* csv: quote embedded CR/LF under QUOTE_MINIMAL with custom lineterminator QUOTE_MINIMAL rows were serialized by csv-core, which only quotes bytes registered for the configured terminator, so fields containing '\r' or '\n' were left unquoted when the lineterminator was not CR/LF (e.g. '!' or '\0'). Route QUOTE_MINIMAL through a hand-written path that uses field_needs_quotes, which always treats '\r'/'\n' as needing quotes. A single empty field is quoted and an empty row emits only the terminator, matching CPython. QUOTE_ALL / QUOTE_NONNUMERIC still use csv-core. Assisted-by: Claude Code:claude-opus-4-8 * csv: unmark now-passing writer tests test_write_iterable and test_write_empty_fields pass with the QUOTE_MINIMAL writer fix (empty rows no longer emit an empty field).

Test snippets
This directory contains two sets of test snippets which can be run in Python.
The snippets/ directory contains functional tests, and the benchmarks/
directory contains snippets for use in benchmarking RustPython's performance.
Setup
Our testing depends on pytest, which you can install using pip.
Running
Simply run pytest -v in this directory, and the tests should run (and hopefully
pass). If it hangs for a long time, that's because it's building RustPython in
release mode, which should take less time than it would to run every test
snippet with RustPython compiled in debug mode.
