Pytest 8 migration check — check pytest changes free

Flags pytest APIs removed in pytest 8 and pytest config keys that are silently ignored, with the replacement line and the version that removed each one. Runs entirely in your browser — nothing is uploaded.

Free here: Lint the pytest file you have open and see every removed API and every silently-ignored config key, each with the pytest version that removed it and the exact replacement line.. In the editor: Audit every test file, conftest.py and config file in the workspace in one pass and export the dated findings as Markdown or JSON you keep and paste into CI. — that part asks for a licence key.

Same engine as the VS Code extension, byte for byte.
