Hi ,

     I have a trigger which generates the standard field, Name of a custom object with  'a string + name of the corresponding Contact' before inserion/Updation.

My trigger:--

____________________________________________________________________________________________

trigger trgname on cusobj__c (before insert,before update) {
Set<ID> conid = new Set<ID>();
List<contact> lstContact = new List<contact>();
Map<ID,contact> Mapname = new Map<ID,contact>();
for( cusobj__c tar :Trigger.New)
{
conid.add(tar.Contact__c); // Storing all the contact ids for which the name needs to be used
}
system.debug('Inside the trigger to update the name');
//Getting all the contact records in a list to be used in the name field
lstContact = [select id,name,firstname,lastname from contact where id in : conid];

for(integer i =0; i <lstcontact.size(); i++)
{
Mapname.put(lstcontact[i].id,lstcontact[i]); // Putting the contact id and name in a map
}

for( cusobj__c tar :Trigger.New)
{
// tar.name = 'TD Rem - ' + mapname.get(tar.Contact__c).firstname +' ' + mapname.get(tar.Contact__c).lastname;
tar.name = 'TD Rem - ' + mapname.get(tar.Contact__c).name;
}

}

I do have a test class for this trigger . But getting  error 'Assertion Failed: Expected: 20, Actual: 0' 

My Testclass:-

____________________________________________________________________________________________

@isTest
Private class testTrgTrgname{
Static testMethod void methodname(){
Contact con = new Contact();
con.FirstName= 'fname';
con.LastName = 'lname';

insert con;
System.debug('value for contact name:' + con);
Contact con1 = new Contact();
con1.LastName = 'lname1';
insert con1;
//Insert test data

cusobj__c Tmapt = new cusobj__c();
Tmapt.Appointment_Created__c = True;
Tmapt.Target_date__c = System.today()+3;
Tmapt.Contact__c = con.id;

insert Tmapt;
System.debug('value for Tmapt name:' + Tmapt.Name);
System.debug('value for Tmapt :' + Tmapt);
List<cusobj__c> ltmd = new List<cusobj__c>();
ltmd =[Select Contact__c from cusobj__c where id =:Tmapt.id];
System.assertEquals(1,ltmd.Size());

System.assertEquals('TD Rem-fname lname', Tmapt.Name);
cusobj__c Tpt = new cusobj__c();
Tpt.Appointment_Created__c = True;
Tpt.Target_date__c = System.today()+ 5;
Tpt.Contact__c =con1.id;
insert Tpt;
System.assertEquals(Tpt.Name, con1.name);
Contact newcon = new Contact();
newcon.lastname = 'lnewcon';
insert newcon;
//cusobj__c Ltar =[Select Contact__c from cusobj__c where id := Tmapt.id];
//Tmapt.Cotnact__c = newcon.id;
//update Tmapt;

}
}
