Difference between GUI Testing and Usability Testing

1. GUI Testing :

It is the technique for making sure the appropriate performance of the graphical user interfaces for a precise application. GUI testing typically evaluates a sketch of elements such as layout, hues, and additionally fonts, font sizes, labels, textual content boxes, textual content formatting, captions, buttons, lists, icons, hyperlinks, and content.

Features of GUI Testing:

• Focuses on the visual interface: GUI testing is focused on testing the visual interface of software applications, including windows, buttons, menus, and other graphical elements.
• Ensures functionality: GUI testing ensures that the software application functions correctly and as expected, in terms of navigation, input fields, and other GUI features.
• Covers different platforms: GUI testing can cover different platforms and devices, such as desktops, laptops, mobile phones, and tablets.
• Automated or manual: GUI testing can be performed manually or through automated test scripts, depending on the complexity of the software application.
• Test cases: GUI testing includes the creation of test cases that verify the correct functioning of the graphical interface.

2. Usability Testing :

It is the exercise of checking out how effortless a plan is to use on a group of representative users. It generally includes looking at customers as they strive to complete duties and can be performed for unique sorts of designs, from user interfaces to bodily products. 

Features of Usability Testing:

• Focuses on user experience: Usability testing focuses on evaluating the user experience of the software application, including ease of use, navigation, and overall user satisfaction.
• Human-centric: Usability testing is performed with actual users to collect feedback and improve the software application’s user interface.
• Identifies pain points: Usability testing identifies pain points and areas of improvement that can be addressed to enhance the software application’s user experience.
• Evaluates user behavior: Usability testing evaluates user behavior and interactions with the software application, such as the time spent on a task, the number of errors made, and the overall user satisfaction.
• Test scenarios: Usability testing includes the creation of test scenarios that mimic real-world user interactions with the software application.

Similarities between GUI Testing and Usability Testing:

• Both GUI testing and usability testing focus on the software application’s user interface and the user experience.
• Both types of testing are important for ensuring the quality and reliability of software applications.
• Both types of testing can be performed manually or through automated test scripts.
• Both types of testing involve the creation of test cases or scenarios to verify the software application’s performance and user experience.
• Both types of testing require a collaborative effort between developers, testers, and users to ensure that the software application meets user expectations and requirements.

Difference between GUI Testing and Usability Testing are as follows: 

GUI Testing	Usability Testing
It is used to test the front-end part of any application.	It measures the extent of the friendliness of the User Interface part and overall functioning of the software.
It focuses on the look and feel of an application.	It focuses on the friendliness of an application.
It assures the look and feel of an application by matching with standards and user requirements.	It assures that the user should be comfortable to use any app by making its design easy.
In this, an application should be amazing in look whether it is easy to use or not.	In this, an application should be easy to use whether its appearance is up to the mark or not.
The testing is performed on various platforms just to make sure its appearance will be perfect.	It tests the app to check its difficulty level.
In this type of testing, we do not test the functionality of an app.	In this type of testing, we test the functionality of an app to check that is it user friendly or not.
It concerns the interface part of the software.	It focuses on the product quality of software.

Conclusion: Wuser-friendlyile both GUI testing and usability testing involve evaluating the user interface of a software application, they have different focuses, testers, methods, and metrics. Both types of testing are important for ensuring that software applications are functional and user-friendly, and they are often used together to provide a comprehensive evaluation of the application’s user interface.
