From a6a7ee1e8948981e6764eb6628983f59a2ad6872 Mon Sep 17 00:00:00 2001 From: Arif Dogan Date: Tue, 11 Nov 2025 04:01:17 +0100 Subject: [PATCH 1/9] feat: add comprehensive test suite and production-ready tooling Add 96 comprehensive tests covering all core modules with pytest markers (unit/integration/security). Add test coverage setup with 90% target. Create shared test fixtures. Add development tooling: Makefile, pre-commit hooks, enhanced CI/CD workflow. Add security scanning and quality gates. Fix all lint and type checking issues. --- .coveragerc | 30 +++ .github/PULL_REQUEST_TEMPLATE.md | 52 +++++ .github/workflows/ci.yml | 108 +++++++-- .pre-commit-config.yaml | 72 ++++++ Makefile | 79 +++++++ PRODUCTION_READINESS_SUMMARY.md | 338 +++++++++++++++++++++++++++ fastapi_radar/__init__.py | 2 +- fastapi_radar/api.py | 74 ++---- fastapi_radar/background.py | 2 +- fastapi_radar/capture.py | 19 +- fastapi_radar/middleware.py | 26 +-- fastapi_radar/models.py | 41 ++-- fastapi_radar/radar.py | 18 +- fastapi_radar/tracing.py | 23 +- mypy.ini | 31 ++- pyproject.toml | 72 +++++- pytest.ini | 24 ++ tests/conftest.py | 179 +++++++++++++++ tests/test_api_endpoints.py | 0 tests/test_async_radar.py | 7 +- tests/test_authentication.py | 312 +++++++++++++++++++++++++ tests/test_background.py | 178 +++++++++++++++ tests/test_capture.py | 226 ++++++++++++++++++ tests/test_integration.py | 377 +++++++++++++++++++++++++++++++ tests/test_middleware.py | 295 ++++++++++++++++++++++++ tests/test_models.py | 310 +++++++++++++++++++++++++ tests/test_radar.py | 261 +++++++++++++++++---- tests/test_tracing.py | 254 +++++++++++++++++++++ tests/test_utils.py | 257 +++++++++++++++++++++ 29 files changed, 3445 insertions(+), 222 deletions(-) create mode 100644 .coveragerc create mode 100644 .github/PULL_REQUEST_TEMPLATE.md create mode 100644 .pre-commit-config.yaml create mode 100644 Makefile create mode 100644 PRODUCTION_READINESS_SUMMARY.md create mode 100644 pytest.ini create mode 100644 tests/conftest.py create mode 100644 tests/test_api_endpoints.py create mode 100644 tests/test_authentication.py create mode 100644 tests/test_background.py create mode 100644 tests/test_capture.py create mode 100644 tests/test_integration.py create mode 100644 tests/test_middleware.py create mode 100644 tests/test_models.py create mode 100644 tests/test_tracing.py create mode 100644 tests/test_utils.py diff --git a/.coveragerc b/.coveragerc new file mode 100644 index 0000000..e75b506 --- /dev/null +++ b/.coveragerc @@ -0,0 +1,30 @@ +[run] +source = fastapi_radar +omit = + */tests/* + */test_*.py + */__pycache__/* + */site-packages/* + */dashboard/node_modules/* + */dashboard/dist/* + +[report] +precision = 2 +show_missing = True +skip_covered = False +exclude_lines = + pragma: no cover + def __repr__ + raise AssertionError + raise NotImplementedError + if __name__ == .__main__.: + if TYPE_CHECKING: + @abstractmethod + @abc.abstractmethod + pass + +[html] +directory = htmlcov + +[xml] +output = coverage.xml diff --git a/.github/PULL_REQUEST_TEMPLATE.md b/.github/PULL_REQUEST_TEMPLATE.md new file mode 100644 index 0000000..dfca173 --- /dev/null +++ b/.github/PULL_REQUEST_TEMPLATE.md @@ -0,0 +1,52 @@ +# Pull Request + +## Description + + +## Type of Change + + +- [ ] Bug fix (non-breaking change which fixes an issue) +- [ ] New feature (non-breaking change which adds functionality) +- [ ] Breaking change (fix or feature that would cause existing functionality to not work as expected) +- [ ] Documentation update +- [ ] Performance improvement +- [ ] Code refactoring +- [ ] Test coverage improvement + +## Related Issue + +Fixes #(issue number) + +## Changes Made + + +- +- +- + +## Testing + + +- [ ] All existing tests pass +- [ ] New tests added for new functionality +- [ ] Manual testing completed +- [ ] Test coverage >= 90% + +## Checklist + + +- [ ] My code follows the project's code style +- [ ] I have performed a self-review of my code +- [ ] I have commented my code, particularly in hard-to-understand areas +- [ ] I have made corresponding changes to the documentation +- [ ] My changes generate no new warnings +- [ ] I have added tests that prove my fix is effective or that my feature works +- [ ] New and existing unit tests pass locally with my changes +- [ ] Any dependent changes have been merged and published + +## Screenshots (if applicable) + + +## Additional Notes + diff --git a/.github/workflows/ci.yml b/.github/workflows/ci.yml index 42334bd..0852366 100644 --- a/.github/workflows/ci.yml +++ b/.github/workflows/ci.yml @@ -10,55 +10,135 @@ jobs: test: runs-on: ubuntu-latest strategy: + fail-fast: false matrix: python-version: ['3.9', '3.10', '3.11', '3.12'] steps: -
