expect_success(expr)
expect_no_success(expr)
expect_failure(expr, message = NULL, ...)
expect_snapshot_failure(expr)
expect_no_failure(expr)
show_failure(expr)
}
\arguments{
\item{expr}{Code to evalute}
\item{message}{Check that the failure message matches this regexp.}
\item{...}{Other arguments passed on to \code{\link[=expect_match]{expect_match()}}.}
}
\description{
\itemize{
\item \code{expect_sucess()} and \code{expect_failure()} check that there's at least
one success or failure respectively.
\item \code{expect_snapshot_failure()} records the failure message so that you can
manually check that it is informative.
\item \code{expect_no_success()} and \code{expect_no_failure()} check that are no
successes or failures.
}
Use \code{show_failure()} in examples to print the failure message without
throwing an error.
