試圖在JSON數組中使用期望js與Karma套件來聲明JSON對象的存在

你好，所以我正在爲我的redux異步動作編寫測試，並且我試圖斷言對象存在於objet數組中，但我無法獲得即使預期的副作用發生，測試也能成功運行（將數據保存到Firebase）試圖在JSON數組中使用期望js與Karma套件來聲明JSON對象的存在

這是我的測試。

describe('Async Actions',() => { 
     it('should upload supplier and dispatch ADD_SUPPLIER', (done)=> { /*Let Mocha know that this is asnyc test*/ 
      //mock a store 
      const store = createMockStore({}); 

      //test supplier 
      var testSupplier = { 
      name: "new supplier", 
      fact_sheet: "fact sheet", 
      liability_sheet: "liability sheet", 
      group: "group", 
      service_lines: null, 
      policies: null, 
      rate_periods: null, 
      rate_costs: null, 
      contracts: null, 
      cancellation_terms: null, 
      deposit_terms: null, 
      commission: 22, 
      creation_date: moment().unix(), 
      country: "SA", 
      region: "Capetown", 
      email: "[email protected]", 
      telephone: "2797179", 
      website: "ww.ww.ww", 
      category: "cat", 
      rating: 100 
      }; 

      //Do the async action 
      store.dispatch(actions.startAddSupplier(testSupplier.name, testSupplier.fact_sheet, testSupplier.liability_sheet, testSupplier.group, 
      testSupplier.commission, testSupplier.country, testSupplier.region, testSupplier.email, testSupplier.telephone, testSupplier.website, testSupplier.category, testSupplier.rating)).then(
       () => { 
        /*Assertions*/ 
      const actions = store.getActions(); //returns array of all actions fired on store 

      expect(actions).toInclude({ 
       type: 'ADD_SUPPLIER' 
      }); 


       /*done to show test is done*/ 
       done(); 
       }).catch(done);//if done is called with args it is assumed the test has failed 
     }); 
     });

，這就是我在控制檯中看到的錯誤

      at eval (eval at <anonymous> (/Users/zacck/Documents/www/jtx/app/tests/actions/actions.test.jsx:47:2), <anonymous>:129:42)

我敢肯定，我做錯了什麼我想任何感謝所有幫助找到錯誤。

您的測試'testSupplier'沒有'id'屬性。 –

嗯，所以這裏的問題似乎是你對單元測試的理解，你在這裏測試的代碼會向firebase實例分派一個異步方法。建議使用來自Firebase實例的模擬響應運行測試，這將允許您聲明代碼正確響應來自Firebase的成功響應和失敗響應，從而照顧不愉快的路徑。在這裏看到這篇文章 https://robots.thoughtbot.com/how-to-stub-external-services-in-tests
