Signature

exception ThreadNotFinished

val arb_cmds_triple : 
  int ->
  int ->
  (Spec.cmd list * Spec.cmd list * Spec.cmd list) QCheck.arbitrary

arb_cmds_triple seq_len conc_len generates a cmd triple with at most seq_len sequential commands and at most conc_len concurrent commands each. All cmds are generated with Spec.arb_cmd. arb_cmds_triple catches and ignores generation-time exceptions arising from Spec.next_state.

val interp_sut_res : Spec.sut -> Spec.cmd list -> (Spec.cmd * STM.res) list

interp_sut_res sut cs interprets the commands cs over the system sut and returns the list of corresponding Spec.cmd and result pairs.

val agree_prop_conc : (Spec.cmd list * Spec.cmd list * Spec.cmd list) -> bool

Concurrent agreement property based on Thread

val agree_test_conc : count:int -> name:string -> QCheck.Test.t

Concurrent agreement test based on Thread which combines repeat and ~retries

val neg_agree_test_conc : 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.
