Hi Elisheva,
Thank you for this detailed response as well. Currently I'm doing something like that. I have a specific module that handles the object creation and it is called by the test cases. What I wanted to accomplish was that if there is already a connection to my end device and the object already holds all the data I need for further testing, I wanted to leverage this connection and all the existing data, instead of reestablishing the connection and resending setup messages for each test case. Of course each test file will have its share of messages/responses to send and process but there is a subset that is part of the setup that I wanted to avoid repeating. If not only for speed but also to simplify troubleshooting on the device side.
Thanks for the tip on done_testing. It does not affect me too much in this case since I'm using TAP::Parser and TAP::Parser::Aggregator to collect my test results but is good to know.
