Description
What's the problem this feature will solve?
The -r flag controls both summary report and output capture reporting.
Really, it'd be nice to have those separate.
For large tests suites, -ra is often used to report the reason for non-passing tests per test in the summary.
For small test suites, -rA is common, as it lists all tests in the summary, including passing.
However, it also reports captured output.
I know there is --show-capture=no. But that turns off showing captured output for failures also.
Describe the solution you'd like
I'd like a way to separate -r functionality into:
- which outcomes should show summary reports
- which outcomes should show captured output
However, I know -r is legacy and the default behavior can't change.
But maybe some other way to turn off capture for everything.
These are verbose, but maybe --capture-on that takes chars that matches the -r chars.
So -rA --capture-on=a would report on all, including passing, but capture on all except passing.
The default behavior could stay with "whatever -r" is set to.
Alternative Solutions
Different flag or option name is ok.
Additional context
We had a similar issue with tracebacks, and added --xfail-tb to deal with that.
But output capture is still an issue, and a surprising one, as the documentation for -rA doesn't mention that it turns on passing output capture.

Research direction
Start by tracing pytest's -r, -rA, -ra, --show-capture, and --xfail-tb option behavior. Define how summary reporting and captured-output reporting should be selected independently while preserving the current default behavior. Done means passing-test summaries can be shown without passing captured output, while failure output remains available.
