# Testing Tasks

## Purpose

This directory contains tasks related to test creation, test coverage improvements, and testing infrastructure for the LLM AnyGate project. These tasks ensure code quality and reliability through comprehensive testing.

## Testing Categories

### Unit Tests
- Individual function/method testing
- Class behavior verification
- Edge case handling
- Error condition testing

### Integration Tests
- Component interaction testing
- API endpoint testing
- Database integration
- External service mocking

### End-to-End Tests
- Complete workflow testing
- User journey validation
- System behavior verification

### Performance Tests
- Load testing
- Benchmark creation
- Memory profiling
- Response time testing

## Task Template

```markdown
# Test: [Component/Feature]

## HEADER
- **Purpose**: Test [what aspect]
- **Status**: pending
- **Date**: [YYYY-MM-DD]
- **Dependencies**: [Component to test]
- **Target**: [Who will write tests]

## Testing Scope
[What needs to be tested and why]

## Current Coverage
- Current: [X%]
- Target: [Y%]
- Gap: [Missing test areas]

## Test Plan

### Unit Tests
```python
# test_component.py
import pytest
from llm_anygate import Component

class TestComponent:
    def test_normal_operation(self):
        """Test normal behavior."""
        pass
    
    def test_edge_case(self):
        """Test edge conditions."""
        pass
    
    def test_error_handling(self):
        """Test error scenarios."""
        pass
```

### Integration Tests
```python
# test_integration.py
@pytest.mark.asyncio
async def test_component_integration():
    """Test component interactions."""
    pass
```

## Test Cases
- [ ] Test case 1: [Description]
  - Input: [Test input]
  - Expected: [Expected output]
- [ ] Test case 2: [Description]
- [ ] Test case 3: [Description]

## Mocking Strategy
- Mock [external service]
- Fixture for [component]
- Test data for [scenario]

## Verification
- [ ] Tests pass locally
- [ ] CI/CD passes
- [ ] Coverage increased
- [ ] No flaky tests

## Coverage Report
```
Module          Coverage
-----------------------
core.py         85% → 95%
providers.py    70% → 90%
config.py       60% → 85%
```
```

## Example Test Tasks

### Core Components
- `task-test-gateway-routing.md` - Gateway routing logic
- `task-test-provider-interface.md` - Provider abstraction
- `task-test-config-validation.md` - Configuration validation

### Provider Tests
- `task-test-openai-provider.md` - OpenAI integration
- `task-test-anthropic-provider.md` - Anthropic integration
- `task-test-provider-fallback.md` - Fallback mechanism

### API Tests
- `task-test-api-endpoints.md` - REST API testing
- `task-test-authentication.md` - Auth flow testing
- `task-test-rate-limiting.md` - Rate limit testing

### Performance Tests
- `task-benchmark-gateway.md` - Gateway performance
- `task-load-test-providers.md` - Provider load testing
- `task-memory-profiling.md` - Memory usage testing

```

## Testing Best Practices

### Test Naming
- Use descriptive names: `test_provider_handles_timeout_gracefully`
- Group related tests in classes
- Use docstrings to explain complex tests

### Test Structure
```python
def test_feature():
    # Arrange
    setup_test_data()
    
    # Act
    result = perform_action()
    
    # Assert
    assert result == expected
```

### Fixtures
```python
@pytest.fixture
def mock_provider():
    """Reusable mock provider."""
    return MockProvider()
```

### Parametrized Tests
```python
@pytest.mark.parametrize("input,expected", [
    ("test1", "result1"),
    ("test2", "result2"),
])
def test_multiple_cases(input, expected):
    assert process(input) == expected
```

## Coverage Goals

- **Minimum**: 80% overall coverage
- **Target**: 90% for core modules
- **Critical**: 95% for security/auth

## Best Practices

1. Write tests before fixing bugs
2. Test both success and failure paths
3. Use meaningful test data
4. Keep tests independent
5. Mock external dependencies
6. Use fixtures for common setup
7. Run tests frequently during development
