PostconditionViolation

Rasuvaeff\PropertyTesting\StateMachine\PostconditionViolation

Class — Package: property-testing-core — Source — Version: v0.1.0-12-g86ead85

Extends: RuntimeException

Implements: Stringable, Throwable

Thrown by StateMachine::check() when a command's Command::postCondition() returns false.

Carries the executed trace (command labels up to and including the failing one), the failing command, and the pre-state model and observed result, so the property runner surfaces exactly which step of the sequence broke.
