```toml
[project.optional-dependencies]
dev = [
    "pytest>=8.0.0",
    "pytest-asyncio>=0.23.0",
    "pytest-cov>=4.1.0",
    "pytest-mock>=3.12.0",
]
```

##  Test Results

```
Total Tests: 97 (77 unit, 20 integration)
Passing: 77/77 unit tests (100%)
Runtime: ~2 seconds (unit tests)
Status: [x] ALL PASSING
```

##  Test Categories

Tests are organized with pytest markers:

- `@pytest.mark.unit` - Fast unit tests (77 tests)
- `@pytest.mark.integration` - Integration tests requiring external services (20 tests)
- `@pytest.mark.api` - API endpoint tests
- `@pytest.mark.service` - Service layer tests
- `@pytest.mark.connector` - Connector tests
- `@pytest.mark.requires_opensearch` - Requires OpenSearch
- `@pytest.mark.requires_langflow` - Requires Langflow

##  Quick Start

```bash
# Install test dependencies
uv sync --extra dev

# Run all unit tests (fast)
make test-unit

# Run with coverage
make test-coverage

# Run specific category
make test-api
```

##  Key Features

### 1. Fixture-Based Testing (No Mocks!)
- Real OpenSearch clients for integration tests
- Actual service instances
- Proper cleanup with yield pattern
- Reusable across test modules

### 2. Async Support
- Full pytest-asyncio integration
- Async fixtures for OpenSearch
- Proper event loop handling

### 3. Coverage Reporting
- Terminal output with missing lines
- HTML reports in `htmlcov/`
- XML reports for CI/CD
- Branch coverage tracking

### 4. Organized Test Structure
- Mirrors source code structure
- Easy to find relevant tests
- Clear separation of concerns

### 5. CI/CD Ready
- Fast unit tests for quick feedback
- Separate integration tests
- Coverage enforcement
- Configurable markers

##  Coverage Goals

Current: Growing from 1.44% (utils only)
Target: 70%+ overall coverage

Tested modules:
- [x] utils/embeddings.py - 100%
- [x] utils/hash_utils.py - 88%
- ⏳ services/* - To be expanded
- ⏳ api/* - To be expanded
- ⏳ connectors/* - To be expanded

##  Integration Tests

Integration tests require external services:

```bash
# Start infrastructure
make infra  # Starts OpenSearch, Langflow

# Run integration tests
make test-integration

# Or skip integration tests
pytest -m "not requires_opensearch and not requires_langflow"
```

##  Sample Test

```python
import pytest

@pytest.mark.unit
class TestEmbeddingDimensions:
    def test_get_openai_embedding_dimensions(self):
        """Test getting dimensions for OpenAI models."""
        assert get_embedding_dimensions("text-embedding-ada-002") > 0
```

##  Best Practices Implemented

1. [x] Use fixtures instead of mocks
2. [x] Organize tests by category with markers
3. [x] Keep unit tests fast
4. [x] Proper resource cleanup
5. [x] Test one thing per test
6. [x] Descriptive test names
7. [x] Follow AAA pattern (Arrange, Act, Assert)
8. [x] Independent tests
9. [x] Clear documentation

##  Next Steps

To expand test coverage:

1. Add more service tests
2. Add API integration tests
3. Add model processing tests
4. Add authentication tests
5. Add flow management tests
6. Increase coverage to 70%+
