Why Compatibility Testing?

Ensuring software is compatible with various environments. Given the constant development of the software market, it is impossible to create new products/applications with only one particular platform/browser/OS in mind. If a website operates as expected on macOS, it does not mean there will be no defects when running in Windows.

Millions of users use different devices and browsers to interact with software. To avoid system issues under different conditions, QATestLab performs compatibility testing. Having the majority of popular devices at our disposal, we have already set up an environment with configuration tests to make sure that the solution operates as expected on all of them.

Why QATestLab?

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

Following business and functional requirements, we provide compatibility testing services to enable our customers to avoid financial risks and loss of reputation caused by poor system compatibility and negative user experience. Testing conducted before product release detects compatibility issues and prevents the budget overspend.

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:

  • Browsers - to verify whether the product is compatible with different browser versions and types, e.g., Chrome, Safari, Opera, Firefox, etc.
  • Operating systems - to check if the product operates as expected 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 as expected with different hardware configurations.
  • Networks - to evaluate the system operating in various connection types - Wi-Fi, 3G, 4G, etc.
  • Mobile operating systems - to ensure that solution is compatible with different mobile platforms - iOS, Android.
  • Mobile device models - to ensure that solution is compatible with different models of devices and manufacturers.

How we test

Based on requirements, business purposes, market specifics, and personal experience, we create a configuration matrix and select suitable methodologies. Our QA specialists assist in selecting types and versions of browsers, OS, platform, and hardware configurations for solution testing based on target user analysis - geography, age, lifestyle, preferences, etc.

Tools We Use

tools

To reduce the time required for testing, we evaluate, select and use particular tools to ensure effective compatibility assessment for the solution we are testing. Performing browser compatibility checking, we use BrowserStack to evaluate the system in various browsers. 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 the cost of checking OS compatibility. To provide effective mobile device compatibility testing, we try to avoid checking on emulations. We have a large selection of mobile devices and can perform testing on real smartphones and tablets.
