[Rd] Testing development code?

[Spencer Graves]

Hi, R Core Team: 

      How do you test the latest changes to the core R code?  Is it just 
"R CMD check"?  Or do you use other tools, like the perl "prove" module? 

      I ask, because I'm about to start developing routine testing for 
other (non-R) software, for which I can't do "R CMD check", and I'd like 
to know what you do. 

      Thanks,
      Spencer Graves
