I am not proposing that the CPRT be a substitute for "decent tests." We still
need a a good set of tests for the whole MW product (not just the parser). Nor
would I recommend making a change to the parser and then immediately running
the CPRT. Any developer that isn't masochistic would first run the existing
parserTests and ensure it passes. Then, you probably want to run the modified
DumpHTML against a small random selection of pages in the WP DB. Only if it
passes those tests would you then run the CPRT for final assurance.
The CPRT I am proposing is about as good a test of the parser that I can think
of. If a change to the parser passes it using the Wikipedia database (currently
5 GB), then I would say for all practical purposes the changes made to the
parser do not regress it.

I don't understand this point. Would you elaborate?
