To test an experience, you need to first ensure that you are within the time frame that the experience will be active in. If necessary, you can temporarily reset the experience's time frame to an earlier date.
You then need to follow the components in the experience and exercise each portion of it. As you meet the requirements of each component, you should be able to progress to the next component.
If you set the time frame to any earlier start date, remember to reset the start date when you are done testing.
