checkDirectoryExists: Check for existence and access rights of directories

Description

Check for existence and access rights of directories

Usage

checkDirectoryExists(x, access = "")
check_directory_exists(x, access = "")
assertDirectoryExists(x, access = "", .var.name = vname(x), add = NULL)
assert_directory_exists(x, access = "", .var.name = vname(x), add = NULL)
testDirectoryExists(x, access = "")
test_directory_exists(x, access = "")
expect_directory_exists(x, access = "", info = NULL, label = vname(x))
checkDirectory(x, access = "")
assertDirectory(x, access = "", .var.name = vname(x), add = NULL)
assert_directory(x, access = "", .var.name = vname(x), add = NULL)
testDirectory(x, access = "")
test_directory(x, access = "")
expect_directory(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 assertDirectoryExists/assert_directory_exists return x invisibly, whereas checkDirectoryExists/check_directory_exists and testDirectoryExists/test_directory_exists return TRUE. If the check is not successful, assertDirectoryExists/assert_directory_exists throws an error message, testDirectoryExists/test_directory_exists returns FALSE, and checkDirectoryExists returns a string with the error message. The function expect_directory_exists always returns an expectation.
