Harden the skip_reason_plugin to reject bare @pytest.mark.skip at
collection time with pytest.UsageError instead of warnings.warn().
Add test/pylib_test/test_no_bare_skips.py with three guard tests:
- AST scan for bare pytest.skip() runtime calls
- Real pytest --collect-only against all Python test directories
Add skip_reason_plugin.py — a framework-agnostic pytest plugin that
provides typed skip markers (skip_bug, skip_not_implemented, skip_slow,
skip_env) so that the reason a test is skipped is machine-readable in
JUnit XML and Allure reports. Bare untyped pytest.mark.skip now
triggers a warning (to become an error after full migration). Runtime
skips via skip() are also enriched by parsing the [type] prefix from
the skip message.
The plugin is a class (SkipReasonPlugin) that receives the concrete
SkipType enum and an optional report_callback from conftest.py, keeping
it decoupled from allure and project-specific types.
Extract SkipType enum and convenience runtime skip wrappers (skip_bug,
skip_env, etc.) into test/pylib/skip_types.py so callers only need a
single import instead of importing both SkipType and skip() separately.
conftest.py imports SkipType from the new module and registers the
plugin instance unconditionally (for all test runners).
New files:
- test/pylib/skip_reason_plugin.py: core plugin — typed marker
processing, bare-skip warnings, JUnit/Allure report enrichment
(including runtime skip() parsing via _parse_skip_type helper)
- test/pylib/skip_types.py: SkipType enum and convenience wrappers
(skip_bug, skip_not_implemented, skip_slow, skip_env)
- test/pylib_test/test_skip_reason_plugin.py: 17 pytester-based
test functions (51 cases across 3 build modes) covering markers,
warnings, reports, callbacks, and skip_mode interaction
Infrastructure changes:
- test/conftest.py: import SkipType from skip_types, register
SkipReasonPlugin with allure report callback
- test/pylib/runner.py: set SKIP_TYPE_KEY/SKIP_REASON_KEY stash keys
for skip_mode so the report hook can enrich JUnit/Allure with
skip_type=mode without longrepr parsing
- test/pytest.ini: register typed marker definitions (required for
--strict-markers even when plugin is not loaded)
Migrated test files (representative samples):
- test/cluster/test_tablet_repair_scheduler.py:
skip -> skip_bug (#26844), skip -> skip_not_implemented
- test/cqlpy/.../timestamp_test.py: skip -> skip_slow
- test/cluster/dtest/schema_management_test.py: skip -> skip_not_implemented
- test/cluster/test_change_replication_factor_1_to_0.py: skip -> skip_bug (#20282)
- test/alternator/conftest.py: skip -> skip_env
- test/alternator/test_https.py: use skip_env() wrapper
