I searched for debug, debugger, debugging in the academy link but did not find any courses covering debugger. I wish there was a video course which used non-trivial test examples to show debugging test cases and scripts in ReadyAPI. I wish the SmartBear team would make one. Currently, it looks like they only have very small documentation with only photos which is not very helpful. I think that debuggers are very important, especially when you are trying to diagnose an issue or understand someone else's code.
So, although someone marked one of the replies as an "accepted solution", I cannot consider this question as solved.
