How to write test class for After delete & update triggers?

Hi Team,

After delete & update code not covered in trigger. please give me any idea about this requirement.

Trigger:
---------- 
trigger FinancialsCountTrigger on Financials__c (after insert, after update, after delete, after undelete) {
    
    if(checkRecursive.runOnce()){
        
        List<Account> updateAcc = new List<Account>();
        Set<Id> accid = new Set<Id>();
        
        Decimal totalRevenue;
        Decimal totalEBITDA;
        
        if(Trigger.isAfter && (Trigger.isInsert || Trigger.isUpdate || Trigger.isUndelete)){
            for(Financials__c fin : Trigger.New){
                if(fin.AccountName__c != null){
                    accid.add(fin.AccountName__c);
                }
            }
        }
        
        if(Trigger.isAfter && (Trigger.isUpdate || Trigger.isDelete)){
            for(Financials__c fin : Trigger.Old){
                if(fin.AccountName__c != null){
                    accid.add(fin.AccountName__c);
                    //system.debug('-----'+accid);
                }
            }
        }
        
            if(accid.size() > 0){
            List<Account> acclist = [select id,Name,Global_Revenue_Total__c,Global_EBITDA_B4_Total__c,
                                     (select id,Global_Revenue_Total__c,Global_EBITDA_B4_Total__c from Financial__r) from Account where id in :accid];
            
            for(Account acc : acclist){
                
                
                List<AggregateResult> aggres = [Select sum(Global_Revenue_Total__c)revtot,sum(Global_EBITDA_B4_Total__c)ebitdatot
                                                from Financials__c where AccountName__c=:acc.id and Year__c='FY-2017'];
                for(AggregateResult ag : aggres){
                    totalRevenue = (Decimal)ag.get('revtot');
                    totalEBITDA = (Decimal)ag.get('ebitdatot');
                }
                acc.Global_Revenue_Total__c = totalRevenue;
                acc.Global_EBITDA_B4_Total__c = totalEBITDA;
                updateAcc.add(acc);
            }
          }
          update updateAcc;
        
    }
    
}
Test Class
----------------- 
@isTest
public class TestFinancialsCountTrigger {
    
    public static testMethod void financialCount(){
        
        Account acc = new Account(Name='3M Corporation',Industry='Conglomerate');
        insert acc;
        
        Account acc2 = new Account(Name='3M Corporation2',Industry='Conglomerate');
        insert acc2;
        
        Financials__c fin = new Financials__c(AccountName__c=acc.id,Name='Test',Year__c='FY-2017',Global_Revenue_Total__c=100,Global_EBITDA_Total__c=200);
        insert fin;
        
        Financials__c fin2 = new Financials__c(AccountName__c=acc2.id,Name='Test2',Year__c='FY-2017',Global_Revenue_Total__c=500,Global_EBITDA_Total__c=400);
        insert fin2;
        
        fin.Global_Revenue_Total__c = 500;
        update fin;
        delete fin;
                
        Test.startTest();
        
        List<Financials__c> finlist = [select id from Financials__c where AccountName__c = :acc.Id and Year__c='FY-2017'];
        delete finlist;
        
        Test.stopTest();

Hi Lakshmi,

For after delete:
 
You can check that you receive the exception as expected.  E.g. 
try
{
   delete o1;
   // should throw exception, so fail test if get this far
   System.assert(false, 'Exception expected');
}
catch (Exception e)
{
   // expected exception
}

Thanks
Vinod

Hi Lakshmi,

In trigger change follwoing line Trigger.isAfter && (Trigger.isUpdate || Trigger.isDelete)
to Trigger.isAfter && Trigger.isDelete)
​.

And try once.
  
@isTest
public class TestFinancialsCountTrigger {
    
    public static testMethod void financialCount(){  

 Test.startTest();


        
        Account acc = new Account(Name='3M Corporation',Industry='Conglomerate');
        insert acc;
        
        Account acc2 = new Account(Name='3M Corporation2',Industry='Conglomerate');
        insert acc2;
        
        Financials__c fin = new Financials__c(AccountName__c=acc.id,Name='Test',Year__c='FY-2017',Global_Revenue_Total__c=100,Global_EBITDA_Total__c=200);
        insert fin;
        
        Financials__c fin2 = new Financials__c(AccountName__c=acc2.id,Name='Test2',Year__c='FY-2017',Global_Revenue_Total__c=500,Global_EBITDA_Total__c=400);
        insert fin2;
        
        fin.Global_Revenue_Total__c = 500;
        update fin;
        delete fin;
                
     
        

        Test.stopTest();
        
        
    }

}



Hope this helps you!

Hi Varaprasad,

Thanks for your reply.
It's not working, it covered only 88% of code coverage.
I want to 100% code coverage.
