Compatibility Testing

Why Compatibility Testing?

The number of operational systems, browsers, and hardware configurations is vast and a successful software solutions have to be compatible at least with the majority of them. QATestLab provides the services of compatibility testing to verify whether a solution works properly in different environments and, thus, obtains more users.

Following business and functional requirements, we provide services of compatibility testing so that our customers could avoid financial risks and loss of reputation caused by poor system compatibility and negative user experience. Testing conducted before the product release detects compatibility issues and prevents the pushing of the project budget over the prescribed limits.

Types of compatibility testing we do

QATestLab performs several types of compatibility testing to ensure that solutions for various industries operate flawlessly under different conditions. In terms of compatibility, we evaluate backward compatibility - capacity to operate with previous versions of the software - and forward compatibility - capacity to operate with future versions of the software.

We test software solutions to verify whether they are compatible with:

  • Browser - to verify whether the product is compatible with different browser versions and types, e.g., Chrome, Safari, Opera, Firefox, etc.
  • Operating system - to check if the product operates properly on various OSs: Windows, Linux, Mac, etc.
  • Software - to ensure that developed software is compatible with other software.
  • Hardware - to test if a solution works properly within different hardware configurations.
  • Networks - to evaluate the system operating in various connection types - WiFi, 3G, 4G, 5G, etc.
  • Mobile devices - to ensure that solution is compatible with different mobile platforms - iOS, Android, Windows.
  • Database - to evaluate the system capacity to work with different databases.

How we test

Based on requirements, business purposes, market specifics, and personal experience, we form a configuration matrix and select the suitable methodologies to define common configuration combinations and evaluate system compatibility under different conditions. Besides, our QA specialists assist in selecting types and versions of browsers, OS, platform, and hardware configurations for solution testing on the ground of the target user analysis - geography, age, lifestyle, preferences, etc.

Tools We Use

In order to reduce the time required for testing, we evaluate, select and use particular tools that ensure effective compatibility assessment for the solution we test. Performing browser compatibility checking, we use BrowserStack to evaluate system in various browsers. Besides, for users who prefer Internet Explorer, we use IETester to check solutions in IE versions 10 through 11. We use Chrome DevTools and Firefox Developer Tools to verify a solution against different resolutions. Testing on virtual machines, e.g., VMware and VirtualBox, reduces money expenses required for checking OS compatibility. To provide effective mobile device compatibility testing, we try to avoid checking on emulations. Having a large park of mobile devices, we perform testing on real smartphones and tablets.

In terms of the constant development of the software market, it is impossible to create new products / applications with only one particular platform / browser / OS in mind. Millions of users utilize different devices and browsers to interact with various software. If a website operates properly in one browser, e.g. Chrome, this does not mean that users will face no issues opening it in another browser, for example, FireFox.

The diversity of platforms, browsers, software and hardware configurations makes developers and testers take correspondent measures to provide flawless processes. The QA team performs configuration testing to avoid system issues under different conditions. Configuration tests require much means, e.g., mobile devices, OSs, and knowledge and skills of working with all of them.

Being focused on software testing, we possess the majority of popular devices, having already set up environment ready for testing and skilled specialists. QATestLab performs configuration testing to make sure that solution operates properly in various environments.
