#describe(*args, &example_group_block) ⇒ Object Also known as: context

Makes the describe/it syntax available from a class. For example:

class StackSpec < Spec::ExampleGroup
  describe Stack, "with no elements"

  before
    @stack = Stack.new
  end

  it "should raise on pop" do
    lambda{ @stack.pop }.should raise_error
  end
end
