This directory is organized as follows:
- `tests/unit/`: fast unit tests with mocks
- `tests/integration/`: optional integration tests that may require `pykeepass` and a Python environment
- `tests/unit/`: fast unit tests for the native TypeScript API
- `tests/integration/`: optional compatibility tests that may use `pykeepass`
- `tests/fixtures/`: bundled KeePass databases and matching JSON credentials/content files
## Conventions
- Use `*.test.ts` filenames.
- Keep unit tests isolated and fast.
- Prefer mocking the Python bridge in unit tests.
- Put environment-dependent checks in `tests/integration/`.
- Put compatibility or environment-dependent checks in `tests/integration/`.
- Keep fixture-driven expectations aligned with the matching `*.kdbx.json` file.
- Integration tests should skip or self-report when prerequisites are missing.

# Integration Tests
This directory is reserved for tests that require external dependencies or a Python environment with `pykeepass` installed.
This directory is reserved for compatibility tests and scenarios that may use `pykeepass`.
## Conventions
- Use `*.test.ts` filenames.
- Keep tests here isolated from unit tests.
- Prefer explicit setup/skip logic when runtime dependencies are missing.
- Integration tests should verify the real KeePass bridge when `pykeepass` and fixture credentials are available.
- Prefer explicit setup/skip logic when optional dependencies are missing.
- Integration tests should verify native behavior against the compatibility reference when available.
- Prefer fixtures in `tests/fixtures/` and keep expectations aligned with the companion JSON file.
