Here is the test class:

    FlowstoUser BatchClass = new FlowstoUser();
    Database.executeBatch(BatchClass, 1);

 The part where I declare haum is the offending line of code. I would appreciate any help.

Presumeably the only part of this code that matters is the test class at the very bottom.

That's the error I'm getting from the test in this class:

 (Code removed)

I'm obviously doing something wrong with this test class but I can't figure out what. Can anyone help me?

I've put together a trigger to roll up some asset amounts from contacts to our accounts, however, I can't figure out for the life of me how I would write a test class in this situation, can anyone help me? I'm no apex pro.

Also- the fields being summed and sent to the account object are actually rollup fields from a child object of contact. When these fields are updated will they cause the trigger to fire? There's one of these triggers for each of our different asset amounts (8 in total).

Thanks for your help!

trigger SumBalanced on Contact (after insert,after update,after delete)
{
    Set<Id> accountIdset = new Set<Id>();
   
    for (Contact con:trigger.new)
    {
       accountIdset.add(con.AccountId);
    }
    Map<Id,Account> AccountMap = new Map<Id,Account>([Select Id,Balanced__c from Account where Id in :accountIdset]);
    for(AggregateResult res : [SELECT AccountId, SUM(Balanced__c) cnt FROM Contact where AccountId in : accountIdset GROUP BY ROLLUP(AccountId)]){
        if(res.get('AccountId') <> null){
            AccountMap.get((ID)res.get('AccountId')).Balanced__c = (Decimal)res.get('cnt');
        }
    }
    update AccountMap.values();
	}

Here is the test class:

@isTest
public static void testBatch() {

Profile p = [SELECT Id FROM Profile WHERE Name='Standard User']; 

User u2 = new User(Alias = 'standt', Email='standarduser@testorg.com', 
      EmailEncodingKey='UTF-8', LastName='Testing', LanguageLocaleKey='en_US', 
      LocaleSidKey='en_US', ProfileId = p.Id, 
      TimeZoneSidKey='America/Los_Angeles', UserName='standarduser@testorg.com');
    insert u2;

 
 Account a = new Account(Name = 'Test Account', ShippingPostalCode = '00000', BillingCountry = 'US', OwnerID= u2.Id, Inflows__c = 100, Outflows__c= 100, navmfv2__AUM_as_of__c = Date.today());
    insert a;

    Test.StartTest();
    FlowstoUser BatchClass = new FlowstoUser();
    Database.executeBatch(BatchClass, 1);
    Test.StopTest();
  }

Hi all,

Still new to Apex and am having trouble with this test class:

@isTest

public class emailHandlerTest {

static testMethod void emailTest() {

//Create fake records
RecordType rt = [SELECT Id FROM RecordType WHERE SobjectType = 'Account' AND isActive = true AND DeveloperName like '%Person_Account%' LIMIT 1];
Account a = new Account();
a.RecordTypeId = rt.Id;
a.LastName = 'test';
insert a;

Property__c prop = new Property__c();
prop.Address_Line_1__c = '123 Street';
prop.Name = '123 Street';
insert prop;

rt = [SELECT Id FROM RecordType WHERE SobjectType = 'Opportunity' AND isActive = true AND Name like '%Rental%' LIMIT 1];
Opportunity opp = new Opportunity();
opp.AccountId = a.Id;
opp.Name = 'test';
opp.StageName = 'test';
opp.CloseDate = system.today();
opp.RecordTypeId = rt.Id;
opp.Property__c = prop.Id;
insert opp;

rt = [SELECT Id FROM RecordType WHERE SobjectType = 'Applicants__c' AND isActive = true AND Name like '%Primary_Applicant%' LIMIT 1];
Applicants__c app = new Applicants__c();
app.RecordTypeId = rt.Id;
app.Opportunity_Name__c = opp.Id;
app.Property__c = prop.Id;
app.Applicant_Email__c = 'test@test.com';

//Initiate Test One - Will the first email field fill in after an applicant record is inserted?
Test.startTest();

insert app;

Test.stopTest();

system.assert(opp.Additional_Applicant_1__c == 'test@test.com'); //This is Line 43
}
}

Actual Trigger being tested is here:

trigger emailHandler on Applicants__c (after insert) {

Set<ID> opportunityIds = new Set<ID>();

for (Applicants__c a: trigger.new) {

opportunityIds.add(a.Opportunity_Name__c);
}

List<Applicants__c> applicantEmail = [Select id, Applicant_Email__c From Applicants__c Where id in: Trigger.new];

List<Opportunity> emailFields = [Select id, Additional_Applicant_1__c, Additional_Applicant_2__c,Additional_Applicant_3__c,Additional_Applicant_4__c
From Opportunity
Where id in: opportunityIds];

for (Opportunity o: emailFields) {

for (Applicants__c a: applicantEmail) {

String email = a.Applicant_Email__c;

if (o.Additional_Applicant_1__c == null) {

o.Additional_Applicant_1__c = email;

}Else if (o.Additional_Applicant_1__c <> null && o.Additional_Applicant_2__c == null) {

o.Additional_Applicant_2__c = email;

}Else if (o.Additional_Applicant_1__c <> null && o.Additional_Applicant_2__c <> null && o.Additional_Applicant_3__c == null) {

o.Additional_Applicant_3__c = email;

}Else if (o.Additional_Applicant_1__c <> null && o.Additional_Applicant_2__c <> null && o.Additional_Applicant_3__c <> null && o.Additional_Applicant_4__c == null) {

o.Additional_Applicant_4__c = email;
}
}
}

update emailFields;
}

As you can see I'm creating fake records so that I can fulfill the required fields on my Applicant__c object.  I have to have an account to create the property, a property to create the opportunity, etc.  

The trigger I'm testing is "after insert" so that's why I'm putting the "insert app" line in within the test; because I want to see what happens to the opportunity after an applicant record is inserted.  What should happen is that "test@test.com" gets put in an opportunity field called "Additional_Applicant_1__c".

I'm using the Developer Console and there are no errors to solve.  I run the test and get "Assertion Failed" at line 43, which I take to mean that "test@test.com" is NOT present on that field.

The trouble is that an actual test of this code works perfectly (meaning if I physically create the applicant record instead of using the test class).

Bottom Line: I know the code works, but I can't get the test class to prove it.  Please help!

Here's the trigger:

trigger HistoricalAUM on Account (after insert, before update) {

List<Historical_AUM__c> TransferAUM = new List <Historical_AUM__c> {};

 Account[] accts;
    if (Trigger.isDelete) 
        accts = Trigger.old;
    else
        accts = Trigger.new;

}
try {
upsert TransferAUM UpsertID__c;
}
catch (Exception Ex)
{
system.debug(Ex);

 The part where I declare haum is the offending line of code. I would appreciate any help.

Presumeably the only part of this code that matters is the test class at the very bottom.

That's the error I'm getting from the test in this class:

 (Code removed)

I'm obviously doing something wrong with this test class but I can't figure out what. Can anyone help me?

I've put together a trigger to roll up some asset amounts from contacts to our accounts, however, I can't figure out for the life of me how I would write a test class in this situation, can anyone help me? I'm no apex pro.

Also- the fields being summed and sent to the account object are actually rollup fields from a child object of contact. When these fields are updated will they cause the trigger to fire? There's one of these triggers for each of our different asset amounts (8 in total).

Thanks for your help!

trigger SumBalanced on Contact (after insert,after update,after delete)
{
    Set<Id> accountIdset = new Set<Id>();
   
    for (Contact con:trigger.new)
    {
       accountIdset.add(con.AccountId);
    }
    Map<Id,Account> AccountMap = new Map<Id,Account>([Select Id,Balanced__c from Account where Id in :accountIdset]);
    for(AggregateResult res : [SELECT AccountId, SUM(Balanced__c) cnt FROM Contact where AccountId in : accountIdset GROUP BY ROLLUP(AccountId)]){
        if(res.get('AccountId') <> null){
            AccountMap.get((ID)res.get('AccountId')).Balanced__c = (Decimal)res.get('cnt');
        }
    }
    update AccountMap.values();
	}
