We do not know if there are any complications with using Tessy. I will check with the internal software team to see what unit testing framework goes best with our tools.
As discussed with the team, for PSoC Creator we used our own custom unit testing framework when we build and test PSoC Creator. This was developed back in 2007, when we first started PSoC Creator.
Also, since there are a number of ways in which Tessy ( TESSY - Test System - Razorcat Development GmbH ), which is a very full featured system can be used. Can you please let us know how are you using it with your design and what are the particular issues that you are facing?
Thanks and Regards,
