The tests for the Favicon and Logo code is not complete yet there are still a few more tests to be written:

1. Test wether or not the height and width properties are the same as they have been set to.
2. Test that the favicon works in every single app. The favicon works if the link to the favicon has link="icon" in it, and when you download it it is exactly the same as the image that you expect it to be (compare them byte by byte). For an example of how to do the download and compare to an existing image then look in here: https://studio.atlassian.com/source/browse/JST/trunk/studio-fireball/src/test/java/com/atlassian/studio/functest/TestLookAndFeel.java#r106417
3. Test that when you download the favicon and the Logo that the mime types that you get start with "image/"

That will make the favicon test robust.
