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)

Arguments

label

Character of length 1, label for the test.

code

User-defined code for the test.

Value

NULL (invisibly).
