●     Compliance and Standards

Software products must adhere to specific standards or compliance requirements in many different businesses. For instance, web applications might have to abide by compatibility specifications imposed by regulatory organizations or web accessibility standards like WCAG. Compatibility testing guarantees that software items adhere to these guidelines and rules.

●     Bug Identification and Resolution

Compatibility testing often identifies bugs or additional issues that conventional functional testing might miss. There may be behavioral differences between platforms and devices, which can result in specific bugs or performance snags. Developers can find and fix these problems through comprehensive compatibility testing before end users are impacted.

●     Optimizing Performance

Compatibility testing helps improve software product’s performance on various operating systems. By identifying potential areas of suboptimal performance on particular devices or browsers, developers can make necessary adjustments to improve overall responsiveness and performance.

Challenges

For both developers and testers, navigating the waters of Internet Explorer compatibility testing may be tricky. Now let’s look into the difficulties in testing for compatibility with Internet Explorer:

Dealing with Legacy Code and Outdated Features:

Dealing with legacy code and out-of-date features is a significant difficulty when testing for compatibility with Internet Explorer. The technologies and coding techniques used in developing many outdated web apps are no longer supported or compatible with contemporary browsers, including Internet Explorer. This old code can depend on out-of-date CSS, obsolete APIs, or plugins like ActiveX controls.

Managing ActiveX Controls:

The past support of ActiveX controls by Internet Explorer presented security and technical issues; for particular functions like multimedia playback, document viewing, or interactive features, many older web programs rely on ActiveX components. However, because of security flaws, modern browsers—including updated versions of Internet Explorer—have reduced or discontinued support for ActiveX. It might be challenging to test and ensure compatibility without using ActiveX controls; this frequently calls for alternate strategies or migration strategies.

Handling Compatibility Modes:

Compatibility modes in Internet Explorer allow web pages to appear as they would have in previous browser versions. Compatibility modes, especially concerning new web standards and responsive design, might aid in keeping outdated apps functional, but they can also cause rendering problems and inconsistencies. These challenges can be addressed by ensuring compatibility modes are handled correctly during testing and persuading users to use the most recent browser versions.

Testing Multiple IE Versions:

When evaluating Internet Explorer compatibility, it’s common practice to test many versions—including prior versions for particular legacy scenarios, such as Internet Explorer 8 or 9. The testing process becomes more complex when handling test settings with various IE versions, ensuring behavior and functionality are consistent across all targeted versions, and resolving version-specific issues or abnormalities.

Supporting New Web Technologies:

Developers need help with Internet Explorer, which only supports some of the latest web standards and technologies, like HTML5, CSS3, and current JavaScript APIs. To use contemporary web technologies’ capabilities and retain compatibility, it is imperative to implement fallbacks, polyfills, or alternative solutions for features not supported by previous versions of IE.

Compatibility Testing Methods

Compatibility testing can be carried out in several ways to ensure that the websites, apps, and software work perfectly on a gamut of hardware, operating systems, and browsers.
