\arguments{
\item{x}{[any]\cr
Object to check.}
\item{classes}{[\code{character}]\cr
Class names to check for inheritance with \code{\link[base]{inherits}}.
\code{x} must inherit from all specified classes.}
\item{ordered}{[\code{logical(1)}]\cr
Expect \code{x} to be specialized in provided order.
Default is \code{FALSE}.}
\item{cloneable}{[\code{logical(1)}]\cr
If \code{TRUE}, check that \code{x} has a \code{clone} method. If \code{FALSE}, ensure that
\code{x} is not cloneable.}
\item{public}{[\code{character}]\cr
Names of expected public slots. This includes active bindings.}
\item{private}{[\code{character}]\cr
Names of expected private slots.}
\item{null.ok}{[\code{logical(1)}]\cr
If set to \code{TRUE}, \code{x} may also be \code{NULL}.
In this case only a type check of \code{x} is performed, all additional checks are disabled.}
\item{.var.name}{[\code{character(1)}]\cr
Name of the checked object to print in assertions. Defaults to
the heuristic implemented in \code{\link{vname}}.}
\item{add}{[\code{AssertCollection}]\cr
Collection to store assertion messages. See \code{\link{AssertCollection}}.}
\item{info}{[\code{character(1)}]\cr
Extra information to be included in the message for the testthat reporter.
See \code{\link[testthat]{expect_that}}.}
\item{label}{[\code{character(1)}]\cr
Name of the checked object to print in messages. Defaults to
the heuristic implemented in \code{\link{vname}}.}
}
\value{
Depending on the function prefix:
If the check is successful, the functions
\code{assertClass}/\code{assert_class} return
\code{x} invisibly, whereas
\code{checkClass}/\code{check_class} and
\code{testClass}/\code{test_class} return
\code{TRUE}.
If the check is not successful,
\code{assertClass}/\code{assert_class}
throws an error message,
\code{testClass}/\code{test_class}
returns \code{FALSE},
and \code{checkClass}/\code{check_class}
return a string with the error message.
The function \code{expect_class} always returns an
\code{\link[testthat]{expectation}}.
