These helper functions make it easier to test the examples in a package. Each example counts as one test, and it succeeds if the code runs without an error. Generally, this is redundant with R CMD check, and is not recommended in routine practice.

test_examples(path = "../..")

test_rd(rd, title = attr(rd, "Rdfile"))

test_example(path, title = path)



For test_examples(), path to directory containing Rd files. For test_example(), path to a single Rd file. Remember the working directory for tests is tests/testthat.


A parsed Rd object, obtained from tools::Rd_db() or otherwise.
