I disagree. Third Party testers have no vested interest in whether or not the items pass. Company employees do. While Mattel may not be going into it with the notion of "getting away with something", it could be very easily abused later on. And without third party testing, there is nothing to stop them.

It also could depend on whether Mattel (for example) owns the factories they use. I don't know if they do or not.
Where I work, we don't. Technically, we purchase the products we import at the point that they're loaded on the boats to come across the ocean. Up until then, they're the factory's problem. If a product fails testing because it wasn't made to our specifications, the factory bears the cost of remaking and resubmitting the product and paying all additional fees until it passes.
So you're right- if anything, it could be in the tester's best interest to be really super picky, so somebody has to pay for more tests! But if the importing corporation isn't bearing the burden of that, they don't care either, except for getting really annoyed when shipping deadlines are missed because of it.
Component testing, by the way, almost eliminates this problem! :-)
(shameless plug for component testing.)
We also do our own auditing of the factories before we'll do business w/them, to make sure there aren't any environmental and/or human rights issues. There are no guarantees, unfortunately, but it's usually a good indication that they're paying attention to doing things right in other aspects of their business too. (I'm not personally involved with that, but I think it's really important. I don't want to work here if what we do is hurting anybody.)
