Which testing type would evaluate the control a user has over software operations?

Operability testing focuses specifically on how well users can utilize and control the software operations. It examines the ease with which users can perform their intended tasks and assess how effectively they can interact with the system’s functionalities. This type of testing aims to identify potential issues that could hinder the user experience and addresses the overall user control and management of the application. It ensures that the software is not only functional but also intuitive, allowing users to efficiently execute tasks within the software.

Usability testing, while also concerned with the user's experience, primarily targets the overall user satisfaction and the ease of use rather than specifically evaluating control over operations. Functional testing is aimed at verifying that the software behaves according to specified requirements, focusing on whether the software performs its functions correctly. Performance testing assesses the speed, responsiveness, and overall stability of the software under various conditions but does not delve into user control over software operations.
