Software Testing And Quality Assurance Questions
Functional testing is focused on testing the functionality of a software application or system. It involves verifying that the software meets the specified functional requirements and performs the intended tasks correctly. This type of testing checks if the software functions as expected and if it produces the desired outputs.
On the other hand, non-functional testing is concerned with testing the non-functional aspects of a software application or system. It involves evaluating the performance, reliability, usability, security, and other non-functional characteristics of the software. Non-functional testing aims to assess the overall quality of the software and ensure that it meets the user's expectations in terms of speed, scalability, user experience, and security.
In summary, the main difference between functional and non-functional testing lies in their focus. Functional testing verifies the functionality of the software, while non-functional testing evaluates its non-functional aspects such as performance, usability, and security.
