I agree with Martin.  A mechanism to specify testing level would be the best.
Then CRAN can choose to set that variable to "3" say, with level 1 for extensive and 2 for 
usual.
   I'm quite willing to put up with the nuisance of print() enclosures.  I prefer it to 
having yet another way to subvert the evaluation model.

   I'm a believer in testing everything possible in my packages, and wear it it as a badge 
of honor that the survival package has 4 lines of R code in the tests directory for every 
3 in the R directory.  But CRAN only needs to run a small subset of this.
