Check the operating system

checkOS(os)

check_os(os)

assertOS(os, add = NULL, .var.name = NULL)

assert_os(os, add = NULL, .var.name = NULL)

testOS(os)

test_os(os)

expect_os(os, info = NULL, label = NULL)

Arguments

os: [character(1)]
Check the operating system to be in a set with possible elements “windows”, “mac”, “linux” and “solaris”.
add: [AssertCollection]
Collection to store assertion messages. See AssertCollection.
.var.name: [character(1)]
Name of the checked object to print in assertions. Defaults to the heuristic implemented in vname.
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

assertOS/assert_os return

x invisibly, whereas

checkOS/check_os and

testOS/test_os return

TRUE. If the check is not successful,

assertOS/assert_os

throws an error message,

testOS/test_os

returns FALSE, and checkOS/check_os

return a string with the error message. The function expect_os always returns an

expectation.

Examples

testOS("linux")
#> [1] TRUE
