ruby-on-rails - Rails - redirect_to(request.referer) 的功能测试

Question

也许我再次只见树木不见森林，但我似乎无法找到一种方法来编写功能测试来测试重定向到 request.referer 的 :destroy 操作。

代码是:

  def destroy
    @step = Step.find(params[:id])
    @step.destroy

    respond_to do |format|
      format.html { redirect_to(request.referer) }
      format.xml  { head :ok }
    end
  end

失败的测试是:

  test "should destroy step" do
    assert_difference('Step.count', -1) do
      delete :destroy, :id => @step.to_param
    end
    assert_redirected_to request.referer
  end

没有运气使用:

redirect_to(:back)

...还有。

明白了。

通过测试是:

  test "should destroy step" do
    assert_difference('Step.count', -1) do
      @request.env['HTTP_REFERER'] = 'http://test.com/steps/1'
      delete :destroy, :id => @step.to_param
    end
    assert_redirected_to @request.env['HTTP_REFERER']
  end
