Compatibility Testing

Let’s assume that your application is a hit and has a good user base, but aren’t you worried about the churn out ratio?

Are the users who downloaded your app still using it?

When a mobile/web application is launched, it is imperative that it reflects the true value for the user. Compatibility testing helps to ensure complete customer satisfaction as it checks whether the application works consistently across multiple platforms & devices.

Why Compatibility Testing?

The main objective of compatibility testing is

  • To expand the user base and
  • To retain the existing user

Of course, there are a lot of responsive design technology for desktop/mobile are available in the market such as WordPress, Drupal, Joomla, Magento, Woocommerce, Prestashop, Sketch, Marvel, POP, UXPin,, Axure etc.

Some of the common compatibility issues which frustrate the user base are
  • Differences in the user Interface with respect to look and feel
  • Changes with respect to font size, alignment issues
  • Marked changes in CSS style and color, issues related to Scroll bar
  • Existence of broken tables or Frames
  • Content or label overlapping
  • Few other factors are the resolution of the images used, icons used, in-style customization, font size and position variation due to varying screen size, text over flow, link compatibility etc.

The list will always grow with the growing number of devices and versions.

Real Device and Real People for Testing

Compatibility testing has become a nightmare due to increasing number of devices and platforms that mobile apps and websites need to be cross-checked against. Thankfully, today we have a wide range of testing tools for the thorough testing process. But, how effective these tools are? These tools can be categorized into three broad categories: emulators, simulators, and real devices.

Which is the better option?

Emulators and Simulators are the cost-effective options when compared to real device testing. But, they have issues that may generate both false positive and negative results, which will surely have a negative impact on the business ROI. Another disadvantage of these tools is that howsoever close their feature may be to the real app, emulator/simulator may still not cover all features/scenarios and the results obtained may not be as accurate as on the real devices. With an efficient testing process, real devices can validate for every possible scenario with almost 100% accuracy.

Testing on Actual Device:

Nothing can beat testing on the actual device. Each device is unique and can manifest different problems including:





Emulators help identify the potential errors in a limited way and are not a reliable judge of the production-readiness of the game.

Your customers don’t use VMs or simulators to browser your website, or mobile app. So, don’t completely rely on these tools for test results.

Indium’s Compatibility Test Lab is also equipped with more than 350 devices from the most popular to the latest one in the market. Additionally, Indium has developed a tool agnostic framework for automated compatibility testing, iFACT (Indium Framework for Accelerated Compatibility Testing).

Our Compatibility Testing Success Story

Types of Compatibility Testing

  • Hardware Compatibility: Validating software compatibility for the different type of hardware system.
  • OS Compatibility: Validating is the software is compatible with different OSs such as MAC OS, Windows, Unix.
  • Software Compatibility: Validating if the developed software application is compatible with other module software.
  • Network Compatibility: Evaluation of performance of software/application in a network with varying parameters such as Bandwidth, Operating speed, Capacity.
  • Browser Compatibility: Compatibility check of the web application with different browsers like Firefox, Google Chrome, Safari, Internet Explorer etc.
  • Device Compatibility: It checks compatibility of your software with different devices such as mobile, tab, desktop etc.
  • Mobile OS Compatibility: Checking of the software/ application is compatible with mobile platforms like Android, iOS, Blackberry etc.
  • Versions Compatibility: It is verifying if the software application compatibility with different versions of OS.

    • The given application should be compatible with Windows 8, Windows 8.1, windows 10, Windows 10.1 etc.
    • There are two different types of version checks which are – Forward Compatibility Testing and Backward compatibility testing
    • In Forward Compatibility Testing, the software/ application is verified for its behavior with newer version of hardware/OS
    • In Backward Compatibility Testing, the case is just vice versa, the application is checked for the older versions of hardware/ OS.

Our offshore Compatibility Test Lab (iCTL) is a dedicated facility that enables our clients to leverage the end to end compatibility testing services to realize the benefits such as,

  • Faster time to market – flexible and shift operations to support up to 16 hours of test execution daily; Quick jump start execution phase – a repository of known failure patterns across various browsers and operating systems
  • On-demand capacity of QA
  • Start and stop time for accommodating the business cycle needs
  • Reduced Project Management overheads
  • Reduced Negative PR
  • Reduced tech support cost
  • Reduced bounced rate with improved user engagement thus helping in business success.
