Hello friends! In this post, we will be learning about – Usability testing. We will check its attributes, advantages, and some of the popular usability testing tools.

As the name suggests, it is a type of testing that deals with measuring the usability of the application. It is very critical to the application’s success. As it measures the ease with which a user can accomplish a task. Which in turn directly relates to the revenue and other business goals.

Usability Testing Definition

Usability testing is a type of non-functional testing that determines the degree to which an application can be easily used and operated. It can be performed by the internal team or a small set of end-users. These users explore the different functionalities of the application and share the usability defects.

Attributes of Usability Testing

  1. Ease of use – To check how easily a user can use the different functionalities of the application.

  2. Ease of learning – To check how easily users can learn to use the application.

  3. Memorability – To check how easily the user can remember the different flows of the application after exploring it for the first time.

  4. Error rate – While using the application, how often do users make mistakes and how easily can they recover from those errors?

  5. Level of satisfaction – This a subjective attribute that deals with the satisfaction or the general opinion user has about the product.

Advantages of Usability Testing

  1. In Usability testing, the development team gets direct feedback from the potential user. This helps in creating a product that meets the user’s expectations.

  2. Increased user satisfaction with the product leads to a meeting of business goals.

  3. Issues are identified before the actual release of the product, this maximizes the chances of the product’s success.

  4. Well-conducted usability testing helps in minimizing the overall project cost. This is because usability bugs found after the actual release lead to a higher cost of bug fixing.
