skip_if()
and skip_if_not()
allow you to skip tests, immediately
concluding a test_that()
block without executing any further expectations.
This allows you to skip a test without failure, if for some reason it
can't be run (e.g. it depends on the feature of a specific operating system,
or it requires a specific version of a package).
See vignette("skipping")
for more details.

A message describing why the test was skipped.
Boolean condition to check. skip_if_not()
will skip if
FALSE
, skip_if()
will skip if TRUE
.
Name of package to check for
Minimum required version for the package
A string with a hostname to lookup
Character vector of one or more operating systems to skip on.
Supported values are "windows"
, "mac"
, "linux"
, and "solaris"
.
Character vector of one or more architectures to skip on.
Common values include "i386"
(32 bit), "x86_64"
(64 bit), and
"aarch64"
(M1 mac). Supplying arch
makes the test stricter; i.e. both
os
and arch
must match in order for the test to be skipped.
R message identifier used to check for translation: the default
uses a message included in most translation packs. See the complete list in
R-base.pot
.
skip_if_not_installed("pkg")
skips tests if package "pkg" is not
installed or cannot be loaded (using requireNamespace()
). Generally,
you can assume that suggested packages are installed, and you do not
need to check for them specifically, unless they are particularly
difficult to install.
skip_if_offline()
skips if an internet connection is not available
(using curl::nslookup()
) or if the test is run on CRAN. Requires
{curl} to be installed and included in the dependencies of your package.
skip_if_translated("msg")
skips tests if the "msg" is translated.
skip_on_bioc()
skips on Bioconductor (using the IS_BIOC_BUILD_MACHINE
env var).
skip_on_cran()
skips on CRAN (using the NOT_CRAN
env var set by
devtools and friends).
skip_on_covr()
skips when covr is running (using the R_COVR
env var).
skip_on_ci()
skips on continuous integration systems like GitHub Actions,
travis, and appveyor (using the CI
env var).
skip_on_os()
skips on the specified operating system(s) ("windows",
"mac", "linux", or "solaris").
