SVG Icon
Checks that a SVG icon is defined and formatted correctly.
The SVG image format is a vector based image that allows it to scale up and down gracefully. This means that one SVG icon can be used for any size that the browser needs. This favicon format is gaining in popularity and is now the recommended way to deploy a favicon for your website. Here is the link tag that you should include on your website:
<link rel="icon" href="/icon.svg" type="image/svg+xml">
This test will check for the presence of a <link> tag containing a SVG icon and then download the image to make sure it exists.
