@expectRaw creates an expectation for your example code, without adding
the next expression as the subject.
@expectRaw creates a testthat expectation.
Unlike @expect, it doesn't insert the subsequent expression as the first
argument.
#' @doctest
#'
#' x <- 2 + 2
#' @expectRaw equals(x, 4)
#'
#' f <- function () warning("Watch out")
#' @expectRaw warning(f())
Don't include the expect_ prefix.
The @expectRaw tag and code must fit on a single line.
Other expectations:
expect-tag,
snap-tag
