"""Test for data switch between WiFi and Cell. DUT go in and out WiFi
coverage for multiple times.
Steps:
1. Set WiFi and Cellular signal to good (attenuation value to MIN).
2. Make sure DUT get Cell data coverage (LTE) and WiFi connected.
3. Set WiFi RSSI to MAX (WiFi attenuator value to MIN).
4. Verify DUT report WiFi connected and Internet access OK.
5. Set WiFi RSSI to MIN (WiFi attenuator value to MAX).
6. Verify DUT report Cellular Data connected and Internet access OK.
7. Repeat Step 3~6 for stress number.
Expected Results:
4. DUT report WiFi connected and Internet access OK.
6. DUT report Cellular Data connected and Internet access OK.
7. Stress test should pass.
Returns:
True if Pass. False if fail.
