Creates a new action command with 3 arbitraries.

Parameters:

  • description: The description of the action.
  • arbitrary1: The arbitrary used to generate the first value.
  • arbitrary2: The arbitrary used to generate the second value.
  • arbitrary3: The arbitrary used to generate the third value.
  • run: A function to perform the action.
  • precondition: A function to test the precondition of the action.
  • postcondition: A function to test the postcondition of the action.

  FutureOr<bool> Function(State, T1, T2, T3, R)? postcondition,
}) : super(
