Question

我正在尝试将模拟JSON数据传递给我的jasmine单元测试。

我的JSON格式与下面的格式类似

Array.prototype.choice = function(){
    return this[~~(Math.random()*this.length)];
};

// now you can call it like this :)
console.log( ["0", "911"].choice() );

我使用上面的JSON传递给类似下面的单元测试函数

{   
   "CompanyResponse":{    
      "CompanyCreatedDate":"1990-10-02",    
      "RunDate":"2",   
      "LastChangedDate":"2015-10-02",   
      "CompanySummary": {   
         "Id":"Apple",   
         "MaximumCredit":"10000000",   
         "Margin":"60000000",    
         "Limit":"-1500000",    
         "HistoricData":{    
            "CompanyHistoricData": [   
               {  
                  "LaunchDate":"2008-08-31",  
                  "Product":"Iphone2",  
                  "TotalProductsCreated":"1000000",  
                  "TotalProductsSold":"800000",  
                  "TotalReturns":"200000",  
                  "TotalMargin":"600000"  
               },  
               {  
                  "LaunchDate":"2010-08-31",  
                  "Product":"Iphone4",  
                  "TotalProductsCreated":"2000000",  
                  "TotalProductsSold":"1500000",  
                  "TotalReturns":"350000",  
                  "TotalMargin":"800000"  
               }  
            ]  
         },  
         "RefurbishedData": {  
            "CompanyRefurbished": [  
               {  
                  "Id":"Apple.201221.12",  
                  "ProductId":"iph-213454",  
                  "StartDate":"2015-09-07",  
                  "FinishDate":"2015-09-10",  
                  "CostOfRefurbishing":"50"  
               },  
               {  
                  "Id":"Apple.201228.12",  
                  "ProductId":"iph-4155655",  
                  "StartDate":"2015-09-10",    
                  "FinishDate":"2015-09-12",  
                  "CostOfRefurbishing":"85"  
               }  
            ]  
         }  
      }  
   }  
}

}

我面临的问题是，我无法将CompanyResponse作为一个整体传递给getTotal（）函数，即使我执行JSON.stringify（）也无法工作 - 因为它只是将它转换为字符串，如果我执行JSON.parse（），它将无效，因为它将它转换回Object格式。

请提供相同的观点。

下面列出了我们如何在正常场景中调用getTotal（）方法

public getTotal(response: CompanyResponse): void {    
  var companySummary = response.CompanySummary;    

  //gets total 'CostOfRefurbishing' for all phones    
  var totalRefurbishmentAmount :number = 0;

  for (let companyRefurbishments of companySummary.RefurbishedData) {
    totalRefurbishmentAmount += Number.parseInt(companyRefurbishments.CostOfRefurbishing.toString());
  }

干杯，大师

您可以使用standard Response Interface from the JavaScript Fetch API来模拟响应对象吗？

如果查看documentation for the constructor method，则会接受body参数和init选项对象。 body参数可以是Blob，因此您可以;

var data = {foo: "bar"};
var blob = new Blob([JSON.stringify(data, null, 2)], {type : 'application/json'});

var init = { "status" : 200 , "statusText" : "SuperSmashingGreat!" };
var myResponse = new Response(blob, init);

这将创建一个Response对象，您应该能够将其传递给测试。

将JSON对象转换为响应对象
