🔍 Code Extractor

A test function that validates configuration settings by importing and calling the Config.validate_config() method, printing the result and returning a boolean status.

Purpose

This function serves as a configuration validation test utility, typically used in testing or setup scripts to verify that the application's configuration is properly loaded and valid before proceeding with main operations. It provides user-friendly console output indicating success or failure of configuration validation.

Source Code

def test_configuration():
    """Test configuration loading."""
    print("Testing configuration...")
    try:
        from config import Config
        Config.validate_config()
        print("✓ Configuration is valid")
        return True
    except Exception as e:
        print(f"✗ Configuration error: {e}")
        return False

Return Value

Returns a boolean value: True if the configuration is successfully validated without exceptions, False if any exception occurs during the configuration import or validation process. The return type is implicitly bool, though not annotated in the function signature.

Dependencies

• config

Required Imports

from config import Config

Conditional/Optional Imports

These imports are only needed under specific conditions:

from config import Config

Usage Example

# Ensure config.py exists with Config class
# Example config.py:
# class Config:
#     @staticmethod
#     def validate_config():
#         # Validation logic here
#         pass

# Run the test
result = test_configuration()
if result:
    print("Configuration test passed, proceeding with application")
else:
    print("Configuration test failed, check your settings")
    sys.exit(1)

Best Practices

• This function should be called early in application startup or in test suites to catch configuration errors before main execution
• The function catches all exceptions broadly, which is appropriate for a test function but may hide specific configuration issues
• Consider logging the exception details to a file for debugging purposes in production environments
• The function performs a lazy import of Config inside the try block, which means import errors are also caught and reported
• Use this function in CI/CD pipelines or pre-deployment checks to validate configuration integrity
• The function prints to stdout, so it's best suited for CLI applications or test scripts rather than library code
