While executing software testing, it is very important for the testers to ensure the app’s compatibility across multiple web browsers and devices. Although Internet Explorer is witnessing declining usage, it remains a challenge for the developers to implement proper functioning on this browser. However, with the integration of Internet Explorer online, testers can solve this issue.

With this article, we will understand the advanced compatibility testing approaches for Internet Explorer online. We will also understand how these approaches allow testers to create websites seamlessly across all Internet Explorer and other browsers.

The Current Market of Internet Explorer

Many years ago, Internet Explorer was the dominant web browser as it was the only way of accessing the Internet. However, for quite a while now, it has been on a steady decline in usage. It is still in use, mostly in enterprise environments where legacy apps and systems rely on it.

Therefore, ignoring Internet Explorer compatibility can result in significant user experience issues for a huge segment of end users. Moreover, due to these issues, companies and brands can lose their audience base.

Challenges of Internet Explorer Compatibility Testing

While testing modern websites for Internet Explorer compatibility, the testers will encounter various challenges and obstacles. To shed more light on this segment, we have mentioned some of the most notable challenges below:

• Multiple Versions

Internet Explorer has various versions they are available in the present software market. Each version is significantly different in terms of rendering and JavaScript support. So, it becomes a hectic and challenging process for the developers to test their web apps across all versions.

• Non-Standard Behavior

Internet Explorer has historically implemented certain CSS and JavaScript features in a different format. This format often does not align with the standard web development features or practices that are followed in the present industry. Therefore, it becomes challenging for the developers to adjust the software testing parameters accordingly.

• Lack of Developer Tools

Unlike Mozilla Firefox or Google Chrome, Internet Explorer’s older versions do not have modern developer tools. Therefore, the developers will find it challenging to implement proper debugging steps to find critical errors within the app infrastructure.

Basic Compatibility Testing

Before diving into the advanced approaches of implementing compatibility testing on Internet Explorer online, let us go through some of the basic browser compatibility steps that the developers can implement to sort out the initial issues:

• Manual Testing
  
  The testers can manually launch the website in different versions of Internet Explorer to execute the test cases. During this process, they have to identify visual and functioning issues that might be present in the app development process. However, we would like to warn the developers that manual testing is not only a time consuming process, but it is also prone to errors due to human involvement.

• Virtual Machines

Using virtual machines, the testers can use multiple simulators and emulators to replicate various versions of Internet Explorer. With this option, the testers do not have to install every version of Internet Explorer on their physical devices. However, it is worth remembering that virtual machines cannot replicate the physical parameters of a device and will return flaky test results in these instances.

• Online Services

There are various platforms easily available in the market that provide cloud-based testing environments where the testers can test their website on various browsers and platforms. These browser options also include various versions of Internet Explorer for executing comprehensive test cases.

Advanced Compatibility Testing Techniques

To resolve the challenges of Internet Explorer compatibility in a more comprehensive manner, the application testers have to implement advanced testing approaches as and when required. To further elevate the knowledge of modern testers in this segment, we have mentioned some of the most important techniques below:

1. Automated Regression Testing

Automation testing is one of the most important components for efficiently testing the browser’s compatibility across multiple versions of Internet Explorer. For this purpose, the testers can utilize multiple automation testing frameworks like Selenium or Puppeteer. The testers can begin this process by creating the test scripts which will navigate through the website and interact with the elements for verifying their functionality.

While the testers are working on Internet Explorer, they must ensure that the automation test scripts are compatible with all the unique features and rendering patterns, including different JavaScript behaviors in this browser.

To further elevate this process, the app developers can integrate AI-powered test orchestrations and execution platforms like LambdaTest, which can run all the automated test suites on more than 300 using different combinations of browser versions, operating systems, and real devices. While this platform, the app developers can intelligently orchestrate the test cases with artificial intelligence and machine learning.

LambdaTest also simplifies the test reporting and debugging process using active test logging and comprehensive test reports, which consist of various screenshots and videos.

2. Polyfills and Transpilation

Using Polyfills, the testers can fill the gaps in browser support by adding missing features. For Internet Explorer, the developer should consider using Polyfills for CSS Grid, Flexbox, and other modern CSS features. The testers can also use JavaScript transpilers like Babel which can convert the ES6+ code into ES5.

This conversion process will ensure compatibility with all the older browsers and browser versions, including Internet Explorer. During this process, the app testers must also remember to convert the application source code content into the supported versions.

3. Continuous CSS and JavaScript

The developers and testers can use conditional statements for searching different CSS and JavaScript files. These statements will be adjusted based on the browser. For example, while using Internet Explorer, the developers can provide fallbacks or alternative styles and scripts that will accommodate the limitations of this browser.

To adjust all these parameters, the application testers must enter a set of codes in the terminal window during the test execution process. We have mentioned a sample code that the new testers can use as a point of reference.

4. CSS Hacks and Workarounds

Although CSS hacks aren’t recommended as a primary solution for ensuring compatibility with Internet Explorer, sometimes CSS hacks are necessary to fix certain layout issues that might be present in Internet Explorer. In such instances, the developers can use conditional CSS statements or CSS hacks sparingly.

By sparingly using the CSS statements, the testers can ensure that the code doesn’t become harder to maintain in the long run. The testers must reuse huge segments of the existing code while rolling out subsequent updates to the website or web application.

5. Modernizr

Modernizr is basically a JavaScript library that detects browser features. Using this library, the testers can adopt the test code accordingly based on the browser or the rendering environment. The testers can also use it to check for support of special features in Internet Explorer.

Depending on the incompatible features the testers might encounter during this process, they can apply appropriate fallbacks or Polyfills to resolve it before the app is forwarded to the deployment phase.

Using the following command, the application developers can initiate this process.

6. User-Agent Testing

Although it is not a fullproof process, the testers can use the user agent strings for detecting whether the user is using Internet Explorer or applying specific fixes or workarounds. Once this process is initiated, the system will automatically run the test instances and look for workarounds for fixing incompatible issues or non-rendering features on Internet Explorer.

To begin this process, the tester simply has to enter the following command in the terminal window.

7. Continuous Integration Testing

It is important for the testers to integrate compatibility testing into their continuous integration and continuous deployment pipeline. This approach will ensure that any changes do not break the compatibility of the web app on Internet Explorer. For this process, the testers can use dedicated tools like Jenkins or TravisCI.

These tools also allow automate this process across different browser environments so that the system can run the test instances as per the requirements. The integration of this pipeline also ensures that the app testers can initiate and execute the developing and testing phases simultaneously to massively reduce the development cycle and quickly deliver the finished product.

 Finally, it also allows the developers and testers to detect crucial errors in the app and resolve them at the earlier phase before they can turn into serious concerns and affect the app’s functioning.

Best Practices for Compatibility Testing on Internet Explorer Online

The following practices will ensure that the developers and testers can utilize the full potential of their compatibility test cases on Internet Explorer:

• It is important for the developers to streamline the testing process before initiating it. For instance, the testers can find out the most popular versions of Internet Explorer within the target audience and adjust the testing parameters accordingly.

• The app testers must download all the required testing files and dependencies from official websites to avoid any malicious attacks or possibilities of data leaks.

• It is important to maintain the proper balance between manual testing and automation testing to ensure dependable and non-flaky test results. For instance, the testers must automate those test instances that are repetitive and do not require any change of data inputs.

• It is important to maintain a thorough documentation of all the app changes, test results, and implemented resolutions. This approach will not only streamline the app delivery process but also ensure that the app testers can avoid previously documented errors in future app iterations.

• While implementing automation testing, developers and testers must go through the official documentation of their chosen automation testing framework. This documentation will consist of various features and methods that might be relevant depending on the app development project.

The Conclusion

Although Internet Explorer might become obsolete in the coming years, its compatibility challenges will persist for modern testers. So, by deploying advanced compatibility testing techniques that we discussed in this article, the testers can ensure that the website functions properly across all versions of Internet Explorer that are currently operational.

Ignoring Internet Explorer compatibility can lead to poor user experiences and can also alienate a massive segment of the audience. This trend will be even more relevant in enterprise settings where Internet Explorer is a hugely important component. So, by embracing these advanced techniques, the developers can maintain compatibility while still being able to use the advanced web technologies.

Finally, it is worth remembering that ensuring browser compatibility isn’t only about supporting legacy systems but also delivering a seamless experience to all users regardless of their browser choice.

With the evolution of web app development, the testers have to ensure the compatibility of their web apps on multiple browsers and devices. This is a critical parameter to provide the optimal end-user experience and maintain a positive brand image. Developers can use Microsoft Edge online to guarantee the functionality of their app on the Microsoft Edge web browser.

This article will explore some of the most significant challenges of testing modern web apps on the Microsoft Edge browser. We will also go through some of the most important tips and practices that can help the testers streamline their testing process and eventually overcome these challenges.

Understanding Microsoft Edge Online

Microsoft Edge Online is a web browser developed and maintained by Microsoft. This web browser has received significant attention due to its security features, performance, and seamless integration with all the other available Microsoft services. This browser is mainly built on the Chromium open-source project.

The Chromium project makes the Microsoft Edge browser online compatible with a wide range of web standards and technologies currently operational. However, like any other browser in the present era, Microsoft Edge Online also has unique iterations and differences that the developers must account for while running the compatibility test cases.

Challenges in Testing for Edge Compatibility

While executing the compatibility test cases on Microsoft Edge online, the testers will encounter several challenges that might hinder the overall testing phase. So, to help the developers prepare themselves, we have mentioned some of the most common challenges that they will encounter in this process:

• Diverse User Base

The Microsoft Edge online browser has a huge user base. Moreover, the user base of this web browser is hugely diverse as it consists of individual and enterprise users. So, ensuring the compatibility of multiple web-based features across different user environments becomes a complex and challenging process.

• Version Differences

Microsoft rolls out frequent updates to the Edge online browser. However, different users may be using various versions of this browser. A survey even shows that over 75% of end users need to update their browsers at any time. So, app developing companies have to ensure the compatibility of their apps on all the functional versions of this browser.

This process is critical to guarantee a consistent end-user experience for a diverse user base.

• Legacy Edge

Although Microsoft Edge has transitioned to the Chromium engine, many users still need to be fixed on the legacy version of Edge. This version is also popularly known as the edge HTML. So, the testers must account for these users and implement backward compatibility per the testing requirements.

• Feature Variations

Although Microsoft Edge Online is based on the Chromium browser, Edge may have multiple features and behavior variations compared to other browsers. Some of the most popular alternatives include Google Chrome or Opera.

Therefore, the testers must account for all these variations and implement the necessary changes in the test cycles to identify and address any compatibility issues in the app architecture.

Optimizing the Testing Strategies

Now that we have understood some of the significant challenges of implementing web app testing on Microsoft Edge let us discuss some of the most advanced testing strategies that can help the testers solve these issues:

1. Using Microsoft Edge DevTools

Microsoft Edge DevTools will provide a suite of different tools for web testers. Using these tools, the testers can debug, profile, and test their respective web apps per their testing requirements. Using these tools, the testers can simulate various device configurations, inspect CSS and HTML elements, debug JavaScript, and analyze network performance.

The testers should also familiarize themselves with these tools to utilize the debugging and testing capabilities significantly to improve the overall efficiency of the testing life cycle.

2. Integrating Automation Testing

Modern web apps consist of thousands of different elements that significantly improve the overall efficiency of the app’s functioning. So, it is essential for the developers to individually verify the functioning of all these elements to ensure the app is ready to be forwarded to the production phase.

However, if the developers wanted to implement manual testing for all these elements, it would take several months to complete the entire development cycle. So, the testers must implement automation testing to run multiple test instances based on all the predetermined testing parameters.

The testers can also use various popular automation testing tools like Selenium, Playwright, and WebDriverIO to automate the testing phases. Using this approach, the testers can also run the test cases on different versions of Microsoft Edge to detect compatibility issues at the earlier stages of the development cycle.

Moreover, by integrating automation testing, the app testers can save a lot of time in the development life cycle, which they can further invest in creating new features that can be rolled out in the future iterations of the app. Therefore, automation testing has an indirect role in improving the quality of modern web apps.

3. Utilizing the Compatibility Tools

Currently, the testers will find several online tools available in the market that help identify severe compatibility issues specific to Microsoft Edge online. For example, Microsoft’s native Sonar tool analyzes multiple websites for compatibility with Edge and also provides detailed reports on some other potential issues that might be present on them.

Moreover, the developers can also use cloud platforms like LambdaTest to test their websites on various browsers, including Microsoft Edge, across different platforms and devices. 

LambdaTest is an AI-powered test orchestration and execution platform that lets you run manual and automated tests at scale with over 3000+ real devices, browsers, and OS combinations. It allows testers to do automated web testing on more over-rating systems and real device cloud. While using the combinations platform, the testers can utilize advanced features like artificial intelligence and machine learning for better test management.

After executing the test instances, LambdaTest will automatically generate comprehensive test reports, including several screenshots and videos, which will help the developers quickly debug the faulty elements of the application.

4. Utilizing Feature Flags and Polyfills

Developers can use feature flags and Polyfills to address the differences in browser features and behaviors. The testers can selectively turn certain features on or off using feature flags based on the user’s experience. The final goal for this process is to ensure a consistent experience across different testing environments.

On the other hand, the testers can use Polyfills to provide fallbacks for missing or incomplete browser features. The ultimate goal of this process is to ensure compatibility with older versions of Edge or other older browsers that lack support for certain facilities, including modern ones.

In short, by using feature flags and Polyfills, the testers can continue using advanced software development practices while maintaining compatibility with outdated or legacy browser versions.

5. Performing User Agent Testing

User Agent testing simulates different user agents to ensure that the website functions correctly across various devices and browsers. Although user agent strings can be spoofed using browser extensions or developer tools, testing the website under different user agent conditions is essential.

By deploying this approach, the application testers can catch any issues that might be prevalent within the application’s architecture currently being developed and tested.

Best Practices for Testing Microsoft Edge Online

Now that we have understood some of the best strategies for testing Microsoft Edge online, let us go through some of the best practices that the developers and testers can deploy in this process further to elevate the efficiency and accuracy of the test instances:

• Maintaining the Testing Balance

We mentioned earlier that it is essential for app testers to integrate automation testing in the modern testing cycles due to the total number of test cases and their complexity. However, the tester should also understand that certain testing instances are massively dependent on the expertise of human developers.

For example, it is almost only possible to execute exploratory testing and visual element comparison testing with the involvement of human testers. So, we advise the app companies to maintain a test plan to create the proper balance between manual and automation testing.

As a starting step, the app testers should only automate those test instances that consist of repetitive test cycles and do not involve a lot of variations in the form of data inputs.

• Understanding the Target Audience

The testers need to understand their target audience thoroughly because there are thousands of versions of Microsoft Edge online. This data will help them to shortlist the most important browsers that are currently popular in this segment. So, using this information, the testers can massively streamline the overall testing cycle.

Moreover, by analyzing the target audience requirements, app testers can integrate various features to help them personalize the test instances and expand the audience reach even more.

• Understanding the Importance of Real Device Testing

Most modern app-developing companies rely on simulation software to understand how web apps react while running on multiple devices. However, the tester should also realize that simulation software or virtual environments cannot replicate the physical parameters of a device.

So, it becomes almost impossible for the testers to understand how the app reacts to low battery, user interaction errors, or a broken display. Therefore, it is crucial to integrate accurate device testing through in-house device test benches or cloud platforms to avoid flaky or unreliable test results.

• Maintaining Data Integrity

While executing the test cases on Microsoft Edge online, the testers must download all the required dependencies from official websites to avoid any possibilities of malicious attacks or data leaks.

The Final Verdict

Based on all the points discussed in this article, ensuring compatibility with Microsoft Edge online is crucial for delivering a seamless web experience to multiple users. The testers must understand the challenges of Edge compatibility and optimize their testing cycles accordingly.

It is also essential for the testers to streamline their development process and catch compatibility issues at the earlier stages of the development cycle.
