feat: implement test quality checks with enhanced guidance and external context integration

Browse Source 
- Added a new QualityConfig class to manage test quality check configurations.
- Implemented test quality checks for specific rules in test files, including prevention of conditionals, loops, and generic exceptions.
- Integrated external context providers (Context7 and Firecrawl) for additional guidance on test quality violations.
- Enhanced error messaging to provide detailed, actionable guidance for detected issues.
- Updated README_HOOKS.md to document new test quality features and configuration options.
- Added unit tests to verify the functionality of test quality checks and their integration with the pretooluse_hook.

- **Internal Duplicate Detection**: Analyzes code blocks within the same file
- **Complexity Analysis**: Prevents functions with excessive cyclomatic complexity
- **Modernization Checks**: Ensures code uses modern Python patterns and type hints

- **Smart Filtering**: Automatically skips test files and fixtures
- **Configurable Enforcement**: Strict denial, user prompts, or warnings
@@ -78,12 +79,99 @@ Set these environment variables to customize behavior:
| `QUALITY_VERIFY_NAMING` | true | Verify PEP8 naming conventions |
| `QUALITY_SHOW_SUCCESS` | false | Show success messages for clean files |
### Test Quality Features
| Variable | Default | Description |
|----------|---------|-------------|
| `QUALITY_TEST_QUALITY_ENABLED` | true | Enable test-specific quality checks for test files |
### External Context Providers
| Variable | Default | Description |
|----------|---------|-------------|
| `QUALITY_CONTEXT7_ENABLED` | false | Enable Context7 API for additional context analysis |
| `QUALITY_CONTEXT7_API_KEY` | "" | API key for Context7 service |
| `QUALITY_FIRECRAWL_ENABLED` | false | Enable Firecrawl API for web scraping examples |
| `QUALITY_FIRECRAWL_API_KEY` | "" | API key for Firecrawl service |
### Enforcement Modes
- **strict**: Deny writes with critical issues, prompt for warnings
- **warn**: Always prompt user to confirm when issues found
- **permissive**: Allow writes but display warnings
## Enhanced Error Messaging
When test quality violations are detected, the hook provides detailed, actionable guidance instead of generic error messages.
### Rule-Specific Guidance
Each violation type includes:
- **📋 Problem Description**: Clear explanation of what was detected
- **❓ Why It Matters**: Educational context about test best practices
- **🛠️ How to Fix It**: Step-by-step remediation instructions
- **💡 Examples**: Before/after code examples showing the fix
- **🔍 Context**: File and function information for easy location
### Example Enhanced Message

🚫 Conditional Logic in Test Function
📋 Problem: Test function 'test_user_access' contains conditional statements (if/elif/else).
❓ Why this matters: Tests should be simple assertions that verify specific behavior. Conditionals make tests harder to understand and maintain.
🛠️ How to fix it:
• Replace conditionals with parameterized test cases
• Use pytest.mark.parametrize for multiple scenarios
• Extract conditional logic into helper functions
• Use assertion libraries like assertpy for complex conditions
💡 Example:
# ❌ Instead of this:
def test_user_access():
user = create_user()
if user.is_admin:
assert user.can_access_admin()
else:
assert not user.can_access_admin()
# ✅ Do this:
@pytest.mark.parametrize('is_admin,can_access', [
(True, True),
(False, False)
])
def test_user_access(is_admin, can_access):
user = create_user(admin=is_admin)
assert user.can_access_admin() == can_access
🔍 File: test_user.py
📍 Function: test_user_access
```
## External Context Integration
The hook can integrate with external APIs to provide additional context and examples.
### Context7 Integration
Provides additional analysis and context for rule violations using advanced language models.
### Firecrawl Integration
Scrapes web resources for additional examples, best practices, and community solutions.
### Configuration
```bash
# Enable external context providers
export QUALITY_CONTEXT7_ENABLED=true
export QUALITY_CONTEXT7_API_KEY="your_context7_api_key"
export QUALITY_FIRECRAWL_ENABLED=true
export QUALITY_FIRECRAWL_API_KEY="your_firecrawl_api_key"
```

3. The hook will analyze and potentially block the operation
## Test Quality Checks
When enabled, the hook performs additional quality checks on test files using Sourcery rules specifically designed for test code:
### Test-Specific Rules
- **no-conditionals-in-tests**: Prevents conditional statements in test functions
- **no-loop-in-tests**: Prevents loops in test functions
- **raise-specific-error**: Ensures specific exceptions are raised instead of generic ones
- **dont-import-test-modules**: Prevents importing test modules in non-test code
### Configuration
Test quality checks are controlled by the `QUALITY_TEST_QUALITY_ENABLED` environment variable:
```bash
# Enable test quality checks (default)
export QUALITY_TEST_QUALITY_ENABLED=true
# Disable test quality checks
export QUALITY_TEST_QUALITY_ENABLED=false
```
### File Detection
Test files are automatically detected if they are located in directories containing:
- `test/` or `tests/` or `testing/`
Example test file paths:
- `tests/test_user.py`
- `src/tests/test_auth.py`
- `project/tests/integration/test_api.py`
