When it comes to testing your website across IE, it is no less than a nightmare for both testers as well as developers. With Windows 10, Microsoft introduced Edge, a completely different browser where the code behind IE was completely rewritten.

The new browser now supports advanced web development frameworks like Bootstrap and the latest version of ECMAScript. No matter how much-updated browser is released by Microsoft, client or business requirement may need a website to be compatible across older versions of IE as well as Edge. This proves to be a challenge for testers, since they may not have older versions of IE installed in their machine.

Let’s take a look at what to do when your project requires cross-browser compatibility testing on IE and testing on Edge.

Multiple Versions Installed in Virtual Machine

If the budget allotted for cross browser compatibility testing your application is sufficient, it is ideal to install multiple virtual machines and install different versions of IE and Edge in each of them. This will prevent any complications caused by the rendering engine and the tester can ensure that when testing on IE or testing on Edge is executed, all the functionalities of your website are running properly in different versions of the browser.

Using the Browser’s Developer Tools

The recent versions of IE have inbuilt developer tools, using which the developer can check how the website is rendered across old versions. It should be remembered that this feature is available only in IE 11 and Edge does not have this feature yet. So, testing on Edge is not of many advantages. Also, this feature may not work properly for certain functionalities since the rendering engine of the original version of the browser may work differently than the emulated scenario. In conclusion, this tool is ideal for replicating a bug but not at all useful while unit testing on IE or testing on Edge of the application is carried out.

Using Cloud Testing Platforms

A cloud-based cross-browser compatibility testing platform like LambdaTest provides you the opportunity to flawlessly test your website across multiple versions of Edge and IE, running simultaneously in different systems. The best feature is, all the tests are done on real-time and not an emulated environment. All you need to do is, open LambdaTest on your browser window, select the browser versions, enter the URL of your site and start the test. Apart from testing on IE, you can also run testing on Edge (different versions, including the beta versions).

IETester

Being open source, IETester is a favorite among all testers because of its ability to render your desired site across multiple versions of Internet Explorer. The application supports even lower IE versions like 5.5. It works across multiple version of windows and the fact that makes it an all-time favorite among testers is that it does not create any shortcut.

All you need to do is launch the program, select the browser versions and start the test. The website will open across multiple tabs, each representing a different version where you can execute cross-browser compatibility testing on IE for your application. The only constraint is that, for debugging or viewing the source code, you need to install DebugBar, an additional plugin released by the developers of this application.

MultipleIE

For testers using Windows XP, the ideal way to test your application across different IE versions is by using MultipleIE. It works by installing multiple standalone versions of IE on your system. It cannot be used on Windows 7 and above because the developers stopped maintaining this application. However, when your cross-browser compatibility testing scenarios require you to test your website for Windows XP, this tool is ideal.

Test IE

This is not an application, but a plugin available at Google Chrome web store. Using this, the tester can execute cross-browser testing on IE, ranging from v6 to v11. All you have to do is open the plugin located at the toolbar, choose the browser version that you want to test and start. Once done, the page will be reloaded and you will get a view of how the page will appear on the desired browser version.

Utilu IE Collection

This software is widely popular for running cross-browser compatibility testing on IE across different versions of internet explorer. This is because it comes with a complete package of all the versions of IE that has been released. This includes older versions like IE 1 or 2. Scenarios may arise when the desired version is not compatible with the operating system. This will be detected by the installer which will install only the browser versions that are supported. The only drawback is lack of a single-click application.

IENetRenderer

This is just another cross-browser compatibility testing tool like TestIE. However, it does not render an entire webpage. It only emulates a screenshot of how the page will look like when rendered using the selected browser. This is not useful for debugging bugs, but when you need to run visual regression testing on IE across different versions, there is no better tool than this one.

Apart from the tools and platforms mentioned above, there are many others, using which, cross-browser compatibility testing on Edge and IE can be executed. Start executing test cases and do let us know if you come across any efficient tool or platform that does the same.
