expect-compare: Expectation: is returned value less or greater than specified value?

Description

This is useful for ensuring returned value is below a ceiling or above a floor.

Usage

is_less_than(expected, label = NULL, ...)
expect_less_than(object, expected, ..., info = NULL, label = NULL,
  expected.label = NULL)
is_more_than(expected, label = NULL, ...)
expect_more_than(object, expected, ..., info = NULL, label = NULL,
  expected.label = NULL)

Arguments

expected

Expected value

label

For full form, label of expected object used in error messages. Useful to override default (deparsed expected expression) when doing tests in a loop. For short cut form, object label. When NULL, computed from deparsed object.

expected.label
