expect_vector()
is a thin wrapper around vctrs::vec_assert()
, converting
the results of that function in to the expectations used by testthat. This
means that it used the vctrs of ptype
(prototype) and size
. See
details in https://vctrs.r-lib.org/articles/type-size.html
expect_vector(object, ptype = NULL, size = NULL)
object | Object to test. Supports limited unquoting to make it easier to generate readable failures within a function or for loop. See quasi_label for more details. |
---|---|
ptype | (Optional) Vector prototype to test against. Should be a size-0 (empty) generalised vector. |
size | (Optional) Size to check for. |
