# Skip tests in quarantine unless we explicitly focus on them.

# blocks unnecessarily.
# If quarantine is focussed, skip tests/contexts that have other metadata
# unless they're also focussed. This lets us run quarantined tests in a
# particular category without running tests in other categories.
# E.g., if a test is tagged 'smoke' and 'quarantine', and another is tagged
# 'ldap' and 'quarantine', if we wanted to run just quarantined smoke tests
# using `--tag quarantine --tag smoke`, without this check we'd end up
# running that ldap test as well.
# We could use an exclusion filter, but this way the test report will list
# the quarantined tests when they're not run so that we're aware of them
