What is the difference between functional testing and non-functional testing in manual testing?

The focus keyword here is "functional testing and non-functional testing in manual testing." In manual testing, functional testing is focused on verifying if the software functions according to specifications and requirements, ensuring that all functionalities work as intended. On the other hand, non-functional testing in manual testing involves evaluating aspects like performance, usability, reliability, and scalability of the software.

While functional testing checks what the system does, non-functional testing checks how well the system does it. Both types play crucial roles in ensuring the quality and efficiency of software applications.
