You could add the following at the start of a script containing slow tests:
if (!identical(Sys.getenv("NOT_CRAN"), "true")) {
message("skipping slow tests")
q("no")
}
## slow tests follow here ...
Of course, you could use a different name for the environment variable,
e.g., "R_PKGNAME_ALL_TESTS", or test with as.logical() to allow both
"TRUE" and "true" values:
if (!isTRUE(as.logical(Sys.getenv("R_PKGNAME_ALL_TESTS")))) q("no")
Quitting from test scripts as above is frequently used in R's own test
suite, for example in the regression tests for message translations:
if (!capabilities("NLS")) {
message("no natural language support")
q("no")
}
Don't run such code in an interactive session if you don't want to quit
R. ;)
An alternative is the R CMD check --test-dir=inst/slowTests approach
mentioned in the WRE manual at
https://CRAN.R-project.org/doc/manuals/r-devel/R-exts.html#Checking-packages
.
