Salesforce如何达到75％的顶点测试

Question

我以71％的速度为71％，由于某些原因，在测试中无法运行4行代码。当我在Salesforce中测试自己时，它可以正常运行（这些代码行正在运行）。如何在测试中获得这些代码行？

1. 线不运行，以循环为名 nextID = integer.valueof（c.next_id__c）;

2. 线未运行，在第三次循环中 btnrecord.next_id__c = newid 1; btnrecord.last_id__c = newid;

       btnRecord.last_assigned_starting_id__c = nextId;
       btnRecord.last_assigned_ending_id__c = newId;
   

以下是我的代码：

trigger getNextId on tracking__c (before insert, before update) {
Integer newId;
Integer lastId;
Integer nextId;
newId=0;
lastId=0;
nextId =0;

//add the total accounts to the last_id
for (tracking__c bt: Trigger.new) {
    //get the next id
    List<tracking_next_id__c> btnxtid = [SELECT  next_id__c FROM tracking_next_id__c];
    for (tracking_next_id__c c : btnxtid )
    {
       nextId=Integer.Valueof(c.next_id__c);
    }

    newId = Integer.Valueof(bt.total_account__c) + nextId;
    bt.starting_id__c = nextId;
    bt.ending_id__c = newId;
    tracking_next_id__c[] nextIdToUpdate = [SELECT last_id__c, next_id__c, last_assigned_starting_id__c, last_assigned_ending_id__c FROM tracking_next_id__c];
    for(tracking_next_id__c btnRecord : nextIdToUpdate ){
        btnRecord.next_id__c = newid + 1;
        btnRecord.last_id__c = newId;
        btnRecord.last_assigned_starting_id__c = nextId;
        btnRecord.last_assigned_ending_id__c = newId;
    }
    update nextIdToUpdate ;
   }
   }

Answer 1

即使使用seealldata = true增加了测试覆盖范围，但除非并且直到真正需要之前，否则使用seealldata是最好的做法。请在此处找到博客以获取详细信息。

增加覆盖范围的另一种方法是为tracking_next_id__c对象创建测试数据。

    @isTest
    private class getNextIdTest {
    static testMethod void validateOnInsert(){
        tracking_next_id__c c = new tracking_next_id__c(next_id__c='Your next_id', 
                last_id__c='Your last_id', last_assigned_starting_id__c='Your last_assigned_starting_id', 
                last_assigned_ending_id__c='last_assigned_ending_id');
        insert c;
        tracking__c b = new tracking__c(total_account__c=Integer.Valueof(99));
        System.debug('before insert : ' + b.total_account__c);
        insert b;
        System.debug('after insert : ' + b.total_account__c);
        List<tracking__c> customObjectList =
        [SELECT total_account__c FROM tracking__c ];
        for(bid_tracking__c ont : customObjectList){
            ont.total_account__c = 5;
        }
        update customObjectList;
    }
}

我添加了下面的行，因此，当循环之前执行2个查询（）之前 ），它将在我们现在插入测试类时获取数据。

    tracking_next_id__c c = new tracking_next_id__c(next_id__c='Your next_id', 
            last_id__c='Your last_id', last_assigned_starting_id__c='Your last_assigned_starting_id', 
            last_assigned_ending_id__c='last_assigned_ending_id');
    insert c;

只是一个观察，最好避免soql查询以避免运行时异常（ 101：太多SOQL查询）

 @isTest
private class getNextIdTest {
        static testMethod void validateOnInsert(){
        tracking__c b = new tracking__c(total_account__c=Integer.Valueof(99));
        System.debug('before insert : ' + b.total_account__c);
    insert b;
    System.debug('after insert : ' + b.total_account__c);
    List<tracking__c> customObjectList =
 [SELECT total_account__c FROM tracking__c ];
    for(bid_tracking__c ont : customObjectList){
    ont.total_account__c = 5;
    }
    update customObjectList;
    }
    }

添加@istest（seealldata = true），然后移动到100％ https://developer.salesforce.com/forums/forumsmain?id=9060g00000000i5f8
