In this section, we will learn about usability testing, why we need it while testing an application, component of usability testing, etc.
Following are the topics, which we will understand in this section:
What is usability testing?
This is also an essential part of non-functional testing.
Checking the user-friendliness, efficiency, and accuracy of the application is known as Usability Testing."
It is a wide testing where we need to have an application knowledge.
When we use usability testing, it makes sure that the developed software is easy while using the system without facing any problem and makes end-user life easier.
Usability testing is testing, which checks the defect in the end-user interaction of software or the product.
It is also known as User Experience (UX) Testing.
Usability testing can be done at the design stage of the Software development life cycle (SDLC), and that helps us to get more clarity of the user's needs.
Here, the user-friendliness can be described in many aspects, such as:
Easy to understand
Easy to Access
Easy to Access
Faster to Access
Effective navigation is the most important aspect of the software.
Some of the following aspects for effective navigation:
Good Error Handling
Examples of usability testing
Let us see some examples, where we understand the use of usability testing.
We are taking one banking application where we produce the application for the manager.
Note: Here, the manager is the end-user.
Now, if the end-user (manager) starts using the application in front of the test engineers
Suppose two test engineer sits at the back of the end-user while he/she is using the application and takes the report of the defect as a developer to check whether the end-user is using the application in a right way or not.
And the end-user (manager) will check the application step by step because he/she knows that the Test engineer is watching him/her.
Note: Generally, the professional test engineers do not perform usability testing because they know where exactly the particular feature will fail and how it works.
|Efficiency||The end-user who is an expert takes the minimum amount of time to perform his/her basic task.|
|Memorability||The memorability of an application is good, When we are not asking an application for a span of time, and return to the application or trying to do the basic task without any help.
Or If we are not able to perform a basic task without any help after a duration of the time period, then we can say that the memorability of an application is not good.
|Learnability||The end-user takes a minimum amount of time to learn the basic task.|
|Satisfaction||The Customer must be satisfied with the application and feel free to use the application.|
|Errors||Here, we try to help the end-users to resolve those errors which they made earlier and perform their tasks again.|
The usability testing checklist contains all the documents which are related to usability testing.
To make the usability testing successful, we will prepare the checklist, which means that "what are the points to check". Or if we do not make a checklist, we may miss some features in the application.
Let see one example where we are creating a checklist for an application:
If we take the one E-commerce application and prepare the checklist, it would be like as below:
Like this, we can drive as many checklists as possible based on the product or the application.
When we test the application or the software with the help of usability testing, we may encounter some bugs. These bugs could be the Path holes and Potential bugs.
Path holes & potential bugs
Path holes and potential bugs are those, which are visible to the developers and the test engineers while performing usability testing.
The advantages of usability testing are as follows:
