tesserakit-tests

Audit a Python test suite for hygiene problems.

tessera-tests parses test files with ast (never imports or runs them), inventories the test functions and methods, and surfaces the tests that aren't really protecting anything: tests with no assertions, and tests that are skipped or expected to fail.

Audit

tessera tests audit --input . --output ./out/tests_pack

Test discovery follows pytest/unittest conventions: files named test_*.py / *_test.py or under a tests/ directory; functions named test*; methods named test* inside Test* classes.

Artifacts written:

tests.jsonl              one TestCase per test (asserts, skip/xfail/param flags)
index.md                 the test inventory
validation_report.md     hygiene findings
coverage_report.md       counts (skipped/xfail/parametrized/no-assert) + per-file
not_running.md           skipped + xfail tests (present but not protecting anything)

What it detects

• Assertions: assert statements, self.assert* calls, and pytest.raises/warns blocks.
• Markers: @pytest.mark.skip / skipif, xfail, parametrize (matched on the decorator name).

Findings

• no_assertion_test (warning) — a test with zero assertions that isn't skipped/xfail
• skipped_test (info) — a skipped test
• xfail_test (info) — an expected-failure test
• parse_error, no_tests_found
