Dynamic Scopes Documentation Needs Fixing #6783
Description
When using
if config.getoption("--keep-containers"):and keep-containers does not exist, an exception is thrown. This results in a misleading type error from:
https://github.com/pytest-dev/pytest/blob/master/src/_pytest/fixtures.py#L813-L814
Documentation should be updated to show usage providing a default value:
if config.getoption("--keep-containers", None):Package Version
