Question

我在71％，由于某种原因，4行代码无法在测试中运行。当我在Salesforce中测试自己时，它可以运行（这些代码行正在运行）。如何才能在测试中运行这些代码？

行没有运行，在第二个for循环中 nextId = Integer.Valueof（c.next_id__c）;
行没有运行，在第三个for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

尽管使用seeAllData = true可以提高测试覆盖率，但是除非确实需要，否则最好不要使用seeAllData。有关详细信息，请参阅博客here。

增加覆盖率的另一种方法是为tracking_next_id__c对象创建测试数据。

    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;

我已添加以下行，以便在FOR循环之前执行2个查询（以前未涵盖）时，它将获取数据，因为我们现在已将它插入测试类中。

$html1 = file_get_html("https://www.amazon.com" .
    "/Tom-Clancys-Division-Xbox-One/dp/B00DDXILBQ/" .
    "ref=sr_1_1?ie=UTF8&qid=1487430751&sr=8-1&keywords=Tom%2BClancy%27s%2BThe%2BDivision&th=1");
$title1 = $html1 - > find("div.sims-fbt-rows,0") - > find("span.p13n-sc-price") - > innertext;
if ($title1) {
    echo $title1;
} else {
    echo 'problem';
}

只是观察一下，最好避免FOR循环中的SOQL查询以避免运行时异常（ 101：SOQL查询太多）

 @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）并将其移至100％ https://developer.salesforce.com/forums/ForumsMain?id=9060G000000I5f8
