capsys input disable

[georgeharker]

I have a baseline image diff test, for which I define an interactive mode, allowing diffs to be accepted or declined one by one. This works with X11 for the diff frontend and I block on the validation assert until input accepts or not (when in interactive mode).

I want to do a terminal version of this, but capsys.disable() doesn't pass through the in flag to suspend_capture here

pytest/src/_pytest/capture.py

Line 668 in 958981c

def suspend_capturing(self, in_: bool = False) -> None:

The intervening call to suspend_global_capture on multicapture here

pytest/src/_pytest/capture.py

Line 788 in 958981c

def suspend_global_capture(self, in_: bool = False) -> None:

does deal with input.

I think it would be as easy as modifying CaptureFixture to pass the boolean for input here

pytest/src/_pytest/capture.py

Line 987 in 958981c

def disabled(self) -> Generator[None]:

and wire it through here

pytest/src/_pytest/capture.py

Line 841 in 958981c

def global_and_fixture_disabled(self) -> Generator[None]:

with sensible current-behavior defaults.

I appreciate reading from stdin isn't a great idea for automated tests - this is intended for interactive maintenance of baseline image diffs only.

Meanwhile I can do the utterly horrible

from _pytest.capture import CaptureManager # ... capmanager: CaptureManager = capsys.request.config.pluginmanager.getplugin( "capturemanager" ) capmanager.suspend(in_=True) # ... capmanager.resume()

Any thoughts?
