Unit Testing - Squelching Print Statements

[semireg]

I'm running unit tests within the unix port and some functions generate output via print. Is there a way to temporarily disable standard output from within the micropython environment, or redirect one output to another? I see sys.stderr and sys.stdout but it's not obvious how to manipulate them.

Is print(data, file=f) any help?

Is print(data, file=f) any help?

What if print is called internally?

This was a question in another thread

But... Help("modules") does show a list of frozen modules so the info is available in micropython (at least on esp32). Is there a way of redirecting the help output into a string for parsing (again on a esp32)?

but it definitely is a thread itself.
