The testing phase in the Software Development Life Cycle (SDLC) is specifically focused on debugging because this is when the software is evaluated to identify any defects or issues. During testing, various techniques are employed to rigorously examine the software, ensuring that it meets the specified requirements and functions correctly. Testers run different types of tests, such as unit tests, integration tests, system tests, and acceptance tests, all aimed at finding and fixing bugs before the software is released.

In contrast, the implementation phase is focused on deploying the software and ensuring it operates in the intended environment, while the analysis phase is concerned with gathering requirements and defining the project's scope. The maintenance phase occurs after deployment and involves updating and fixing issues that arise once the software is in use, but the initial identification and correction of bugs take place primarily during testing. Thus, the testing phase is crucial for ensuring that a program is functioning correctly and is free from major issues before it is released to users.
