列表中没有行分配给SObject测试类错误

Question

我是Apex新手需要Apex测试类的帮助。该控制器类的伟大工程，但我不能找到一种方法，将其复制到测试课，而不会出现错误“列表中包含了用于分配的sObject无行” 下面是实际的控制器类：

public with sharing class GoogleMap_Meeting_Controller { 

    public List<Meeting__c> MeetingsList {get;set;} 
    public List<Meeting__c> MeetingsList2 {get;set;} 

    public GoogleMap_Meeting_Controller() { 

     Id id = ApexPages.currentPage().getParameters().get('id'); 
     MeetingsList = [SELECT Id, Name, Group__r.Id, Meeting_Date__c, GPS_Meeting_Location__Latitude__s, GPS_Meeting_Location__Longitude__s FROM Meeting__c WHERE Group__r.Id =:id ORDER BY Meeting_Date__c DESC LIMIT 10 OFFSET 1]; 
     MeetingsList2 =[SELECT Id, Name, Group__r.Id, Meeting_Date__c, GPS_Meeting_Location__Latitude__s, GPS_Meeting_Location__Longitude__s FROM Meeting__c WHERE Group__r.Id =:id ORDER BY Meeting_Date__c DESC LIMIT 1]; 
    } // end constructor 
} // end class 

我的测试类;

public with sharing class GoogleMap_Meeting_Controller_Tester { 

    static testMethod void myTest() { 
     Meeting__c MeetingsList = new Meeting__c(); 
     Meeting__c MeetingsList2 = new Meeting__c(); 

     //Id id = ApexPages.currentPage().getParameters().get('id'); 
     MeetingsList = [SELECT Id, Name, Group__r.Id, Meeting_Date__c,  GPS_Meeting_Location__Latitude__s, GPS_Meeting_Location__Longitude__s FROM Meeting__c WHERE Group__r.Id ='a0Lc0000002zI9O' ORDER BY Meeting_Date__c DESC LIMIT 10 OFFSET 1]; 
     MeetingsList2 =[SELECT Id, Name, Group__r.Id, Meeting_Date__c, GPS_Meeting_Location__Latitude__s, GPS_Meeting_Location__Longitude__s FROM Meeting__c WHERE Group__r.Id ='a0Lc0000002zI9O' ORDER BY Meeting_Date__c DESC LIMIT 1]; 
    } // end constructor   
} // end class 

Answer 1

而不是

MeetingsList = [SELECT Id, Name, Group__r.Id, Meeting_Date__c, GPS_Meeting_Location__Latitude__s, GPS_Meeting_Location__Longitude__s FROM Meeting__c WHERE Group__r.Id =:id ORDER BY Meeting_Date__c DESC LIMIT 10 OFFSET 1]; 
MeetingsList2 =[SELECT Id, Name, Group__r.Id, Meeting_Date__c, GPS_Meeting_Location__Latitude__s, GPS_Meeting_Location__Longitude__s FROM Meeting__c WHERE Group__r.Id =:id ORDER BY Meeting_Date__c DESC LIMIT 1]; 

使用

List< MeetingsList> = [SELECT Id, Name, Group__r.Id, Meeting_Date__c, GPS_Meeting_Location__Latitude__s, GPS_Meeting_Location__Longitude__s FROM Meeting__c WHERE Group__r.Id =:id ORDER BY Meeting_Date__c DESC LIMIT 10 OFFSET 1]; 
List< MeetingsList2> =[SELECT Id, Name, Group__r.Id, Meeting_Date__c, GPS_Meeting_Location__Latitude__s, GPS_Meeting_Location__Longitude__s FROM Meeting__c WHERE Group__r.Id =:id ORDER BY Meeting_Date__c DESC LIMIT 1];
