-  it "should have one manager" do
-    pending("create managers resource")

-  it "should validate associated manager" do
-    pending("create managers resource")

 Create a new matcher is easy. Let's create validate_inclusion_of matcher for

 module Remarkable
-  module ActiveRecord
+  module ActiveModel
     module Matchers
-      class ValidateInclusionOfMatcher < Remarkable::ActiveRecord::Base
+      class ValidateInclusionOfMatcher < Remarkable::ActiveModel::Base

         assertion :is_valid?

 As you noticed, the matcher doesn't have any message on it. You add them on I18n
 file. A file for this example would be:
