expect_setequal: Do you expect a vector containing these 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_contains(x, y) tests that x contains every element of y (i.e. y is a subset of x).

• expect_in(x, y) tests that every element of x is in y (i.e. x is a subset of y).

• expect_disjoint(x, y) tests that no element of x is in y (i.e. x is disjoint from y).

• expect_mapequal(x, y) treats lists as if they are mappings between names and values. Concretely, checks that x and y have the same names, then checks that x[names(y)] equals y.

Usage

expect_setequal(object, expected)
expect_mapequal(object, expected)
expect_contains(object, expected)
expect_in(object, expected)
expect_disjoint(object, expected)

Arguments

object, 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

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)))
