Salesforce中的触发器测试类

Question

大家好，

我正在尝试为我帮助编写的触发器编写一个测试类。触发器使用名为trigger\u help\u c的字段，该字段是通过添加opportunity Type和Account ID派生的公式字段，如果在过去90天内已在该帐户上创建了该类型的opportunity，则在插入之前激发。除非配置文件是系统管理员。这是我的触发器：

trigger leadDuplicatePreventer on opportunity(before insert) {
   set<string> settgs = new set<string>();
   list<opportunity> opps = [select id,Trigger_Help__c  from opportunity WHERE CreatedDate = LAST_N_DAYS:90];
   Profile p=[SELECT ID, Name FROM Profile WHERE Id=:userinfo.getProfileId() Limit 1];
   for(opportunity opp : opps){
     if(opp.Trigger_Help__c != null && p.Name <> 'System Administrator'){
	 settgs.add(opp.Trigger_Help__c);
	 }
   }
   
   for(opportunity op : trigger.new){
      if(settgs.contains(op.Trigger_Help__c)){
	     op.adderror('An Opportunity of this type already exists on this Account.  Please contact a system administrator with questions.');
	  }
   
   }


   
}​

我在写测试课时遇到了困难，我像往常一样不知所措。我写了以下内容，但我不知道我真正需要做什么：

@isTest
private class TestleadDuplicatePreventer {
    @isTest static void TestleadDuplicatePreventerwithOneOpp() {
        Account acct = new Account(Name='Test Account');
        insert acct;
        Opportunity opp = new Opportunity(Name=acct.Name + ' Opportunity',
                                         StageName='Open Opportunity',
                                         CloseDate=System.today().addMonths(1),
                                         Facility__c='Tacoma WA',
                                         Oppty_Type__c='UCO Service',
                                         AccountID=acct.Id);
        insert opp;
        Test.startTest();
        opp= new Opportunity(Name='Opportunity Test',
                            StageName='Open Opportunity',
                            CloseDate=System.today().addMonths(2),
                            Facility__c='Tacoma WA',
                            Oppty_Type__c='UCO Service',
                            Account=[SELECT ID from Account WHERE Account.Name='Test Account']);
        try
        {
            insert opp;
        }
        catch(Exception duplicate)
        {       
        }
        Test.stopTest();
    }

}​

非常感谢您的帮助！！

不确定您对项目的确切要求是什么，您可能无需代码执行汇总和字段即可完成此操作，该字段计算与具有Trigger_Help__c中使用的类型的帐户相关联的机会，然后对机会进行验证，当ISnew（）如果帐户。Count_Of_Type__c

但对于您最初的问题：在您的测试中，我看不到您设置了Trigger\u Help\u c字段，除非它是由自动化设置的。此外，在创建第二个opp时，您不需要查询帐户，只需使用代码前面的帐户Id即可。

对于捕获，您需要断言e.getMessage（）是您期望从触发器中的添加错误中得到的消息。

您可能还需要执行一个单独的操作，其中您以管理员身份运行（admin\u user），其中admin\u user是您使用系统管理员配置文件创建的用户，以确保您在以管理员身份运行时不会出错，具体操作如下：

@isTest
private class TestleadDuplicatePreventer {
    @isTest static void TestleadDuplicatePreventerwithOneOpp() {
    Account acct = new Account(Name='Test Account');
    insert acct;
    Opportunity opp = new Opportunity(Name=acct.Name + ' Opportunity',
                                     StageName='Open Opportunity',
                                     CloseDate=System.today().addMonths(1),
                                     Facility__c='Tacoma WA',
                                     Oppty_Type__c='UCO Service',
                                     AccountID=acct.Id);
    insert opp;
    Test.startTest();
    opp= new Opportunity(Name='Opportunity Test',
                        StageName='Open Opportunity',
                        CloseDate=System.today().addMonths(2),
                        Facility__c='Tacoma WA',
                        Oppty_Type__c='UCO Service',
                        AccountId=acct.Id);
    try
    {
        insert opp;
    }
    catch(Exception duplicate)
    {       
       System.assertEquals('An Opportunity of this type already exists on this Account.  Please contact a system administrator with questions.', duplicate.getMessage())
    }
    //this should probably be in a separate test method
    Profile p = [SELECT Id FROM Profile WHERE Name='System Administrator'];
  User u2 = new User(Alias = 'newUser', Email='[e-mail]',
     EmailEncodingKey='UTF-8', LastName='Testing', LanguageLocaleKey='en_US',
     LocaleSidKey='en_US', ProfileId = p.Id,
     TimeZoneSidKey='America/Los_Angeles', UserName='[e-mail]');

  System.runAs(u2) {
      insert opp;
  }
    Test.stopTest();
}

}
