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.
Which feature in CodeIgniter can be used to improve performance by caching entire web pages?
- Database Caching
- Fragment Caching
- Object Caching
- Page Caching
CodeIgniter provides a feature called 'Page Caching' to store entire web pages in the cache. This helps in improving performance by serving pre-rendered pages instead of re-rendering them on every request.
When developing a mobile app with in-app purchases, the payment gateway integration should prioritize ________ for enhanced user experience.
- Blockchain Technology
- CAPTCHA Authentication
- Seamless Checkout Process
- Two-Step Verification
Prioritizing a seamless checkout process in the payment gateway integration for in-app purchases enhances the user experience, reducing friction and increasing the likelihood of successful transactions.
What is the role of CAPTCHA in form validation?
- Encrypts data transmission
- Ensures the form is submitted by a human
- Validates email addresses
- Verifies server connection
CAPTCHA (Completely Automated Public Turing test to tell Computers and Humans Apart) plays a crucial role in form validation by ensuring that the form is submitted by a human and not an automated script or bot. This helps prevent spam submissions and enhances security.
To use a third-party library in CodeIgniter, you must first __________ it in the application's configuration.
- Configure
- Initialize
- Integrate
- Load
In CodeIgniter, to use a third-party library, you need to configure it in the application's configuration. This involves specifying the necessary settings and parameters to make the library work seamlessly with your CodeIgniter application.
Which CodeIgniter library is primarily used for handling sessions?
- Cookie Library
- Data Library
- Database Library
- Session Library
The Session Library in CodeIgniter is specifically designed for handling sessions. It provides functions to set, retrieve, and manage session data effectively. Integrating this library is a common practice for session management in CodeIgniter applications.
During the migration of a CodeIgniter application from development to production, it is crucial to modify the ________ settings to ensure proper functioning.
- Caching Configuration
- Database Connection
- Error Logging
- Session Configuration
When migrating a CodeIgniter application, adjusting the database connection settings is essential to ensure that the application connects to the correct database in the production environment. This involves updating the database hostname, username, password, and database name in the database.php configuration file.
What file extension is typically used for controller files in CodeIgniter?
- .ci
- .php
- .ctl
- .controller
In CodeIgniter, controller files typically have the ".php" file extension. This is a common convention for PHP files. The ".ci" and other options are not standard file extensions for CodeIgniter controllers.
What is the primary function of CodeIgniter's Cross-Site Request Forgery (CSRF) protection?
- Ensuring secure password storage
- Mitigating cross-site request forgery
- Preventing unauthorized data submission
- Protecting against cross-site scripting
CodeIgniter's CSRF protection aims to prevent unauthorized data submission by generating and validating unique tokens for each request.
Describe the role of seeding in automated testing scenarios.
- Test Data Generation
- Code Optimization
- Performance Testing
- Automated Deployment
Seeding in CodeIgniter involves generating test data for automated testing scenarios. The "Test Data Generation" option accurately reflects the role of seeding in providing consistent and reproducible data for testing purposes.
