在为这个将记录货币转换为组织货币的触发器编写测试类时，我几乎不需要任何帮助。有人可以帮忙/指导吗？请。

trigger convertToEuro on CustomObject(before update) { 

List<CurrencyType> currencyTypeList = [select id,IsoCode,ConversionRate from CurrencyType where isActive = true] ;

Map<String , Decimal> isoWithRateMap = new Map<String, Decimal>();

for(CurrencyType c : currencyTypeList) {

    isoWithRateMap.put(c.IsoCode , c.ConversionRate) ;

}

for(CustomObject ce: trigger.new){

    if(ce.CurrencyIsoCode != 'EUR' && isoWithRateMap.containsKey(ce.CurrencyIsoCode)){

        ce.Amount_Converted__c = ce.ffps_iv__Amount__c/ isoWithRateMap.get(ce.CurrencyIsoCode);

    }

}

}

           liCustomObjectsToUpdate.add(co);
       }
       test.startTest();
       Update liCustomObjectsToUpdate;
       test.stopTest();
       System.assertEquals([SELECT Id, Amount_Converted__c FROM CustomObject LIMIT 1][0].Amount_Converted__c, 1);
   }
}

如果不添加您的自定义对象，我无法测试此代码，因此它可能会出现一些错误。请让我知道您遇到了什么错误。如果您需要帮助调试，您应该提供正在使用的确切代码和确切的错误消息。

它遵循测试更新触发器的基本模式：

  1. 插入测试数据
  2. 检索测试数据
  3. 更新记录
  4. 断言触发器生成了所需的结果
