shared_context はその名前の通りコンテキスト (テストを行なうときの状況) を共有するための機能です。
shared_context を使うことで複数箇所にちらばる同一処理をまとめることができます。shared_context は shared_context が書かれたファイルを require することでも使えるようになるので別のスペックファイルでも使うことができます。

	shared_context "shared stuff" do
	before { @some_var = :some_value }
	def shared_method
	"it works"
	end
	let(:shared_let) { {'arbitrary' => 'object'} }
	subject do
	'this is the subject'
	end
	end

	describe "group that includes a shared context using 'include_context'" do
	include_context "shared stuff"

	it "has access to methods defined in shared context" do
	shared_method.should eq("it works")
	end

	it "has access to methods defined with let in shared context" do
	shared_let['arbitrary'].should eq('object')
	end

	it "runs the before hooks defined in the shared context" do
	@some_var.should be(:some_value)
	end

	it "accesses the subject defined in the shared context" do
	subject.should eq('this is the subject')
