How can I get site's favicon using Selenium - selenium

Question

I need to get web site's favicon.
How can I do that?

Answer 1

You won't be able to get the favicon with Selenium you would have to use another program to grab it. The only way you would be able to get it is if your website rendered the favicon.ico as a link such as
<link rel="shortcut icon"
href="http://example.com/myicon.ico" />
However typically websites just store the favicon.ico in the root directory and on page request the browser retrieves it and drops it in the address bar or tab or wherever favicons are used. If this is how your favicon is rendered then there will be no code or anything to search for with Selenium.
Also the above code while it does work has some buggy support for IE7.

Answer 2

You don't need Selenium.
Just request the site's home page and use an HTML parser to find a <link rel="shortcut icon" href="..."> tag.
If you don't find any such tag, try /favicon.ico.

Answer 3

Here is a bit crazy but working solution:
get the favicon image opened in a web page (and hence reachable with selenium) with the help of "http://www.google.com/s2/favicons". There are other services which provide a similar functionality, see:
Get website's favicon with JS
use cssneedle package to compare the resulting favicon with a pre-saved one
Needle is a tool for testing your CSS with Selenium and nose.
It checks that CSS renders correctly by taking screenshots of portions
of a website and comparing them against known good screenshots. It
also provides tools for testing calculated CSS values and the position
of HTML elements.
In other words, we are going to compare favicon images.
Example implementation (python):
from needle.cases import NeedleTestCase
class FavIconTestCase(NeedleTestCase):
def test_so(self):
self.driver.get('http://www.google.com/s2/favicons?domain=www.stackoverflow.com')
self.assertScreenshot('img', 'so-favicon')
