Module STM_sequential.MakeSource

Parameters

module Spec : STM.Spec

Signature

Sourceval cmds_ok : Spec.state -> Spec.cmd list -> bool

A precondition checker (stops early, thanks to short-circuit Boolean evaluation). Accepts the initial state and the command sequence as parameters. cmds_ok catches and ignores exceptions arising from next_state.

A generator of Spec.cmd sequences. Accepts the initial state as a parameter. arb_cmds catches and ignores generation-time exceptions arising from Spec.next_state.

Sourceval agree_prop : Spec.cmd list -> bool

The agreement property: the command sequence cs yields the same observations when interpreted from the model's initial state and the sut's initial state. Cleans up after itself by calling Spec.cleanup.

Sourceval agree_test : count:int -> name:string -> QCheck.Test.t

An actual agreement test (for convenience). Accepts two labeled parameters: count is the test count and name is the printed test name.

Sourceval neg_agree_test : count:int -> name:string -> QCheck.Test.t

A negative agreement test (for convenience). Accepts two labeled parameters: count is the test count and name is the printed test name.
