Why, How & What is Usability Testing?

Usability Testing is a Black Box Testing Technique. Usability testing is done with users’ points of view. It is a technique implemented in user-centered interaction design to evaluate a product or service by testing it with representative users. On the Web page, the usability is the most important and required condition for survival.

If the website is difficult to use, then, peoples will not stay on the page. If the page content or details are hard to read or understand, then also peoples will leave the page. So Usability testing plays an important role which assesses how easy user interfaces are to use.

Usability testing is an essential element of quality assurance. It is the measure of a product’s potential to accomplish the goals of the user. Usability testing is a method by which users of a product are asked to perform certain tasks to measure the product’s ease-of-use, task time, and the user’s perception of the experience. This looks like a unique usability practice because it provides direct input on how real users use the system.

• Usability testing measures human-usable products to fulfill the user’s purpose. The items which take benefit from usability testing are websites or web applications, documents, computer interfaces, consumer products, and devices. Usability testing processes the usability of a particular object or group of objects, where common human-computer interaction studies try to formulate universal principles.
• Usability features like “Look and feel” cannot be measured at all times because they are subjective. In usability testing, mostly testers test the ease with the use of user interface. The tester can test user-friendly or non- friendly applications or the products too. Usability testing is a true test of how people use a website & determines that whether a user is feeling comfortable with other applications or Web sites according to different parameters like; the flow, browsing, and layout, speed, and content.

Limitations of usability testing

Planning and data-collecting process are time-consuming. It is always confusing that why usability problems come. Its small and simple size makes it unreliable for concluding subjective user preferences.

It’s hard to create a suitable context. You can’t test long-term experiences. Unplanned social connections cannot be replicated. People act in a different way when they know they’re being observed.
