From 36de8f0470386cae644f07ad1dd4cba55d3e8204 Mon Sep 17 00:00:00 2001 From: Andrew Kaszubski Date: Fri, 26 Dec 2025 10:40:30 +1100 Subject: [PATCH] feat(tests): add pytest conftest.py hierarchy with shared fixtures - Fixes #49 MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit - Created tests/conftest.py with 12 shared fixtures (environment mocks, LangChain/ChromaDB mocking, configuration) - Created tests/unit/conftest.py with 6 unit-specific fixtures (data vendors, sample data) - Created tests/integration/conftest.py with 2 integration fixtures (live ChromaDB, temp dirs) - Added pytest.ini with 7 custom markers (unit, integration, e2e, llm, chromadb, slow, requires_api_key) - Added tests/test_conftest_hierarchy.py with 83 tests validating fixture infrastructure - Updated docs/testing/README.md and writing-tests.md with fixture usage documentation 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 --- CHANGELOG.md | 20 + docs/testing/README.md | 114 ++++- docs/testing/writing-tests.md | 102 ++++ pytest.ini | 50 ++ tests/conftest.py | 385 +++++++++++++++ tests/integration/__init__.py | 1 + tests/integration/conftest.py | 87 ++++ tests/test_conftest_hierarchy.py | 796 +++++++++++++++++++++++++++++++ tests/unit/__init__.py | 1 + tests/unit/conftest.py | 185 +++++++ 10 files changed, 1718 insertions(+), 23 deletions(-) create mode 100644 pytest.ini create mode 100644 tests/conftest.py create mode 100644 tests/integration/__init__.py create mode 100644 tests/integration/conftest.py create mode 100644 tests/test_conftest_hierarchy.py create mode 100644 tests/unit/__init__.py create mode 100644 tests/unit/conftest.py diff --git a/CHANGELOG.md b/CHANGELOG.md index a86a14d9..4ff4835d 100644 --- a/CHANGELOG.md +++ b/CHANGELOG.md @@ -8,6 +8,16 @@ and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0 ## [Unreleased] ### Added +- pytest conftest.py hierarchy for organized test fixtures (Issue #49) + -
