is this kosher?

rr_kosher.rb

describe "thing" do
  before do
    @obj_1 = Object.new
    @obj_2 = Object.new
    stub(@obj_1).foo { puts "stubbed foo (1)" }
    stub(@obj_2).foo { puts "stubbed foo (2)" }
  end

  it "1 does things" do
    mock(@obj_1).foo { puts "mocked foo (1)" }

    @obj_1.foo
    @obj_2.foo
  end

  it "2 does things" do
    mock(@obj_2).foo { puts "mocked foo (2)" }

    @obj_1.foo
    @obj_2.foo
  end
end
