Defined in:

Overview

RSpec::Matchers class for testing hashes enclosed in an array.

Array of Hashes: each Hash should have key :name or :<collection.singularize>

Hash here (subject) is an instance of Hash, which is an element of an Array, and Array itself is a value of a Hash:

{ :foos => 
      [                               <--- subject
            { :foo (or :name) => ...,
              :bar => ...,
            },
            { :foo (or :name) => ...,
              :bar => ...,
            },
           ]
}
