What are Desktop Applications? and how to test desktop application (Software Testing Interview Question #17)

 What are Desktop Applications?

• The applications that can be installed on computer/laptops having Operating System using exe or dmg or deb files etc. are called Desktop Applications

• Some Desktop Applications are available by default too. For example paint etc.

• These are also known as Standalone Applications

• For the Windows operating system, desktop applications have the file extension .exe

• For the Mac operating system, desktop applications have the file extension .dmg

• For the Linux operating system, desktop applications have the file extension .deb

• Some Desktop Applications are available by default too.

Examples:

• Browsers like chrome, edge, etc.
• Paint etc.

How to test Desktop application :

• Installation Testing: We have to verify whether we are able to install it properly or not.

• Un-installation Testing: We have to verify whether we are able to uninstall it properly or not

• Functional Testing Whether able to use the functionality of the application  or not

• Compatibility Testing

- Testing on different supported Test Environments is a challenge

- Different Operating Systems, Versions, Configurations, Pre-requisite Software etc. 

- Virtual Environments helps a lot, as we have to do frequent installations and uninstallations

• Performance of the Application matters : How much resources - RAM, CPU and Disk Space etc. the Application is consuming matters

• Automation Testing : Selenium cannot automate Desktop Applications, we have to use Automation Tools like UFT, TestComplete, Winnium etc. (UFT, and testComplete are paid and Winnium is open source)
• 
  

• Security Testing: Check for vulnerabilities, data protection measures, and user access controls to ensure the application is secure from potential threats.

• Other types of Testing also will be performed but the above testing must be performed for testing the desktop application
