`expect_setequal()` Absent/Needs wording

[jmbarbone]

testthat/R/expect-setequal.R

Lines 53 to 54 in 2a0c29b

	if (length(act_miss)) sprintf("Needs: %s", values(act_miss)),
	if (length(exp_miss)) sprintf("Absent: %s", values(exp_miss))

The language for errors in expect_setequal() seems a little off. To me, both "Absent" and "Needs" convey the same thing.

Would it make more sense for "Needs" to be something like "Extra", to convey that there's an unexpected value?

library(testthat)
expect_setequal(object = 1:3, expected = 1:2)
#> Error: Expected `1:3` to have the same values as `1:2`.
#> Actual: 1, 2, 3
#> Expected: 1, 2
#> Needs: 3
expect_setequal(object = 1:2, expected = 1:3)
#> Error: Expected `1:2` to have the same values as `1:3`.
#> Actual: 1, 2
#> Expected: 1, 2, 3
#> Absent: 3
