As I understand it, it works like this:
You can use your WHQL signing key to test-sign your components and add the
"Microsoft Test Root Authority" signing certificate to the "trusted root
authorities" certificate store on your test system.
This will then cause PUMA to load the component, but in "test mode."
Apps that pass the "allow test mode" flag (test apps) will then work. (Apps
that have access to real-live production content [production apps] will *not*
pass the flag, and the APIs will [correctly] fail.)
Once everything is tested and working you can submit through WHQL, sign the
relevant contracts (Exhibit B), and get a "real" signature. Production apps
will then work with your components even with production content.
For an example of passing a "test mode" flag (in this case, to the Trusted
Audio Drivers system) see:

Well, if this wasn't true, it would mean that you would be able to
process protected audio data without any clearance from anyone (just by
running the APO in the test environnement), which would defeat the whole
purpose of PUMA.
