This read-only TruthValue reports whether a one-time test trigger created to validate a schedule's behavior on demand, without waiting for its normal recurrence is configured to automatically delete itself after it runs. An administrator uses this to know whether they need to manually clean up the test trigger afterward or whether it will remove itself. For example, when an administrator wants to verify a new maintenance schedule actually fires correctly before relying on it, if this is true the admin doesn't need to remember to delete the test trigger once it has served its purpose.
