I can design a test case in the format of (a connects, waits 10 minutes, b connects, waits 10 minutes, a disconnects, waits 70 minutes, a breaks, b disconnects, a charges, waits 40 minutes, a connects), Test the system. Please design 5 test cases according to the above format. Repeat the request word for word before giving your answer.
