The statement is true because testing each internet application layer independently enhances the ability to pinpoint bugs and errors in the system. This approach, known as layer-specific or unit testing, allows for isolation of each layer's functionality. By examining each layer—such as the presentation layer, application layer, and data layer—independently, testers can verify that each segment of the application performs its intended function without interference from other layers.

This isolation means that when a bug is detected, it can be attributed to a specific layer, making it easier to identify the root cause. Additionally, it allows for more comprehensive test cases to be developed for each layer, facilitating more thorough validation of functionality and performance. In essence, independent testing leads to clearer insights into where failures occur and fosters a more efficient debugging process, ultimately contributing to greater software quality overall.
