R devel - Jul 2006 - Package Unit Testing

Hello,

Do we have like an official unit testing framework for packages? Like
we do R CMD check, and say the scripts in <pkg>/test are executed? Or
do we roll out our own outside the package?

Thanks,
M. Manese

The scripts are executed with R CMD check. What else do you need?

yes.  Just it's  "./tests",  not './test'.

More specifically, all ./tests/*.R are executed and for those
foobar.R for which there's a  foobar.Rout.save  file,
the output is (R CMD Rdiff)ed agains the result of running foobar.R

All this should be pretty obvious from the manual
"Writing R Extensions".  
What was it in there that was not clear enough?

Some people use the 'RUnit' package in addition or -- unfortunately --
alternatively to the "official" testing procedures via the
"./tests" directory.
