What is the significance of using mock objects in CodeIgniter unit testing?
- Mock objects are only used in front-end testing.
- Mock objects are used for creating visual elements in unit tests.
- Mock objects are used to execute real database queries.
- Mock objects help simulate the behavior of real objects, making it easier to test individual components in isolation.
In CodeIgniter unit testing, mock objects are essential for isolating the code being tested. They simulate the behavior of real objects, allowing developers to focus on testing specific components without the need for the entire application to be running. This isolation is crucial for identifying and fixing bugs in individual units of code, providing more reliable and effective testing.
