Compatibility testing explained

Compatibility testing is a test type of software testing that tests how well (or poorly) a software works on different devices, platforms, environments, browsers, etc. Compatibility testing tests the compatibility of your software with different hardware, software, and network and their different configurations.

Compatibility testing

• You test the compatibility of your online gaming website by testing its functionality and performance on different browsers, such as Chrome, Firefox, Safari, etc. You measure the rendering time, graphics quality, audio quality, and user interface of the website on different browsers.
• You test the compatibility of your mobile app by testing its compatibility with different operating systems, such as Android, and iOS. You measure the install time, memory usage, and battery consumption of the app on different operating systems.
• You test the compatibility of your database system by testing its compatibility with different data formats, such as JSON, XML, and CSV. You measure the percentages of input data validation, data conversion, and data integrity of the system on using different data formats.
• You test the compatibility of your video editing software by testing its compatibility with different video formats, such as MP4, AVI, MOV, etc. You test the video import, export, and editing features and note the error rates of the software on using different video formats.

Tips for compatibility testing

• Identify the compatibility requirements and technical specifications of your software system or application.
• Design the compatibility test cases that cover the most frequently used platforms for your software.
• Use compatibility testing tools like BrowserStack, Sauce Labs, and techniques to set up, execute and automate these test cases.
• Analyze and report the compatibility test results and report any compatibility defects or recommendations.

FAQ (interview questions and answers)

1. What is the difference between compatibility testing and cross-browser testing?
   Compatibility testing is a broad term that covers all types of testing that evaluate the compatibility of a software with different devices, platforms, environments, browsers, etc. Cross-browser testing is a specific type of compatibility testing that tests how well a website or web application works on different browsers.
2. What are some tools for compatibility testing?
   BrowserStack, Sauce Labs, TestComplete, etc.
3. Is compatibility testing a type of non-functional testing?
   Yes, compatibility testing is a type of non-functional testing that tests how well a software works on different platforms.
4. How do you perform forward and backward compatibility testing?
   Forward compatibility testing by test how well a software system or application works with newer versions of devices, platforms, environments, browsers, etc. and backward compatibility testing by test how well the software with older versions of devices, platforms, environments, browsers, etc.
