The practice of writing tests for the smallest pieces of code in a system is known as ________ testing in CodeIgniter.
- Integration
- Regression
- System
- Unit
In CodeIgniter, writing tests for the smallest pieces of code is known as unit testing. It involves testing individual units or components in isolation to ensure they function as expected. This helps identify and fix bugs early in the development process, contributing to overall code reliability and maintainability.
To handle complex scenarios, CodeIgniter's database configuration supports the use of ________ to extend its capabilities.
- drivers
- extensions
- features
- plugins
To handle complex scenarios, CodeIgniter's database configuration supports the use of drivers to extend its capabilities. Drivers allow developers to use different types of databases or customize database functionality as needed.
For advanced dependency management in custom libraries, CodeIgniter developers often use the ________ pattern.
- Dependency Injection
- Factory Pattern
- Observer Pattern
- Singleton Pattern
In CodeIgniter, the Factory Pattern is commonly employed for advanced dependency management in custom libraries. It allows developers to create objects without specifying the exact class of the object that will be created. This promotes flexibility and easier maintenance.
How can you enable profiling in a CodeIgniter application?
- $config['enable_profiler'] = TRUE;
- $config['enable_profiler'] = FALSE;
- $this->config->set_item('enable_profiler', TRUE);
- $this->config->set_item('enable_profiler', FALSE);
In CodeIgniter, enabling profiling is done by setting the enable_profiler configuration option to TRUE. It provides a detailed report of the execution of your application, helping in performance analysis.
An application allows users to share their achievements directly to their social media accounts. This feature primarily utilizes the ________ of the social media platform's API.
- Authentication
- Webhooks
- Endpoints
- Authorization
The correct option is "Authorization." When sharing achievements on social media, the application needs to access the user's account without exposing credentials. Authorization ensures that the app has the necessary permissions to post on the user's behalf.
In CodeIgniter, how can you redirect the user to a different method within the same controller?
- $this->load->redirect('method_name')
- $this->load->set('location', 'method_name')
- $this->load->view('method_name')
- $this->redirect('method_name')
To redirect a user to a different method within the same controller in CodeIgniter, you can use $this->redirect('method_name'). This method simplifies the process of redirecting and improves code readability.
What is the primary purpose of pagination in a CodeIgniter application?
- Improving user experience with faster page loads
- Organizing data for better readability
- Simplifying code structure for better maintenance
- Splitting large datasets into smaller chunks
Pagination in CodeIgniter is primarily used to split large datasets into smaller, more manageable chunks. This enhances the user experience by enabling faster page loads and makes it easier to navigate through large sets of data.
In the Active Record Class, which method is typically used to insert a new record into the database?
- add()
- create()
- insert()
- save()
The insert() method in the Active Record Class of CodeIgniter is used to insert a new record into the database. It allows you to specify the table and the data to be inserted. This method simplifies the process of adding data to the database using an object-oriented approach.
The ________ feature in CodeIgniter's database utilities is used to improve query execution time.
- Lazy Loading
- Query Caching
- Query Optimization
- Result Compression
CodeIgniter's Query Caching feature is used to improve query execution time. By caching query results, subsequent requests for the same data can be served more quickly.
In a try-catch block, what is the role of the 'finally' clause?
- Declares a variable to store exception details
- Defines a custom exception message
- Executes code regardless of whether an exception is thrown or not
- Specifies the code to be executed if an exception is thrown
The 'finally' clause is used to specify a block of code that will be executed regardless of whether an exception is thrown or not. This is useful for tasks such as releasing resources or closing connections, ensuring cleanup operations are performed.
