CARD TITLE (intent, not commit subject): distrust-green gate: 0-collected-with-defined-tests must be a violation, not "skipping check" (supersedes PR #2431)

Autonomous build of board card tsk-zq24je.

REVISION: built on exec/tsk-prrt56 (cut at d172601e0ed8474004b0bef418df3ae0cad4dca4), not on dev. That branch's
commits are ancestors of this one and the Files: list below is the diff SINCE it,
so this PR shows the revision alone while carrying the original work. Verified by
git merge-base --is-ancestor before the PR was opened.

AST-count defined test functions per changed file; if defined_tests > 0
but pytest collected 0 outcomes, treat as a violation instead of
skipping clean. This closes the 0-collected-with-defined-tests gap
in the live distrust-green gate.

Summary by CodeRabbit

  • Bug Fixes

    • Improved test validation to detect defined tests that were not collected or executed.
    • Files without defined tests continue to generate warnings and are skipped appropriately.
    • Preserved support for intentional skip waivers and partial-skip scenarios.
  • Tests

    • Added coverage for synchronous, asynchronous, class-based, invalid, missing, and empty test files.
  • Documentation

    • Added a changelog entry describing the updated test validation behavior.

📝 Walkthrough

Walkthrough

The skip check now counts test_* functions with AST parsing. It fails files that define tests but collect no outcomes. Tests cover discovery, parsing errors, skip states, and waivers. A changelog entry documents the behavior.

Merge Risk: 🔵 Low · up to f15ee

The gate now rejects files with defined tests when zero tests are collected, but the final failure summary can still report zero failing files. This bounded reporting issue is mergeable with explicit owner follow-up.

WARNING: Substring match in has_escape_hatch allows false waivers

if basename in trailer_claim: matches any trailer containing the basename as a substring. For example, a trailer for test_foo_other.py would falsely waive the check for test_foo.py because test_foo.py is contained in test_foo_other.py. Use a stricter match (e.g. split on , and compare exact basenames, or require word boundaries).

WARNING: Double-counting of test outcomes when both summary and outcome_lines match

total = passed + skipped + failed at line 102 adds summary counts, then the loop at line 116 increments total += 1 for every matched outcome line. When pytest emits both a summary line and individual outcome lines (e.g. in verbose mode or with certain flags), the counts are doubled, producing incorrect totals. The fallback block at line 125 only handles the case where total is already 0, not this double-counting scenario.

SUGGESTION: Regex does not match pytest node IDs with :: separator

The pattern r"^([\w\.-]+)\s+(SKIPPED|FAILED|PASSED)\s*$" matches only names composed of word characters, dots, and hyphens. Pytest node IDs like tests/test_foo.py::test_name contain ::, so the regex will fail to capture them. While -q may suppress individual lines, this regex would silently miss outcome lines in verbose output.

Reviewed vs card tsk-zq24je contract + Kilo 3 findings. One semantic conflict found and fixed forward (f15eea5).

Contract: delivered. AST count (_count_defined_tests, module + class methods via ast.walk, AsyncFunctionDef covered) + total==0 and defined_tests>0 → FAIL branch; defined_tests==0 stays a warning. The old superseded gate files are NOT resurrected. Red proof measured by me on the merge result: PR's test file vs pre-fix dev script = 9 failed (incl. test_zero_collected_with_defined_tests_is_not_clean); post-fix 12/12 pass.

Semantic conflict (stale-base class, same as #2460): branch was cut at d172601, before c89310f's waiver exact-match landed on dev via #2456. Branch+dev merged cleanly but test_all_skips_waived_by_escape_hatch failed on the merge result: the test's trailer claimed the full path tests/test_foo.py while dev's has_escape_hatch requires the exact basename. Test bug, not code bug — fixed the trailer to test_foo.py and merged dev in (c9d8b18 + f15eea5), 12/12 green on the true merge tree.

Kilo dispositions: (223 substring waiver) — described the pre-c89310fb copy on the branch; the merge takes dev's exact-match version, already fixed. (102 double-counting) — previously declined verdict-invariant on #2456; under the new rule it can only inflate total away from 0, never toward it, so it cannot manufacture a violation. (107 :: node-ID regex) — real gap in the outcome-line regex but non-blocking: the summary-line parse is the primary path and always matches when tests ran; outcome lines are a secondary counter.

Design note: the 0-collected violation is deliberately NOT waivable by Tests-Skipped-Intentionally — that trailer's semantics are "skipped on purpose", not "failed to collect"; the remedy for collection failure is fixing collection.

APPROVED pending green on f15eea5. Merge chain: on green, merge + close tsk-zq24je.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Report zero-collected violations in the final error summary.

If this branch fails, all_skip_files excludes the failing file. The final output at Line 315 can then report zero failing files. Use a generic failure summary, or count zero-collected violations separately.

Proposed fix
     if any_fail:
-        print(f"\n::error:: {all_skip_files} file(s) have all tests skipping — see above for details")
+        print("\n::error:: skip validation failed — see above for details")

Confirmed by measured run (module loaded standalone, one zero-collected file {total:0, defined_tests:7}): exit code is correct (main_rc=1) but the final annotation reads ::error:: 0 file(s) have all tests skipping. Message-accuracy defect only — the gate itself fails correctly, so this doesn't block the merge. Carded as tsk-syhpdp (red-first: a test asserting the final ::error line names zero-collected violations, deriving summary and any_fail from one source so they can never disagree).

@jaylfc Thanks for the measured confirmation. The gate behavior is correct. The final ::error summary is inaccurate for zero-collected violations.

The follow-up in tsk-syhpdp addresses the issue. I will keep this thread open until that change is implemented and tested.
