In the last topic, we learned about Regression Testing. In this topic, we will learn about Usability Testing. Now,we will see about Usability Testing, It’s example and Usability Testing advantages and disadvantages. And where it will be used. Usability Testing is also one non-functional testing technique. In this we will measure how easily the user is able to understand the system. Means whichever product we have made, is he able to understand it and is he able to interact with the particular product or not? GUI has been designed properly or not. This is what we will keep in mind in Usability Testing. okay ? In short, what is Usability Testing? How easy is it to learn our product? Is it user friendly or not? Is it attracting the user or not? Come let’s take a very easy example. I want to print a transactional report. So, what are its steps? I logged in on the website and clicked on the Report section. Transaction list whichever I have to print, I selected that. Then I inserted the parameter like date, when I purchased the product, number of units, then I clicked on generate report, then I clicked on print report. Then I got the option of PDF, so I selected that. Oh my God! I am tired. It could have been simple. I logged in, went into my transaction and it was mentioned there Print Recent Transaction. It would be easy. Right? Here your work was done in 3 steps. In the previous one, how many steps it took. So, this is the flow of Usability Testing. There is an idea. How easily we can make our product, so that the user gets whatever output he wants in the minimum possible time. Now, we will talk about advantages and disadvantages of Usability Testing. 1st of all we will see advantages. What are the advantages? We will get direct feedback from the target audience. We will get direct feedback from our audience on how this particular application is working. How is its user interaction? From the internal discussion, we will also get to know which option is best to use. There will be a discussion and in it there will be 3 to 4 reviews which will tell us this option is better and this workflow is better. So, we will implement the decision well. Before launching the product any issue or any problem is there then it gets highlighted in Usability Testing. Now, we will talk about disadvantages. 1st of all, the testing is not possible like in a 100% real life scenario. You will think, why? See how it is there in it. In the company’s WIFI I did testing on a mobile application but the company’s WIFI is on a high speed. So, my application worked. The same application I tested on 2G or I am using it on 2G. Application is not responding. Sometimes it crashes. So, you can understand what is the disadvantage of this particular testing. After that comes in, we take feedback of small samples and we consider that for Usability Testing. Because Usability Testing is qualitative. Therefore, we give this application to 4 to 5 people to test to see what is its output, how is user interaction with it. Right? And its 3rd disadvantage is that if we want to make a real-life usage of it, so for the environment setting the things that we want, it’s cost might go high. So, this is also a disadvantage of Usability Testing. Usability Testing, where to use? In the Iterative design process, through usability testing, we will test that if the product is developing as per its usability or not? So, we learned about Usability Testing. Example and advantages and disadvantages of Usability Testing. And where it will be used. In the next topic, we will see the types of Non-Functional Testing.
