Hi,

As a system administrator I often have some small scripts/ programs that consume input and produce output for other system utilities. Something like `my_foo_program | awk ... | other_program`. As the tools write to STDOUT/STDERR, I haven't found a way to write unit tests for them. Should I write library instead? Is there any framework to write (smoke) tests that supports standard output devices?

Thanks for your reading.

So far I have refactored my code to use some public libraries. This allows me to write some unit tests. This requires a lot more work :)

Sorry for the noise.
