## 📊 Coverage Analysis
### Viewing Coverage Reports
```bash
# Generate HTML report
pytest --cov-report=html
open htmlcov/index.html
# Terminal report with missing lines
pytest --cov-report=term-missing
# XML report for CI/CD
pytest --cov-report=xml
```
### Coverage Targets
| Module | Target | Current |
|--------|---------|---------|
| `fastmcp_server.py` | 74% | Current |
| `config.py` | 90% | 96% |
| **Overall** | 80% | 82% |
### Improving Coverage
To improve test coverage:
1. **Identify uncovered lines:**
```bash
pytest --cov-report=term-missing | grep "TOTAL"
```
2. **Add tests for missing paths:**
- Error conditions
- Edge cases
- Exception handling
3. **Run coverage-specific tests:**
```bash
pytest tests/test_coverage.py -v
```
## ⚡ Performance Testing
### Benchmark Tests
Performance tests validate response times:
```python
# Example performance test
async def test_search_performance():
"""Verify search performance under 10 seconds."""
start_time = time.time()
async with Client(mcp) as client:
await client.call_tool("search_content", {
"query": "*",
"max_results": 10
})
duration = time.time() - start_time
assert duration < 10.0, f"Search took {duration:.2f}s, expected <10s"
```
### Performance Targets
| Operation | Target | Typical |
|-----------|---------|---------|
| Search | <10s | 2-5s |
| Upload | <30s | 5-15s |
| Download | <15s | 3-8s |
| Properties | <5s | 1-3s |
| Concurrent (5x) | <15s | 8-12s |
### Running Performance Tests
```bash
# Run performance suite
python scripts/run_tests.py performance
# Run with timing details
pytest -m performance --duration=10
```
## 🔨 Test Development
### Adding New Tests
1. **Choose the right test type:**
- Unit: Fast feedback, mocked dependencies
- Integration: Real server interaction
- Coverage: Edge cases and errors
2. **Follow naming conventions:**
```python
# Unit tests
async def test_tool_name_success():
async def test_tool_name_error_case():
# Integration tests
async def test_live_tool_integration():
# Coverage tests
async def test_edge_case_handling():
```
3. **Use appropriate fixtures:**
```python
# Mock fixtures for unit tests
def test_with_mock_client(mock_alfresco_client):
pass
# Real client for integration
def test_with_real_client(alfresco_client):
pass
```
### Test Patterns
**Arrange-Act-Assert Pattern:**
```python
async def test_example():
# Arrange: Set up test data
mock_client = create_mock_client()
test_params = {"query": "test"}
# Act: Execute the function
result = await tool.execute(mock_client, test_params)
# Assert: Verify the outcome
assert "expected result" in result
mock_client.method.assert_called_once()
```
**Error Testing Pattern:**
```python
async def test_error_handling():
# Arrange: Set up error condition
mock_client = Mock()
mock_client.method.side_effect = ConnectionError("Network error")
# Act & Assert: Verify error handling
result = await tool.execute(mock_client, {})
assert "❌ Error:" in result
assert "Network error" in result
```
### Mocking Best Practices
```python
# Good: Mock at the right level
@patch('alfresco_mcp_server.fastmcp_server.ClientFactory')
async def test_with_proper_mock(mock_client_class):
mock_instance = mock_client_class.return_value
mock_instance.search.return_value = test_data
# Test uses mocked instance
result = await search_tool.execute(mock_instance, params)
# Good: Use realistic test data
def create_mock_search_results(count=3):
return [
{
"entry": {
"id": f"test-id-{i}",
"name": f"test-doc-{i}.txt",
"nodeType": "cm:content",
"properties": {
"cm:title": f"Test Document {i}",
"cm:created": "2024-01-15T10:30:00.000Z"
}
}
}
for i in range(count)
]
```
## 🚨 Troubleshooting Tests
### Common Issues
**Test Failures:**
1. **Connection Errors in Integration Tests:**
```bash
# Check Alfresco is running
curl -u admin:admin http://localhost:8080/alfresco/api/-default-/public/alfresco/versions/1/nodes/-root-
# Verify environment variables
echo $ALFRESCO_URL
echo $ALFRESCO_USERNAME
```
2. **Import Errors:**
```bash
# Reinstall in development mode
pip install -e .
# Check Python path
python -c "import alfresco_mcp_server; print(alfresco_mcp_server.__file__)"
```
3. **Coverage Too Low:**
```bash
# Run coverage tests specifically
pytest tests/test_coverage.py
# Check what's missing
pytest --cov-report=term-missing
```
**Performance Issues:**
1. **Slow Tests:**
```bash
# Profile test execution time
pytest --duration=10
# Run only fast tests
pytest -m "not slow"
```
2. **Timeout Errors:**
```bash
# Increase timeout for integration tests
pytest --timeout=60 tests/test_integration.py
```
### Debugging Tests
```bash
# Run with pdb debugger
pytest --pdb tests/test_file.py::test_function
# Show full output (don't capture)
pytest -s tests/test_file.py
# Show local variables on failure
pytest --tb=long
# Run single test with maximum verbosity
pytest -vvv tests/test_file.py::test_function
```
