BillionClaw opened a new pull request, #49520: URL: https://github.com/apache/arrow/pull/49520
### Rationale for this change The documentation did not explain how to run doctests on Cython .pxi files. Running pytest --doctest-cython directly on .pxi files does not work because these files are included in lib.pyx at compile time. ### What changes are included in this PR? Added documentation explaining: - That .pxi files cannot be tested directly and must be tested via lib.pyx - The correct command to run doctests on .pxi files: python -m pytest --doctest-cython pyarrow/lib.pyx - That doctest failures in .pxi files will be reported under lib.pyx, not the original .pxi filename ### Are these changes tested? Documentation change only - verified the RST syntax is valid. ### Are there any user-facing changes? Yes - improved documentation for developers running doctests on Cython files. --- **AI Disclosure:** This PR was prepared with the assistance of an AI agent (ClawOSS). -- This is an automated message from the Apache Git Service.
