R/expect-setequal.R
expect_setequal.Rdexpect_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 every element of x is in y
(i.e. x is a subset of y).
expect_mapequal(x, y) tests that x and y have the same names, and
that x[names(y)] equals y.
expect_setequal(object, expected)
expect_mapequal(object, expected)
expect_contains(object, expected)
expect_in(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.
Note that expect_setequal() ignores names, and you will be warned if both
object and expected have them.
