# These matchers are a syntactic hack to provide more readable expectations for# an Enumerable object.## They take advantage of the `all?`, `none?`, and `one?` methods, and the fact# that RSpec provides a `be_something` matcher for all predicates.## Example:## # Ensure exactly one object in an Array satisfies a condition# expect(users.one? { |u| u.admin? }).to eq true## # The same thing, but using the `be_one` matcher# expect(users).to be_one { |u| u.admin? }## # The same thing again, but using `satisfy_one` for improved readability# expect(users).to satisfy_one { |u| u.admin? }RSpec::Matchers.alias_matcher:satisfy_all,:be_allRSpec::Matchers.alias_matcher:satisfy_none,:be_noneRSpec::Matchers.alias_matcher:satisfy_one,:be_one
