Silk Test Workbench does not automatically bring the browser into the foreground when recording actions against Microsoft Edge.

When testing with Microsoft Edge, the rectangle for the BrowserApplication is not absolute.

Silk Test Workbench does not support testing Apache Flex.

Silk Test Workbench does not provide native support for Microsoft Edge. You cannot test internal Microsoft Edge functionality. For example, in a test, you cannot change the currently displayed web page by adding text to the navigation bar. As a workaround, you can use API calls to navigate between web pages.

Silk Test Workbench does not support handling alerts and similar dialog boxes for Microsoft Edge.

Image clicks are only supported for Microsoft Edge Threshold 2 (build 25.10586) or later. If you are testing a web application on a prior version of Microsoft Edge, you can only use image verifications.

Silk Test Workbench does not support tabbing on Microsoft Edge. Tabs are recognized as windows.

If the replay of a visual test is slow, set the option Control capture under Tools > Options > Playback > Results > Visual test, to No. Otherwise, the playback might get very slow for rich Web pages, and might even result in a communication timeout.

When testing web applications on Microsoft Edge, Silk Test Workbench cannot locate meta-tags which include the http-equiv attribute. For example, Silk Test Workbench cannot locate the following meta-tag:

<meta http-equiv="content-type" content="text/html; charset=utf-8">

With Microsoft Edge, Silk Test Workbench does not support directly reading the currentStyle attribute of a DOM element. You can use the GetCssStyle method of the DomElement class to retrieve the computed CSS style with the specified style name.

When starting the interaction with a web application on Microsoft Edge, Silk Test Workbench closes any open instance of Microsoft Edge and starts a new browser. This new browser uses a temporary profile without add-ons and with an empty cache. This instance of Microsoft Edge is closed when shutting down the Open Agent or when starting to test another application outside Microsoft Edge.

With Microsoft Edge, Silk Test Workbench does not recognize the textContents attribute while recording actions or locators. However, you can use the textContents attribute in object maps and when replaying a test on Microsoft Edge.

Silk Test Workbench does not support properties in XPath expressions for Microsoft Edge. Only attributes are supported in XPath expressions.

Silk Test Workbench does not support the GetFocus method of the IMoveable class.

Silk Test Workbench does not support testing web applications which include a Content-Security-Policy HTTP header.
