Return Report of Procedural Functions using Decorators in Python

exc_report.ipynb

In the final version I pack the decorated functions return value, along with TestInfo object on return, if the decorated functions return value isn't None.
In this simplified version, I use the repr for readability in iPython. I need the TestInfo object to be returned even if there is a success to affirm that all functions were called without an exception.

I'm not sure how making the decorator a class will help. I need TestInfo to be a value-object returned to the caller to do analysis(this example is a proof of concept). I can define TestInfo class inside the decorator function exc_info however, which I think makes logical sense since nowhere else does it need to be used.
