Automation Testing of GoJS related stuff

Can someone help me automate testing of GoJS related stuff?
We need FE developer with VERY good experience with GoJS library.
GoJS testing automation experience would be 100% match for the need.

It might be helpful to be more specific about the technologies you expect to use for testing your app. Or that you don’t care at all which technologies are used, as long as the testing is good.

Searching this forum might help answer questions about certain testing technologies.
