Desktop Applications Testing

Desktop applications are stable solutions that can be easily sold and distributed as well as being complex systems used to ensure stable access to different database types. By performing desktop application testing, QATestLab makes sure that the solution works well and is stable enough to fully satisfy users’ needs.

We verify different aspects of a product to improve its quality by detecting weak points connected with its functionality, usability, security, maintainability, acceptability and compatibility.

In comparison to web products, desktop applications are usually more user-friendly and enable the user to customize the interface. They are more responsive and their performance speed is greater.

In order to make sure that desktop applications work as expected without any issues or defects, we write and execute the test cases for verifying different aspects of desktop software products.

How We Test

desktop application testing

To provide complete testing of desktop applications and cover all aspects of the software, we conduct a range of different types of testing.

Also, we check system functionality with multiple user accounts paying special attention to distribution rights. By testing desktop solutions on various OSs, types, and versions, we make sure that all users will be able to install, run and use the product properly. Moreover, we verify theme and layout changes on different screen resolutions. 

We aim to detect and facilitate complete removal of issues that may cause a negative user experience and reduce the company’s profit.

The most frequent bugs we find are:

  • Additional features/software installed together with user’s permission
  • Incorrect shortcut icon and its operation
  • Incorrect application uninstall process
  • Incompatibility with certain OS types
  • Memory leakage
  • Inappropriate error messages
  • Authorization and security issues
  • Errors with in-app functionality, and UI

Time Saving Assessment


Having tested many desktop applications, we have the majority of OS types already installed and ready for testing. This saves the time required for quality assessment and reduces cost. Also, we are able to ensure wide test coverage for compatibility testing.

We possess machines with minimum and maximum configurations to be able to detect hardware issues fast and effectively. By checking application interoperability, we aim to discover potential conflicts between the system and third-party software.
