Spyware/Adware Test Code

I am aware EICAR released (one lined) virii test code for the purposes of testing Anti-Virus software. However; does anyone know of any recognised test code which may be applied to Spyware killers (e.g. search and destroy)?

So far Google searches have proved fruitless or led to some dubious sites.

The simplest solution, of course, would be to visit a dozen XXX sites and get the real-deal - though having every machine flashing a pop-up of Britney Spears naked may induce severe fits of vomiting from both myself and colleagues :D

Any knowledge on this would be appreciated.
