Python SDK tests (tests/)

pytest suite for the mem0/ package.

Commands

make install_all    # optional deps; several tests need them
make test           # pytest tests/
make test-py-3.9    # pin a Python version (3.9 through 3.12)

pytest tests/llms/test_openai.py::test_generate_response   # single test

Conventions

• Files are named test_<module>.py.
• Provider tests mirror the source tree: tests/<category>/<provider_name>/.
• pytest-mock for mocks, pytest-asyncio for the async surface.
• Ruff line length 120, matching mem0/. See ../mem0/AGENTS.md.
• Mock the provider SDK, never the code under test. A test that asserts the implementation back at itself is worse than no test.
• Bug fixes need a regression test that fails without the fix. Write it first and watch it fail.

Tests for other packages live with those packages: mem0-ts/ (jest), cli/python/tests/ (pytest), cli/node/ (vitest), and each directory under integrations/.
