In your \PCB\Logic directory of your board design you will find a file named Netlist.AUG
This is a Keyin netlist of the board that can be used for connection testing.
But there are easier options;
1. File > Export > General Interfaces, and use Generic ATE or Fabmaster
or my favorite
2. Use the Intelligent ODB++ output at Output > ODB++. This will provide your manufacturer with all that is required to build fabricate and test your board.
Good Luck,
