The capture_stdout decorator in pandas/util/testing.py is a good place to start.

Hello @WillAyd @gfyoung I am looking to make my first open source contribution.

Would you mind explaining a little more on the issue. What is the STDOUT supposed to be captured to ( a variable ?).

[gfyoung]

@rcromo : Thanks for wanting to contribute! Let me answer your question:

STDOUT is not a variable. It's the name of the location (or stream, rather) where anything you print goes. What we want to do is redirect the print statements to another location that doesn't cause them to be displayed in the terminal output on Travis.

@gfyoung Thanks for the response. I know the STDOUT isn't a variable, I meant to ask where specifically does it have to be redirected to.

Ah, gotcha. Per my comment above, see how we implemented capture_stdout in pandas/util/testing.py. There is no specific place in this case.
