Hi...Actually I have written 2 triggers and I need test class for these two triggers...
1. Trigger to update contact description whenever account description is updated with the same value of account description...

trigger acc on account(after update)
{
set<id> accids = new set<id>();
for(account a : trigger.new)
{
accids.add(a.id);
}
list<contact> conlist=[select id,account.description, description from contact where accountid=: accids];
for (contact c: conlist)
{
c.description=c.account.description;
}
update conlist;
}

2.) Whenever account is created then create contact with the account details ...

trigger createcon on account(after insert)
{
list<contact> conlist = new list<contact>();
for (account a:trigger.new)
{
contact c = new contact();
c.lastname= a.name;
c.accountid=a.id;
conlist.add(c);
}
insert conlist;
}


Kindly need test classes for the above 2 triggers. 
Any help on writing the test classes would be of great help....Thanks...
Thanks in advance...

Hi ,

This is my test class for insert a record

Parent Object :Album__c
Child object :Track__c(which has loopup relation with Album__C)

I have written the class and the test class for inserting a record in the child object...but both are giving me error....

In main program
----------------------

public class instrack 
{
track__c al = new track__c(); 
public track__c merch(String name,string name1)  
{
al.Name=name;                             
al.Album__c=name1;
insert al;                 
system.debug('the inserted record is:'+name);
return al;
}
}

Executed as :

instrack mc=new instrack();
mc.merch('Container','GullyBoy');

Error as: Method does not exist  or incorrect signature :void merch(string) from the type instrack....

Test class
-------------
@istest
public class instracktest
{
static testmethod void testmerch()
{
track__c al = new track__c(Name='Surgical'); 
 insert al;   
 Test.startTest();
         al = new track__c (Name = 'Surgical',Album__c='GullyBoy');
         Database.SaveResult result = Database.insert(al, false);
         System.assert(result.getErrors()[0].getMessage().contains('Track already exist with this'));
        Test.stopTest();              

}
}

Error as : System.DmlException: Insert failed. First exception on row 0; first error: REQUIRED_FIELD_MISSING, Required fields are missing: [Album__c]: [Album__c]

Kindly help out on the issue..Thanks in advance...
