+Feature: Shared example group
+
+  As an RSpec user
+  I want to share my examples
+  In order to reduce duplication in my specs
+
+  Scenario: Using a shared example group
+    Given a file named "shared_example_group_spec.rb" with:
+    """
+    require "set"
+
+    shared_examples_for "a collection object" do
+      before(:each) do
+        @instance = described_class.new([7, 2, 4])
+      end
+
+      it "should have 3 items" do
+        @instance.size.should == 3
+      end
+
+      it "should return the first item from #first" do
+        @instance.first.should == 7
+      end
+    end
+
+    describe Array do
+      it_should_behave_like "a collection object"
+    end
+
+    describe Set do
+      it_should_behave_like "a collection object"
+    end
+    """
+    When I run "rspec ./shared_example_group_spec.rb"
+    Then the output should contain "4 examples, 0 failures"
