\name{expect_reference}

\title{Does code return a reference to the expected object?}
\usage{
expect_reference(
object,
expected,
info = NULL,
label = NULL,
expected.label = NULL
)
}
\arguments{
\item{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 \link{quasi_label} for
more details.}
\item{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 \link{quasi_label}.}
\item{label, expected.label}{Used to customise failure messages. For expert
use only.}
}
\description{
\code{expect_reference()} compares the underlying memory addresses of
two symbols. It is for expert use only.
}
\section{3rd edition}{
\ifelse{html}{\href{https://lifecycle.r-lib.org/articles/stages.html#deprecated}{\figure{lifecycle-deprecated.svg}{options: alt='[Deprecated]'}}}{\strong{[Deprecated]}}
\code{expect_reference()} is deprecated in the third edition. If you know what
you're doing, and you really need this behaviour, just use \code{is_reference()}
directly: \code{expect_true(rlang::is_reference(x, y))}.
