Testing Microsoft Edge’s Internet Explorer mode for site compatibility just got easier

Internet Explorer 11 will no longer be supported on some PCs starting June 15, 2022. Although Microsoft’s old browser was replaced years ago, some organizations still use it for legacy web content. To make it easier to use older web content on a modern browser, Microsoft Edge has an Internet Explorer mode. Now developers can use the Internet Explorer driver to test if their site works in Internet Explorer mode in Microsoft Edge.

Microsoft has worked with Project Selenium to facilitate site compatibility testing for Internet Explorer mode in Edge.

“With just a few modifications to an existing test that runs on Internet Explorer, you can run your tests in Internet Explorer (IE) mode in Edge,” Microsoft explains. “By running your tests in IE mode, you will be able to verify that any legacy web content that runs in Internet Explorer will work as expected in IE mode in Microsoft Edge.”

To run tests in Internet Explorer mode in Edge, a developer must have Microsoft Edge, Selenium 4 or later language bindings and Internet Explorer driver version 4.0.0.0 or later.

Microsoft explains how to get started and how to test in a recent blog post.
