Help creating a test method for my Trigger

I needed a way to count the number of Contacts on an Account that have ScarbBooklet check box marked. I could not use a Roll-up summary but I did find some Apex code that I modified and it works in my Sandbox.

 

However I am not a developer and dont know how to right code at all, so I have been looking at sample test classes but I can not find one I can decypher enough to modify to as a test for my particular trigger.  

 

I was wondering if any of you devs have a few minutes to look at my trigger and point me to a bit of test code that would be very obvious that i could modify?   Thanks in advance for any help!  --Laura

 

 

/* Provide summary of Number of Scarb Booklet Contacts on Account record */

trigger ContactSumTrigger on Contact (after delete, after insert, after undelete, after update) 
{
    Contact[] cons;
    if (Trigger.isDelete)
        cons = Trigger.old;
    else
        cons = Trigger.new;

    // get list of accounts
    Set<ID> acctIds = new Set<ID>();
    for (Contact con : cons) 
    {
            acctIds.add(con.AccountId);
    }
    Map<ID, Contact> contactsForAccounts = new Map<ID, Contact>([select Id,AccountId from Contact where AccountId in :acctIds and Scarborough_Booklet__c=True]);

    Map<ID, Account> acctsToUpdate = new Map<ID, Account>([select Id,Num_of_Scarb_Booklet_Contacts__c from Account where Id in :acctIds]);

    for (Account acct : acctsToUpdate.values()) 
    {
    Set<ID> conIds = new Set<ID>();
        for (Contact con : contactsForAccounts.values()) 
        {
            if (con.AccountId == acct.Id)
                conIds.add(con.Id);
        }
        if (acct.Num_of_Scarb_Booklet_Contacts__c != conIds.size())
            acct.Num_of_Scarb_Booklet_Contacts__c = conIds.size();
    }

    update acctsToUpdate.values();

}

Hi Laura,
 
 Test Coverage:
 
 
public class TestClassContact {	public static  testMethod void testContactSum()	{		Account a = new Account(Name='Test Account');		insert a; 						Contact c1 = new Contact(LastName='Last', email='test@testemail.com',AccountId=a.Id,Scarborough_Booklet__c=true);		Contact c2 = new Contact(LastName='Last2', email='test2@testemail.com',AccountId=a.Id,Scarborough_Booklet__c=true);		Contact c3 = new Contact(LastName='Last3', email='test3@testemail.com',AccountId=a.Id,Scarborough_Booklet__c=false);				insert c1;				a = [Select Num_of_Scarb_Booklet_Contacts__c from Account where Id=:a.Id];		System.assertEquals(a.Num_of_Scarb_Booklet_Contacts__c, 1);				insert c2;				a = [Select Num_of_Scarb_Booklet_Contacts__c from Account where Id=:a.Id];		System.assertEquals(a.Num_of_Scarb_Booklet_Contacts__c, 2);				insert c3;				a = [Select Num_of_Scarb_Booklet_Contacts__c from Account where Id=:a.Id];		System.assertEquals(a.Num_of_Scarb_Booklet_Contacts__c, 2);				delete c2;				a = [Select Num_of_Scarb_Booklet_Contacts__c from Account where Id=:a.Id];		System.assertEquals(a.Num_of_Scarb_Booklet_Contacts__c, 1);					}}

Test Methods are written to ensure that the data being created in them traverses each if-else conditions and loops in a given functionality, so that your code is covered. In your simply adding the code for:-

1. Insert of contact with the value of the Scard Booklet to true and false
2. Update of Contact
3. Deletion of Contact

Please refer to the code below:-

@isTestprivate class ClassTesting
 { 
  //Added for security review 
  public static testMethod void myUnitTestQfp()
 {        // TO DO: implement unit test
Account inst = new Account(RecordTypeId = RecInst,Familiar_Name__c='@isTest1',Name='@isTest1');        insert inst;
 Contact con1 = new Contact(LastName = 'Xyz@isTest' ,AccountId = inst.Id,Scarborough_Booklet__c=True);
  insert con1;
Contact con2 = new Contact(LastName = 'Abc@isTest' ,AccountId = inst.Id,Scarborough_Booklet__c=False);
  insert con1;
con1.Scarborough_Booklet__c=False;
  update con1;
con2.Scarborough_Booklet__c=True;
  update con2;
delete con1;
delete con2;
}

}

Hope this is helpful.
