Question

我正在尝试制作rspec测试用例。但是，Rspec因为Name已经失败了。

似乎每次“产品”调用时都会“评估”。

我该如何解决？

product_decorator_spec.rb

require 'spec_helper'

describe Spree::Product do

  context '#create' do
    let(:us) { create(:zone, name: "US") }
    let(:china) { create(:zone, name: "China") }
    let(:japan) { create(:zone, name: "Japan") }


    context "when a product has no ng zone" do
      let(:product) { create(:product, zones: [us, china, japan]) }

      it "should get ng_zones correctly" do
        product.ng_zones.should match_array []
      end
    end

    context "when a product has one ng zone" do
      let(:product) { create(:product, zones: [us, china]) }

      it "should get ng_zones correctly" do
        product.ng_zones.should match_array ["Japan"]
      end
    end

    context "when a product has two ng zone" do
      let(:product) { create(:product, zones: [us]) }

      it "should get ng_zones correctly" do
        product.ng_zones.should match_array ["China", "Japan"]
      end
    end
  end
end

Answer 1

使用每个let块评估it的正文。我假设你的Zone类有唯一性约束。

你有两种可能性

在before(:all)块中构建变量并将其分配给@us
清理数据库after(:each)

Answer 2

您正在测试Product#create，因此，您不需要为此特定测试真正创建zones。

相反，您可以使用build_stubbed方法。

let(:us) { build_stubbed(:zone, name: "US") }
let(:china) { build_stubbed(:zone, name: "China") }
let(:japan) { build_stubbed(:zone, name: "Japan") }

这样，它的创建过程不依赖于数据库以及Zone模型的验证，并且你有一个很棒的性能提升，因为你没有为每个数据库命中数据库单一测试。

您可以阅读build_stubbed here。

如果它以某种方式帮助你，请告诉我。 ;）

Rspec因为名字已经失败而失败
