The CRAN check on fedora gives me more detailed results now:
https://www.r-project.org/nosvn/R.check/r-devel-linux-x86_64-fedora-clang/rlibkriging-00check.html
.
It points a fairly strange issue (possibly due to recursive programming, that
remains to investigate), but anyway I can now circumvent the problem for CRAN.
In next "true" release, I will try to switch back to a testthat suitable
reporter instead of the enumerated tests in tests/, as you suggested.
So, thank you very much to all of you for your kind help and suggestions.
Yann & libKriging team.

I think CRAN output will only show you the reporter results if there's an
error. If it's a regular error, you get the last 13 lines. From your earlier
posting, it looks as though a timeout might give more. But even the last 13
lines should identify exactly which test was running when the timeout happened.
I probably wouldn't use the location reporter for routine runs, because it will
give a lot of output, and conceivably this will slow things down.
