Usability testing primarily focuses on how users interact with a product in terms of user satisfaction, effectiveness, ease of learning, and overall user experience during regular use scenarios. The evaluation of user satisfaction encompasses how pleased users are with the product and whether it meets their needs. Effectiveness looks at whether users can successfully complete tasks using the product. Ease of learning assesses how quickly and intuitively users can pick up and use the product for the first time, indicating its accessibility for new users. Overall user experience involves capturing the holistic impression users have based on their interactions with the product, which includes emotional responses and personal evaluations.

On the other hand, while performance under stress conditions might be relevant for other types of testing, such as load testing or performance engineering, it is not a standard criterion for usability testing. This type of testing is more focused on normal use rather than extreme scenarios that assess system robustness or stability under pressure, making it an aspect that typically doesn't fall under usability testing evaluations.
