# Testing signals — pytest-dev/pytest

Scanned commit 2887015cade4757385308e7a7d8083557fc637e2 (2026-09-29). Generated by codevetter codevetter 1.15.0 on 2026-10-02.

Source inspection; upstream code and tests were not executed.

Tests and CI were inspected, not executed; test existence is not a passing result. The repository tests pytest using pytest itself, including generated test projects through Pytester. Inspected cases exercise lifecycle reports, fixtures, assertion transforms, configuration, and cache boundaries. CI defines cross-platform and integration environments, but exclusions, disabled checks, and allowed failures limit what its configuration alone establishes.
- The default pytest configuration selects testing/, enables pytester, recognizes testing/python/*.py, and excludes example_scripts and plugins_integration from recursive discovery; these settings were inspected without running the suite. — [pyproject.toml#L422-L450](https://github.com/pytest-dev/pytest/blob/2887015cade4757385308e7a7d8083557fc637e2/pyproject.toml#L422-L450)
- testing/conftest.py stabilizes terminal width and color environment variables and classifies Pytester subprocess or pexpect cases as slower tests. — [testing/conftest.py#L30-L47](https://github.com/pytest-dev/pytest/blob/2887015cade4757385308e7a7d8083557fc637e2/testing/conftest.py#L30-L47) [testing/conftest.py#L50-L89](https://github.com/pytest-dev/pytest/blob/2887015cade4757385308e7a7d8083557fc637e2/testing/conftest.py#L50-L89)
- Runner tests inspect pass, failure, skip, setup failure, and teardown failure reports, including whether unsuccessful setup suppresses the call phase. — [testing/test_runner.py#L182-L207](https://github.com/pytest-dev/pytest/blob/2887015cade4757385308e7a7d8083557fc637e2/testing/test_runner.py#L182-L207) [testing/test_runner.py#L230-L284](https://github.com/pytest-dev/pytest/blob/2887015cade4757385308e7a7d8083557fc637e2/testing/test_runner.py#L230-L284)
- Fixture regression tests assert that class-scoped setup and teardown occur once across multiple tests and that scoped setup exceptions are cached without repeating finalization. — [testing/python/fixtures.py#L5464-L5495](https://github.com/pytest-dev/pytest/blob/2887015cade4757385308e7a7d8083557fc637e2/testing/python/fixtures.py#L5464-L5495) [testing/python/fixtures.py#L5498-L5535](https://github.com/pytest-dev/pytest/blob/2887015cade4757385308e7a7d8083557fc637e2/testing/python/fixtures.py#L5498-L5535)
- Assertion-rewrite helpers parse, transform, compile, and execute ASTs; configuration tests simulate pytest11 entry points and compare autoload disabling against explicit -p or PYTEST_PLUGINS enabling. — [testing/test_assertrewrite.py#L44-L74](https://github.com/pytest-dev/pytest/blob/2887015cade4757385308e7a7d8083557fc637e2/testing/test_assertrewrite.py#L44-L74) [testing/test_config.py#L1959-L2015](https://github.com/pytest-dev/pytest/blob/2887015cade4757385308e7a7d8083557fc637e2/testing/test_config.py#L1959-L2015)
- Cache tests cover parent and absolute path escapes, normalization within the cache, invalid JSON fallback, and mocked open/write/close failures; these assertions do not establish coverage of every filesystem race. — [testing/test_cacheprovider.py#L36-L69](https://github.com/pytest-dev/pytest/blob/2887015cade4757385308e7a7d8083557fc637e2/testing/test_cacheprovider.py#L36-L69) [testing/test_cacheprovider.py#L86-L131](https://github.com/pytest-dev/pytest/blob/2887015cade4757385308e7a7d8083557fc637e2/testing/test_cacheprovider.py#L86-L131)
- CI defines Windows, Ubuntu, macOS, CPython, PyPy, doctest, and plugin environments, installs built package artifacts through tox, and uploads coverage and JUnit reports; matrix.xfail jobs use continue-on-error. — [.github/workflows/test.yml#L58-L92](https://github.com/pytest-dev/pytest/blob/2887015cade4757385308e7a7d8083557fc637e2/.github/workflows/test.yml#L58-L92) [.github/workflows/test.yml#L258-L308](https://github.com/pytest-dev/pytest/blob/2887015cade4757385308e7a7d8083557fc637e2/.github/workflows/test.yml#L258-L308) [.github/workflows/test.yml#L310-L338](https://github.com/pytest-dev/pytest/blob/2887015cade4757385308e7a7d8083557fc637e2/.github/workflows/test.yml#L310-L338)
- Coverage configuration enables branches, parallel data, and subprocess patching, while tox separates doctests and plugin integrations; its BDD wallet command is commented out as broken by an internal fixture-map change. — [pyproject.toml#L521-L551](https://github.com/pytest-dev/pytest/blob/2887015cade4757385308e7a7d8083557fc637e2/pyproject.toml#L521-L551) [tox.ini#L65-L71](https://github.com/pytest-dev/pytest/blob/2887015cade4757385308e7a7d8083557fc637e2/tox.ini#L65-L71) [tox.ini#L177-L201](https://github.com/pytest-dev/pytest/blob/2887015cade4757385308e7a7d8083557fc637e2/tox.ini#L177-L201)
