suresh In a software development process, functional testing and non-functional testing are crucial aspects that ensure the quality and functionality of the software being developed. Here is a succinct breakdown of the differences between functional testing and non-functional testing:
Functional Testing:
Functional testing is focused on verifying that the software application performs the functions it is intended to perform. It tests the application against the functional requirements specified by the business or client.
The main goal of functional testing is to ensure that the software meets the end user's needs and expectations.
Examples of functional testing include unit testing, integration testing, system testing, and user acceptance testing.
Non-Functional Testing:
Non-functional testing, on the other hand, is focused on testing the attributes of the software application that are not related to its specific functions. It tests the performance, reliability, usability, and scalability of the software.
The main goal of non-functional testing is to evaluate the software's performance under specific conditions such as load, stress, and security.
Examples of non-functional testing include performance testing, load testing, stress testing, security testing, and usability testing.
In conclusion, while functional testing ensures that the software functions correctly as per the requirements, non-functional testing evaluates the quality attributes of the software beyond its basic functionality. Both types of testing are essential in ensuring the overall quality and reliability of a software application.
