+Feature: render_template matcher
+
+  This matcher just delegates to the Rails assertion method
+  "assert_template". For complete info on the available options,
+  please take a look at the Rails documentation.
+
+  This method is available in spec/controllers and spec/requests.
+
+  Scenario: render_template with three possible options
+    Given a file named "spec/controllers/gadgets_spec.rb" with:
+      """
+      require "spec_helper"
+
+      describe GadgetsController do
+        describe "#index" do
+          subject { get :index }
+
+          specify { should render_template(:index) }
+          specify { should render_template("index") }
+          specify { should render_template("gadgets/index") }
+        end
+      end
+      """
+    When I run "rspec spec/controllers/gadgets_spec.rb"
+    Then the output should contain "3 examples, 0 failures"
