private class TestOnecontactforoneaccount {
    static testMethod void testOneCon(){
        
        Account a = new Account(name='test acc',phone='9494146144');
        insert a;

Hi Lakshmi,

The code  
Trigger.oldmap.get(con.id).addError('Duplicate account id');
does'nt covers the test data. Because Trigger.oldmap context variable is available in update and delete triggers. So i have just updated a new value with the previous value.

The below is my code, negativeTest() is what i have cerated. 
@isTest
private class TestOnecontactforoneaccount {
    static testMethod void testOneCon(){
        
        Account a = new Account(name='test acc',phone='9494146144');
        insert a;
        Account a2 = new Account(name='test acc 2',phone='9494146144');
        insert a2;
        Contact con = new Contact(accountid=a.id,lastname='test con',email='lnarasimha823@gmail.com');
        insert con;
        Contact con2 = new Contact(accountid=a.id,lastname='test con2',email='lnarasimha823@gmail.com');
        
        Test.startTest();
        try{
            insert con2;
        }
        catch(Exception e){
           system.debug('Duplicate Account Id');
        }
        Test.stopTest();
        }    
        static testMethod void negativeTest(){    
        Test.startTest();
        Account a = new Account(name='test acc1',phone='9494146144');
        insert a;
        Account a1 = new Account(name='test acc1',phone='9494146144');
        insert a1;   
        Contact con = new Contact(accountid=a.id,lastname='test con1',email='lnarasimha823@gmail.com');
        insert con;
        Contact con3 = new Contact(accountid=a1.id,lastname='test con',email='lnarasimha823@gmail.com');
         insert con3;
            con3.lastname = 'lastname';
            con3.accountid = a.id;
        try{
             update con3;
        }
        catch(Exception e){
           system.debug('Duplicate Account Id');
        }
        Test.stopTest();
        
    }
}
Please let us know if it does'nt works.

Lakshmi, 

Try below code. 
@isTest
private class TestOnecontactforoneaccount {
    static testMethod void testOneCon(){
        
        Account a = new Account(name='test acc',phone='9494146144');
        insert a;
        Account a2 = new Account(name='test acc 2',phone='9494146144');
        insert a2;
        Contact con = new Contact(accountid=a2.id,lastname='test con',email='lnarasimha823@gmail.com');
        insert con;
        Contact con2 = new Contact(accountid=a.id,lastname='test con2',email='lnarasimha823@gmail.com');
        
        Test.startTest();
        try{
            insert con2;
            con.AccountId = a.id;
            update con;
        }
        catch(Exception e){
           system.debug('Duplicate Account Id');
        }
        
        
        Test.stopTest();
        
    }
}
It will cover 100 % :)

Let me know if this helps.
