Non-functional testing is focused on evaluating aspects of a solution that relate to how it operates in real-world scenarios rather than its specific functionalities. This type of testing assesses attributes such as performance, scalability, security, and reliability, which are crucial for understanding how the application will behave under various conditions in an operational environment.

For instance, through non-functional testing, teams can identify potential bottlenecks in the system when subjected to heavy user loads or measure response times for critical operations. It provides insights into whether the solution can meet the performance expectations of users once deployed, ensuring that it is robust and efficient under operational conditions.

In contrast, functional testing primarily ensures that the features of the solution work as intended according to the requirements, while usability testing assesses how user-friendly and intuitive the application is for the end user. A/B testing explores variations of a solution to determine which performs better in specific conditions but does not provide a comprehensive view of the solution's performance in a live operational context.
