Hi Zhenyu,
  I think the biggest concern we need to focus on is the short connection 
test between the neighboring pins on the hybrid connector.
  For the open connection test, I think we can test the connection of voltage 
and some clock pins, such as VSS, VDD, GND, SUB, CLK, TRG, SCLK, and SDA. The 
detailed information of the test pins can be found in the attachment.
  Please let me know if you have any other suggestions.

Best,
Jianing
