spec/support/matchers/satisfy_matchers.rb

+# 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? }
