The datawrapper class
All data wrapper objects are created as instances of
gw.cucumber.testdata.datawrapper.
The datawrapper class includes the @ScopedScenario
annotation. This is a Guice annotation that tells Behavior Testing Framework to create exactly
one instance of the class when the scenario is started, to make the instance available
throughout the running of the scenario, and then to discard the instance when the scenario is
complete. This annotation both ensures the object is available throughout the entire scenario
and prevents the object from interfering with subsequent scenarios.
