If you get a requirement to disable PhantomJS on your Content Delivery environments, this trick will do it.
How PhantomJS is implemented with Sitecore:
Content Testing in Sitecore uses the Phantom JS tool for generation of the screenshot image files. In case you didn’t know, Sitecore has had screenshot generation features for quite some time. We use it to generate icons for items that you’ll be listing in the UI like renderings. These icon generation features are based on the
System.Windows.Forms.WebBrowser control built into .net. So why did we not use the existing screenshot features for Content Testing? In early testing we found discrepancies with the
WebBrowser uses Internet Explorer installed on the server where Sitecore is running. But the specific version that it uses isn’t always the latest. There are registry updates one can make to force the appropriate IE version, but this seemed like a big ask of users. This was one of the reasons we chose to use Phantom JS instead.
