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

Examples

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