Functional Testing vs. Non-Functional Testing

Functional testing and non-functional testing are two key types of software testing that are essential for ensuring the quality and performance of a product. Here's a brief explanation of the differences between the two:

Functional Testing:

Functional testing focuses on testing the specific functions or features of the software application to ensure they work as expected. It involves testing the application against the functional requirements and specifications. The main goal of functional testing is to verify that the software meets the intended requirements and functions correctly.

Non-Functional Testing:

Non-functional testing, on the other hand, is focused on testing the non-functional aspects of the software, such as performance, reliability, scalability, and usability. It evaluates how well the software performs under various conditions and how user-friendly it is. Non-functional testing aims to assess the overall quality of the software beyond just its functionality.

Overall, while functional testing ensures that the software meets the functional requirements, non-functional testing evaluates its performance and quality under various non-functional aspects.
