\usage{
expectation(type, message, srcref = NULL, trace = NULL)
new_expectation(
type,
message,
...,
srcref = NULL,
trace = NULL,

)
exp_signal(exp)

\arguments{
\item{type}{Expectation type. Must be one of "success", "failure", "error",
"skip", "warning".}
\item{message}{Message describing test failure}
\item{srcref}{Optional \code{srcref} giving location of test.}
\item{trace}{An optional backtrace created by \code{\link[rlang:trace_back]{rlang::trace_back()}}.
When supplied, the expectation is displayed with the backtrace.}
\item{...}{Additional attributes for the expectation object.}
\item{.subclass}{An optional subclass for the expectation object.}
\item{exp}{An expectation object, as created by
\code{\link[=new_expectation]{new_expectation()}}.}
\item{x}{object to test for class membership}
}
\description{
For advanced use only. If you are creating your own expectation, you should
call \code{\link[=expect]{expect()}} instead. See \code{vignette("custom-expectation")} for more
details.
}
\details{
Create an expectation with \code{expectation()} or \code{new_expectation()}
and signal it with \code{exp_signal()}.
