When must members who will be unavailable during the testing cycle be ready to test?

The correct answer is that members must be ready to test before their departure. This ensures that all individuals are prepared for the testing process in advance, allowing them to fulfill their responsibilities and ensure that their absence does not affect the overall timing of the testing cycle. It also allows for a smoother transition and preparation for those who will be testing, maintaining the integrity and schedule of the testing environment.

Not being ready prior to departure can lead to logistical complications and might require making special arrangements that could disrupt the process. Therefore, thorough preparation before leaving is critical for all members involved in the promotion testing cycle.
