I like how easy it is for me as a user to find an existing test by searching through the list. Sometimes you can't figure out what exactly your problem is so having multiple tests makes this easier. Also, sometimes there are times when my results come back without giving much information about why it failed, which could be helpful. The interface isn't always intuitive and some things aren't available at first glance. You need to click around more than once before finding something.
