Triggers 插入前/更新前Apex触发器上的测试覆盖率失败

我有一个非常简单的Prefore insert/update触发器on Opportunity，它根据包含销售办事处（州）位置信息的下拉值自动选择价目表

这是我的触发器：

trigger SelectPriceBook on Opportunity ( before insert, before update ) {

    for( Opportunity opp : Trigger.new ) {
        // Change Price Book
        // New York
        if( opp.Campus__c == 'NYC' )
          opp.Pricebook2Id = PB_NYC; // contains a Pricebook's ID

        // Atlanta
        if( opp.Campus__c == 'ATL' )
          opp.Pricebook2Id = PB_ATL; // contains another Pricebook's ID
    }
}

@isTest (SeeAllData = true)
public class SelectPriceBookTestClass {

    static testMethod void validateSelectPriceBook() {

        // Pricebook IDs
        ID PB_NYC =  'xxxx';
        ID PB_ATL =  'xxxx';

        // New Opp
        Opportunity opp = new Opportunity();
        opp.Name = 'Test Opp';
        opp.Office__c = 'NYC';
        opp.StageName = 'Quote';       

        // Insert
        insert opp;

        // Retrive inserted opportunity
        opp = [SELECT Pricebook2id FROM Opportunity WHERE Id =:opp.Id];
        System.debug( 'Retrieved Pricebook Id: ' + opp.Pricebook2Id );

        // Change Campus
        opp.Office__c = 'ATL';
        // Update Opportunity
        update opp;

        // Retrive updated opportunity
        opp = [SELECT Pricebook2id FROM Opportunity WHERE Id =:opp.Id];
        System.debug( 'Retrieved Updated Pricebook Id: ' + opp.Pricebook2Id );        

        // Test
        System.assertEquals( PB_ATL, opp.Pricebook2Id );

    }
}

这是我的测试课：

trigger SelectPriceBook on Opportunity ( before insert, before update ) {

    for( Opportunity opp : Trigger.new ) {
        // Change Price Book
        // New York
        if( opp.Campus__c == 'NYC' )
          opp.Pricebook2Id = PB_NYC; // contains a Pricebook's ID

        // Atlanta
        if( opp.Campus__c == 'ATL' )
          opp.Pricebook2Id = PB_ATL; // contains another Pricebook's ID
    }
}

@isTest (SeeAllData = true)
public class SelectPriceBookTestClass {

    static testMethod void validateSelectPriceBook() {

        // Pricebook IDs
        ID PB_NYC =  'xxxx';
        ID PB_ATL =  'xxxx';

        // New Opp
        Opportunity opp = new Opportunity();
        opp.Name = 'Test Opp';
        opp.Office__c = 'NYC';
        opp.StageName = 'Quote';       

        // Insert
        insert opp;

        // Retrive inserted opportunity
        opp = [SELECT Pricebook2id FROM Opportunity WHERE Id =:opp.Id];
        System.debug( 'Retrieved Pricebook Id: ' + opp.Pricebook2Id );

        // Change Campus
        opp.Office__c = 'ATL';
        // Update Opportunity
        update opp;

        // Retrive updated opportunity
        opp = [SELECT Pricebook2id FROM Opportunity WHERE Id =:opp.Id];
        System.debug( 'Retrieved Updated Pricebook Id: ' + opp.Pricebook2Id );        

        // Test
        System.assertEquals( PB_ATL, opp.Pricebook2Id );

    }
}

测试运行报告0%测试覆盖率

同样，在类似的行中，我有另一个before insert触发器，它将事件的所有者设置为与父潜在客户的所有者相同。代码如下：

trigger AutoCampusTourOwner on Event( before insert ) {

    for( Event evt : Trigger.new ) {
        // Abort if other kind of Event
        if( evt.Subject != 'Visit' )
            return;        

        // Set Owner Id
        Lead parentLead = [SELECT OwnerId FROM Lead WHERE Id = :evt.WhoId];
        evt.OwnerId = parentLead.OwnerId;

    }
}

这也导致了0%的覆盖率——我猜这与这两个循环中的for循环有关。我知道我在for循环中调用SOQL查询是在严重藐视DML规则，但出于我的目的，这应该是好的，因为这些事件是手动创建的，并且一次只创建一个，所以不会因为批量插入而影响调控器限制的范围

这两种情况下的代码都能100%工作。请建议对测试用例进行修复

你试过扳机吗？？我的想法是，当您将测试类中的office从NYC更新为ATL时，值'NYC'将位于trigger.old中，这就是您要在触发器中检查的内容。

我可能是错的，因为我也是apex的新手，但是尝试一下，让我知道会发生什么。

对于第一个触发器，不要做任何事情，只是创造机会并像这样执行

SelectPriceBook的测试类

@isTest
    private class TriggerTestClass {

        static testmethod void selectPriceTest(){
            Opportunity opps = new Opportunity(
                Name= 'Test Opps',
                CloseDate = System.today().addDays(30),
                StageName = 'Prospecting', 
                ForecastCategoryName = 'Pipeline',
                Office__c = 'NYC');
                insert opps;

                Opportunity opps2 = new Opportunity(
                Name= 'Test Opps 2',
                CloseDate = System.today().addDays(28),
                StageName = 'Prospecting', 
                ForecastCategoryName = 'Pipeline',
                Office__c = 'ATL');
                insert opps2;
        }

    }

它会给你很好的测试覆盖率，我不知道你想在AutoCumpstourowner做什么

我有这方面的测试课程

在Infloones\uuuu客户端\uu电子邮件\uuuuu c上触发ClientEmailTrigger（插入后、更新后、插入前、更新前）{

}

在第一种情况下，您的触发器正在查看校园，但您的测试正在设置office__c@superfell对不起，这是个打字错误。但代码仍然失败。有什么建议吗？
