Enabling 'tee-sys' from within fixture/test?

[Tbruno25]

I've got a certain test which relies on --capture=tee-sys being enabled.

Wondering if there is any way of enabling this functionality from a module level regardless of whether the option was set or not at the cli level?

Hi @Tbruno25,

This is not currently possible I'm afraid, --capture is set in the CaptureManager right at the start of the session, and can't be changed afterwards.

I can think of these solutions to at least remedy the situation:

1. Check that during pytest_configure to at least error out with an appropriate message, rather than having tests failing.
2. Skip those tests which require tee-sys if --capture is not the required mode.
