在 Salesforce 中测试 Class 的触发器

Test Class in Salesforce for a Trigger

大家好,

我正在尝试为我帮助编写的触发器编写测试 class。触发器使用一个名为 trigger_help__c 的字段,这是一个从添加机会类型和帐户 ID 派生的公式字段,如果在过去 90 天内在该帐户上创建了该类型的机会,则触发器会在插入之前触发。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.');
   }
   
   }


   
}​

我在编写测试时遇到了问题 class,而且我一如既往地一无所知。我写了以下内容,但我不知道我实际需要做什么:

@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();
    }

}​

感谢任何帮助!!

不确定您对项目的确切要求,您可能无需代码就可以完成此操作,而无需执行汇总总和字段,该字段计算与 [= 中使用的类型的帐户相关的机会34=] 然后验证当 ISNEW() if Account.Count_Of_Type__c > 0 导致触发验证或机会创建一个隐藏字段,该字段是唯一的,它是帐户 ID 和机会类型的串联,可以由工作流或流程构建器设置。这将防止为给定帐户添加重复类型。

但对于您最初的问题:在您的测试中,我没有看到您设置了 Trigger_Help__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 acct.Id

对于您的捕获,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。

您可能还需要单独执行 运行As(admin_user) 操作,其中 admin_user 是您使用系统管理员配置文件创建的用户,以确保您不会当您 运行 作为管理员用户时出现错误,如下所示:

@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='newuser@testorg.com',
     EmailEncodingKey='UTF-8', LastName='Testing', LanguageLocaleKey='en_US',
     LocaleSidKey='en_US', ProfileId = p.Id,
     TimeZoneSidKey='America/Los_Angeles', UserName='newuser@testorg.com');

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