The part I'm looking at shows this:
Package/Case -- 32-WFQFN Exposed Pad
Supplier Device Package -- 32-MLP
What are some of the ways to test this out on a breadboard? It would be great not have to solder/desolder I found some adapters but they're pricey.

Wondering what the typical solution is for this problem.

Best bet is to either bit to bullet and solder it to a qfn32 to dip adaptor or find a preassembled breakout board on spark fun. Tindie, eBay, etc for the device that to want to test.
I would not go the socket approach.
What part is it anyway, surely someone of this forum has used it and might have some breakout board in mind.

basically 2 effective choices as you found out. a solderable breakout board: http://www.adafruit.com/products/1163 (http://www.adafruit.com/products/1163)
or your socketed board. You can get some for possibly slightly cheaper on ebay. seems to be, if you use the socket like 20+ times, it's paid for itself over the solderable breakout.

With things trending toward SMT I'm surprised there aren't more solutions/options. I may try to make one that are pressed in by hand then extracted with the special tool that goes in at the corner. It's cheaper at least. I was looking for something like those simple ZIF sockets used for CPUs.
I think there's a lot of room for improvement on the current offering of solutions for doing SMT with breadboards.

PLCC socket? Those probably won't work for any *FN package.
There are QFN sockets that work on the same principle as BGA ones, but they tend to be rather expensive (http://www.test-socket.com/).

I thought I saw a part that allowed a *FN package to be pressed in then extracted with a small tool. It's very possible that I was looking at a PLCC socket. I need to find a page that has hi-res photos of the different types because the data sheet photos are not real photos they are just renderings.
