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.
Usage
test_examples(path = "../../man")
test_example(path)
Arguments
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.
