expect_reference()
compares the underlying memory addresses of
two symbols. It is for expert use only.
expect_reference( object, expected, info = NULL, label = NULL, expected.label = NULL )
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. |
info | Extra information to be included in the message. This argument is soft-deprecated and should not be used in new code. Instead see alternatives in quasi_label. |
label | Used to customise failure messages. For expert use only. |
expected.label | Used to customise failure messages. For expert use only. |
expect_reference()
is deprecated in the third edition. If you know what
you're doing, and you really need this behaviour, just use is_reference()
directly: expect_true(rlang::is_reference(x, y))
