Conditionally stop testing a tinytest test file if running
under covr. This is determined by checking if the environment
variable “R_COVR” set and is a non-FALSE value
skip_on_covr()
exit_on_covr()If called within a tinytest test running under
covr, triggers an exit condition; otherwise, either a
string saying “On covr” or NULL invisibly
tinyexpect provides both “skip_” and “exit_”
versions of “stop testing” functions due to the different philosophies
of tinytest and testthat; in testthat, tests
are encapsulated by test_that() to create smaller
testing units within a single test file. As such, if a series of tests need
to be passed over for some reason, it makes sense to “skip” a
test_that() block and move on to the next block
tinytest, however, treats each test file as a testing unit. Each
file in inst/tinytest is equivalent to a testthat
test_that() block; as such, if a series of tests need
to be passed over for some reason, it makes sense to “exit” a test
file and move on to the next file in inst/tinytest
In order to provide compatibility with users transitioning from
testthat to tinytest, and to provide continuity with the
tinytest philosophy, tinyexpect provides both skip_-
and exit_- prefixed “stop testing” functions that work
identically to one another
testthat equivalent:
testthat::skip_on_covr()
Other "stop testing" functions:
skip(),
skip_if_not_installed(),
skip_on_bioc(),
skip_on_ci(),
skip_on_cran(),
skip_on_os()
withr::with_envvar(c(R_COVR = "true"), skip_on_covr())
#> [1] "On covr"
