How compatibility check works

Before starting compatibility check, the expected environment or platform set for the application to run should be defined. A testing plan should be developed to identify the most important issues faced by the application, so that these tests can be prioritized, and less important tests can be set aside.

According to the products used for testing, it is necessary to set up environments that simulate the end user experience (such as desktops, smartphones, laptops, and tablets) to ensure that the test results are similar to what the user will encounter. It is important for testers to have a sufficient understanding of the various software, hardware, and platforms being tested to understand the expected behavior of various configurations.

Once the appropriate environment is set up, various types of tests can be run. All discovered errors should be reported in order to fix the defects. Then a retest should be run to ensure that all defects have been successfully resolved.

Possible testing defects

Some defects that may be discovered during compatibility check include:

size of font changing

Changes in user interface (UI), such as appearance and feel

Changes in CSS (cascading style sheets) style and color

Problem with scrollbars

Content alignment issues

Overlapping content or labels

Damaged frame or table

The importance of compatibility check

compatibility check is important as they confirm the successful performance of software applications on all platforms, ensuring that every customer can experience a positive experience regardless of the environment they use.

Due to inconsistencies in software versions, network speeds, configurations, and resolutions, defects can greatly hinder the end user experience. Therefore, it is necessary to evaluate applications in all possible ways to reduce the risk of any failure and the potential embarrassment of leaking applications with errors.

PC compatibility check Suite

Various tools have been developed to simplify the compatibility check process. Virtual desktops allow testers to run applications in the form of virtual machines (VMs) across various operating systems, thereby assisting in operating system compatibility check. Multiple systems can be connected and compared to produce the best results.

A large number of Cross-browser compatibility tools have also been developed. These include:
