Test code in a temporary directory.
Runs a test_that() unit test inside a temporary
directory to avoid writing to the user's file space.
This helps ensure compliance with CRAN policies.
Also isolates tar_option_set()
options and environment variables specific to targets
and skips the test on Solaris.
Useful for writing tests for
targetopia packages
(extensions to targets tailored to specific use cases).
tar_test(label, code)
label |
Character of length 1, label for the test. |
code |
User-defined code for the test. |
NULL (invisibly).
Other utilities to extend targets:
tar_assert,
tar_condition,
tar_dir(),
tar_language
tar_test("example test", {
testing_variable_cafecfcb <- "only defined inside tar_test()"
file.create("only_exists_in_tar_test")
})
exists("testing_variable_cafecfcb")
file.exists("only_exists_in_tar_test")Please choose more modern alternatives, such as Google Chrome or Mozilla Firefox.
