Functional Testing vs Usability Testing

 

Although the distinction between functional testing and usability testing may seem obvious to many testers, it actually confounds many professionals in our business. 

Both are essential components of the testing process, so you'd think we'd spend more time figuring out, talking about, and explaining their differences than we really do.

Sapizon Technologies is one of the leading Software Testing Company in USA with numerous of clients in our references. We are one among the top software test company where the work flow is perfect with possible outcomes.

Let's first examine the distinctions between the two steps and what each one specifically entails in order to correct this. 

Without taking design ideas into account, functional testing is done to make sure the product behaves as required for its intended use. 

This comprises a sequence of tests that validate behaviour, feature by feature, utilising a variety of accurate and inaccurate input data. 

Usability testing, in contrast, focuses on user acceptance and how well the user can use the product to fulfil the required activity. 

Usability testing looks into all facets of a product's usability, including overall structure, navigational flow, element placement on a page, content clarity, and general behaviour.

Usability testing should be conducted after functional testing, when any functional flaws have been corrected. Usability testing on products with functional flaws simply reveals functional issues, which frustrates users who are hampered by bugs while attempting to accomplish a task. The utility of the results is invalidated, the participants are hampered, and their impression (and thus their feedback) are badly impacted.

Functional and usability testing both need very distinct mentalities from the tester, who should preferably not be engaged in the product's creation. 

The attitude of "CAN I accomplish what I need to do; does this product work?" is necessary for functional testing. 

Given that the name "testing" inevitably conjures up images of functional testing first and foremost, usability testing is more about "usability" than it is about "testing" and requires the attitude of "HOW can I do what I need to do; does this make sense?"

Participants in usability testing conduct a number of crucial tasks that users of a product should be able to accomplish using the product. Participants are required to respond to a number of task-related questions when each activity is finished. Multiple-choice questions about task completion success or failure, task difficulty, and rating of any additional assertions that may be pertinent are all included in these questions. For instance, evaluating a page's completeness, utility, and relevance of information would fall under this report. The "think aloud/write down" technique is another way that participants are urged to express their ideas, suggestions, and worries. This information is crucial for understanding the "why" behind specific usability issues and the value you receive.

Although the two types of testing are similar, there are clear differences between them that are crucial to the testing process. Functional testing evaluates whether or not the product functions as it should, whereas usability testing examines whether or not the end user can access those functions and successfully use the product. This is a straightforward way to think of the difference between functional testing and usability testing.
