expect_access(x, access = "", info = NULL, label = vname(x))
Arguments
x
[any]
Object to check.
access
[character(1)]
Single string containing possible characters ‘r’, ‘w’ and ‘x’ to
force a check for read, write or execute access rights, respectively.
Write and executable rights are not checked on Windows.
.var.name
[character(1)]
Name of the checked object to print in assertions. Defaults to
the heuristic implemented in vname.
add
[AssertCollection]
Collection to store assertion messages. See AssertCollection.
info
[character(1)]
Extra information to be included in the message for the testthat reporter.
See expect_that.
label
[character(1)]
Name of the checked object to print in messages. Defaults to
the heuristic implemented in vname.
Value
Depending on the function prefix:
If the check is successful, the functions
assertAccess/assert_access return
x invisibly, whereas
checkAccess/check_access and
testAccess/test_access 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.
