如何在 RSPEC 中设置语言环境

Question

我是 RSPEC 的新手。我编写了一个名为 result_spec.rb 的 RSPEC 代码，如下所示：

describe '#grouped_scores' do
subject { result.grouped_scores }

let(:result) { create(:result, user: user) }

its(:keys) { is_expected.to eq [1] }
its([1]) { is_expected.to be_within(0.001).of(6) }
end

然后当我在名为result.rb的模型中编写方法时，示例代码如下：

def grouped_scores
  s = 0
  if score > 10 && I18n.locale == :zh then
    s = 2
  end
  return s
end

但是，当我在本地测试 RSPEC 时，我不断收到以下错误：

Failures:
1) Result#grouped_scores keys should eq [1]
 Failure/Error: its(:keys) { is_expected.to eq [1] }

   expected: [1]
        got: []

   (compared using ==)
 # ./spec/models/result_spec.rb:39:in `block (3 levels) in <top (required)>'
2) Result#grouped_personality_scores [1] should be within 0.001 of 6
 Failure/Error: its([1]) { is_expected.to be_within(0.001).of(6) }
   expected 0 to be within 0.001 of 6
 # ./spec/models/result_spec.rb:40:in `block (3 levels) in <top (required)>'

所以我想知道，是不是因为我没有将 I18n.locale 设置为“zh”，因此它没有得到值？如果是这样，如何在 RSPEC 中分配语言环境？或者还有什么我应该知道的来调试 RSPEC 中的错误？

请帮忙！谢谢！！

测试语言环境

# Assuming I have a LocalesController with check_for_locale action
describe LocalesController do

  after(:each) do
    I18n.locale = :en
  end

  it "should check if the locale is zh" do
    get :check_for_locale, locale: :zh
    expect(I18n.locale).to eq(:zh)
  end

  it "should check if the locale is set to default that is english" do
    get :check_for_locale
    expect(I18n.locale).to eq(:en)
  end

end

locales_controller.rb

class LocalesController < ApplicationController

  def check_for_locale

  end

end
