What is the GUI?
It is an acronym that stands for Graphical User Interface. A graphical user interface is just a form of user-friendly interface that enables users to interact on electronic devices such as touch screen, pointing devices, stylus, mouse, keyboard or other pointing devices, by using visual indicators and audio indicator like the light signal, colour and sound, rather than text-based input devices, typed commands or graphical representation.
It is handy for controlling devices such as DVD players, microwave ovens, video game consoles and PDA’s. It enables interaction in a highly interactive manner.
Insights on GUI
In a nutshell, a graphical user interface is just a way to access software applications on the computer, and it helps a user to interact with these applications. Now, the question comes- how can you make your software more user friendly and make it easy for people to use?
There are various ways and tools available in the market that can help you create this high-end technology. It is not enough to make a friendly-looking GUI for your device, but you should take care of its usability and ease of use. The primary purpose of software testing is to ensure that a particular software package fulfils its function adequately so that you do not have to spend more time and money on technical support.
If you use a command-line interface, it will be a bit hard for the user to use it, so it is recommended to use a graphical user interface for that purpose. The graphical user interface can also render multiple commands and visual elements more transparent and better because it is easier to understand than the command-line interface.
It is also easier to debug and rectify errors in the graphical user interface program because there is no special syntax. A command-line interface will indeed be more powerful, but it will be challenging to learn and adapt to your business needs. If you think that using an old-fashioned GUI is not practical for your company, go for GUI testing.
Types of GUI
The types of GUI that a program uses depend on what it is to do. A command-line interface is one of these. Instead of with a programming language, a GUI built with a GUI engine is called a GUI driven application. The type of Graphical User Interface that a computer display depends on what it is to do.
Simple types of GUI are those that have been derived from a programming language. A simple graphical user interface is one that is capable of expressing an essential operation clearly and compactly. Examples of such a type are the file dialogue box, the Win mixer, and the character map dialogue box. Dedicated graphic user interface components can point out the following kinds of GUI:
Simple Graphic User Interface
It is probably the most common type of graphical user interface. It is also the oldest and therefore, the most familiar. It allows a program to communicate with a computer using only text commands. A classic example of this is the DOS-based interface. The data analysis screen reads characters as they are entered and accepts mouse-clicks for pointing at data. The arrow keys send the focus to another part of the screen.
It is a prevalent type of Graphical User Interface (GUI). A menu-driven interface allows a user to get more information by moving or clicking on the various areas. A typical menu-driven interface has four parts:
- The main window displays all the info bordered by a grey background.
- Sub-menus which shows further sub-menu information.
- Help menus that provide concise and detailed explanations of complicated menus.
- The DataBase, which stores all the data that is being used in the application.
It is possible to enter or save several data into the database. The Quit button brings the application to an end. There are many different kinds of menus, depending on the operating system and the graphing program. These are very similar to the menus found in graphical user interface examples. However, the distinction is that instead of displaying text, they say images. These could be graphics or text. The standard of this is MS PowerPoint.
Hybrid User Interfaces
These are entirely computer-based and require a user to drag and drop items onto the screen. Common examples of this are messenger applications, such as MSN Messenger, or Sun Java. The other difference is that these user interfaces may also contain components that are not visible to the users, for example, Java Swing components. They are either visually or physically implemented on top of the executable program. This type of interface allows developers to use programming languages like Java the same as DMA.
This kind of interface is quite similar to graphical user interfaces, except it allows the designer to scroll horizontally over the screen data. Common examples of this include dialers, telephone messaging systems, and web browsers. It is often associated with operating systems, such as the Windows operating system. A typical Scroll Component will tell the user how to scroll vertically or horizontally over the data. The Scroll Component also has a unique reserved keyword for use with the system.
Many web-based application programs today use a combination of these necessary user interfaces. It allows them to create an application that is interactive but also very convenient to use. The components used can be anything, including text boxes, labels, buttons, image controls, lists, and drop-down menus. The user’s interaction with the application is based on how effectively they learn the specific knowledge required. As more web-based application programs are created, the more appropriate types of interface will evolve.
Advantages of GUI
1. Most companies are familiar with the advantages of GUI design. However, when should a company consider implementing a GUI for their product? The Biggest Advantages of GUI testing are clarity and consistency. Consistency refers to the way that the application operates, and is the result of proper testing.
2. The most apparent Advantages of GUI testing are clarity. A company can achieve clarity and consistency with the use of GUI testing tools. An excellent example of a tool that can accomplish this is the GUI Test Runner. This software enables the end-user to see what they are getting into before they begin any transactions.
3. Another of the many advantages of GUI is its flexibility. Companies choose to implement a GUI system that allows for easy integration with legacy applications. It is also commonly known as an interaction model or a data model because it represents how information is there between applications. The GUI is the way that any given program interacts with its environment or other programs. The software designer must be aware of these disadvantages because they can prevent the successful implementation of a user interface.
4. The other advantages of GUI are that they allow for greater interaction levels, and more detailed information can be presented to the test users. Another advantage of using a GUI for interface design is that it is much faster to develop than a traditional application because there is no need to use the window manager. Because there is no need for the window manager to be open, the application can run in a simplified environment without many of the complications associated with a full-screen mode.
Disadvantages of GUI
Some of the disadvantages of GUI are related to the design of the desktop and the maintained data models. Typically the test user will not be able to visualize the contents of the data model. Most people who use a computer system do not know how to write a Graphical User Interface (GUI). It takes training to learn the necessary syntax for writing a Graphical User Interface in C. Luckily, most of the designers of GUI applications have had extensive training and have learned how to create user interfaces with ease. Due to this, there are two interfaces available to the designer.
The first is called Graphical User Interface Testing (GUIT). The second is the Graphical User Interface Testing (GUT) which is somewhat different because it focuses more on the application’s content and less on the graphic representation. Both of these methods include advantages and disadvantages. A suitable software program must choose which one will be best for the intended purpose and the test cases. The significant advantage of the GUIAT is that it allows for easier identification of bugs and mistakes in the design of the application because the testing is done with a specific set of criteria.
