expect_setequal {testthat}

R Documentation

Does code return a vector containing the expected values?

Description

• expect_setequal(x, y) tests that every element of x occurs in y, and that every element of y occurs in x.

• expect_mapequal(x, y) tests that x and y have the same names, and that x[names(y)] equals y.

Usage

expect_setequal(object, expected)

expect_mapequal(object, expected)

Arguments

object	Computation and value to compare it to. Both arguments supports limited unquoting to make it easier to generate readable failures within a function or for loop. See quasi_label for more details.
expected	Computation and value to compare it to. Both arguments supports limited unquoting to make it easier to generate readable failures within a function or for loop. See quasi_label for more details.

Details

Note that expect_setequal() ignores names, and you will be warned if both object and expected have them.

Examples

Run examples

expect_setequal(letters, rev(letters))
show_failure(expect_setequal(letters[-1], rev(letters)))

x <- list(b = 2, a = 1)
expect_mapequal(x, list(a = 1, b = 2))
show_failure(expect_mapequal(x, list(a = 1)))
show_failure(expect_mapequal(x, list(a = 1, b = "x")))
show_failure(expect_mapequal(x, list(a = 1, b = 2, c = 3)))
