@Override
    public Scenario<GIVEN_WHEN, GIVEN_WHEN, THEN> getScenario() {
        return (Scenario<GIVEN_WHEN, GIVEN_WHEN, THEN>) scenarioRule.getScenario();
    }

@param <GIVEN_WHEN> the stage class that contains the step definitions for given and when
@param <THEN> the stage class that contains the step definitions for then
