Defined in:
lib/riot/assertion_macros/same_elements.rb

Overview

Asserts that two arrays contain the same elements, the same number of times.

asserts("test") { ["foo", "bar"] }.same_elements(["bar", "foo"])
should("test") { ["foo", "bar"] }.same_elements(["bar", "foo"])

Maybe you just want to make sure two sets arent't the same:

denies("test") { ["foo", "bar"] }.same_elements(["baz", "boo"])

def devaluate(actual, expected)
  same = (Set.new(expected) == Set.new(actual))
  same ? fail(expected_message.elements(expected).not_to_match(actual)) : pass(new_message.has_same_elements_as(expected))
end

- (Array) evaluate(actual, expected)

Supports positive assertion testing. This is where magic happens.
