predicate.

-> Property

existsCommands

:: forall model cmd m resp prop. (Testable prop, Foldable resp)

=> (Show (model Symbolic), Show (cmd Symbolic), Show (resp Symbolic))

=> StateMachine model cmd m resp

-> [model Symbolic -> Gen (cmd Symbolic)]

Generators.

-> (Commands cmd resp -> prop)

Predicate.

-> Property
