Desktop Application Testing vs Web Application Testing

There are two basic types of software used to carry out operations on a computer system: desktop applications and web applications. Both have benefits and drawbacks, but there are many ways, including how they were developed, how they were used, and how accessible they were. 

What are Web applications? 

Web applications are software applications that run on a web server and can be accessed through a web browser.  

Applications known as web applications can be using a web browser and executed on a web server. They require an internet connection to function and are developed using web technologies such as HTML, CSS, and JavaScript. The major advantage of web applications is that they are accessible from anywhere with an internet connection and a web browser, regardless of the device or operating system. This means that users do not need to download or install anything to use a web application. 

Web Application Testing

Web application testing refers to the assessment of a software application accessed through a web browser to verify its functionality, usability, security, and performance. It involves conducting tests for browser compatibility, cross-platform adaptability, and evaluating security vulnerabilities and performance under varying user loads.

Web applications testing techniques  

  1. Functional testing, 
  2. Performance testing 
  3. Security testing 
  4. Usability testing 
  5. Compatibility testing 

What are Desktop applications? 

Desktop applications are software applications that run on a personal computer or laptop. 

Desktop applications, on the other hand, are programs that are installed and run locally on a computer system. They are developed using programming languages such as Java, C++, or C# and require an installation process to be used. Desktop applications can function without an internet connection, but they are limited to the device and operating system they were developed for. This means that if a user wants to access a desktop application on a different device or operating system, they need to download and install it again.

Desktop applications testing

Desktop application testing refers to the evaluation and verification of the functionality, usability, and performance of a software application installed and operated on a local computer. It involves ensuring compatibility with specific operating systems, validating the user interface, and verifying installation, configuration, and system resource utilization. The goal is to deliver a reliable and efficient desktop application that provides a seamless user experience.

Desktop applications testing techniques 

  1. GUI testing,  
  2. Compatibility testing 
  3. Installation testing 
  4. Functional testing 

Difference between testing desktop applications and web applications 

Desktop Application Testing 

Web Application Testing 



  • The desktop software is made to work with a certain operating system, such as Windows, Mac, or Linux. 


  • Desktop applications need to be tested on different operating systems to ensure that they are compatible and perform well. 



  • The advantage of desktop applications is that they can be more powerful and feature-rich than web applications. 


  • Desktop Applications can access the computer’s hardware resources, such as the CPU and GPU, to perform complex operations 


  • This makes them suitable for tasks that require high performance, such as video editing or gaming. 


  • Desktop applications are less vulnerable to security threats since they are installed on the user’s computer and do not rely on the internet for their functionality. 


  • Desktop applications still need to be tested for security vulnerabilities to ensure that they do not compromise the user’s computer or data. 



  • Web applications need to be tested across multiple browsers and devices 



  • The web application is essential to ensure that they are compatible with different browsers such as Google Chrome, Mozilla Firefox, and Safari 


  •  Web applications can be  using a web browser and executed on a web server. 


  • Developing desktop applications can be more complex and time-consuming than developing web applications. 


  • Web Applications require specific programming languages and development environments, and the developer 


  • applications are more susceptible to security threats such as hacking and phishing attacks 



  • web applications need to be tested for security vulnerabilities such as SQL injection, cross-site scripting, and cross-site request forgery. 

In conclusion, when it comes to desktop application testing and web application testing, QACraft recognizes the importance of tailoring the testing approach to the specific requirements of each application type. Desktop application testing focuses on operating system compatibility, user interface, and installation procedures, while web application testing emphasizes browser compatibility, cross-platform adaptability, and security/performance assessments.
