Arguments

the name using deparse and substitute.

Extra information to be included in the message for the testthat reporter.
See expect_that.

Value
Depending on the function prefix:
If the check is successful, the functions return TRUE. If the check
is not successful, assertAccess/assert_access
throws an error message, testAccess/test_access
returns FALSE,
and checkAccess returns a string with the error message.
The function expect_access always returns an
expectation.
