Read tests to be executed from a file instead of from positional arguments

[levsa]

What's the problem this feature will solve?

I want to output a set of tests using pytest --collect-only -q to a file, and run selected subsets of it using pytest

Describe the solution you'd like

I want to collect tests to run and put them in a file (supported today, except -q or a similar flag to leave out all output except the actual test names)):

> pytest --collect-only -q > tests_to_run.txt

And then tell pytest to run tests listed in that file (or from stdin), like e.g.:

> pytest --from-file tests_to_run.txt

I want to run selected subsets of the tests to find bugs caused by interdependencies between a set of tests.

Hi,

We have an accepted issue about this #11871 so I'll close this one.
