notRecorded property
Every exchange ScenarioNetwork.replay refused because the recording
does not hold it, across every branch, as METHOD url in the order they
were first asked for.
What fails the scenario when its body is over. A refused replay is a
picture of the recording's gap rather than of the app, and a scenario
that chose replay chose to have the network.
Implementation
Iterable<String> get notRecorded => _notRecorded;
