YouTube description:

Webb Telescope's Backplane Pathfinder arrives at Ellington Field Joint Reserve Base in Houston. Engineers will test Pathfinder inside NASA's largest cryogenic vacuum chamber called Chamber A. NASA engineers off-load pathfinder and its shipping container from a US Airforce C-5 cargo plane and transport it to the Johnson Space Center and into Chamber A's cleanroom.

Test it for what?

It might help to start with what the Backplane Pathfinder actually is - it's a non-flight replica of the Webb telescope’s center backplane (that link has more info and pictures).

Chamber A allows simulating the cold environment the real telescope will face in space, and is the same vacuum chamber where Apollo spacecraft were tested.

Now, to answer your question: They are testing the test procedures for the real telescope! (source: NASA). I realise that doesn't exactly answer your question, but I haven't found details of the actual tests they plan to run... so as a distraction, here are some more images - http://jwst.nasa.gov/images_backplane.html
