How does MVC architecture enhance unit testing of individual components?
- By eliminating the need for unit testing
- By making unit testing more complex
- By promoting separation of concerns
- By restricting access to components
MVC architecture enhances unit testing by promoting separation of concerns. Each component (model, view, controller) has a distinct role, making it easier to isolate and test individual units. This modular approach facilitates more effective unit testing, leading to improved code quality and maintainability.
The technique of _________ effectively limits SQL injection by stripping out SQL commands from user inputs.
- Code Obfuscation
- Data Encryption
- Input Sanitization
- Output Validation
Input Sanitization is a security technique that involves cleansing user inputs to remove potentially harmful content, such as SQL commands. This helps prevent SQL injection attacks by ensuring that only valid and safe data is processed.
In CodeIgniter, where are session data typically stored by default?
- Cookies
- Database
- Server-side files
- URL parameters
By default, CodeIgniter stores session data on the server-side in files. This provides a secure and efficient way to manage user sessions without exposing sensitive information in cookies or other less secure methods.
Which file in CodeIgniter is typically modified to include a third-party library?
- autoload.php
- config.php
- index.php
- routes.php
