TheFrisco Test Class Problems with System.NullPointerException: Attempt to de-reference a null
OK, gonna keep this short ... I am new to Apex and especially writing test classes is giving me a headache ... HELP PLEASE!!!
Here is the class ... (took out some code and replaced with ... for easier reading)
public class DoPaymentHandler{
public DoPaymentHandler(){
}
public DoPaymentHandler(ApexPages.StandardController controller) {
this.reg = (Registration__c)controller.getRecord();
}
...
//Handling payment processing submitting by VF page button
public void process(){
isSuccess = false;
amount = String.valueOf(reg.Open_Amount__c);
ponumber = reg.Event__r.PO_Number__c;
description = reg.Event__r.Name;
firstname = reg.Participant__r.First_Name__c;
lastname = reg.Participant__r.Last_Name__c;
email = reg.Participant__r.Email__c;
state = reg.Participant__r.Billing_State__c;
zip = reg.Participant__r.Billing_ZIP__c;
cardnumber = reg.Participant__r.Credit_Card__c;
expiration = reg.Participant__r.Expiration_Date__c;
if(!validate()){
isSuccess = false;
return;
}
AuthorizeDotNet ath = new AuthorizeDotNet(isTest);
ath.transaction(cardnumber, expiration, amount, '','','');
ath.setParameter('x_device_type','1');
ath.setParameter('x_first_name',firstname);
ath.setParameter('x_last_name',lastname);
// ath.setParameter('x_address',address);
ath.setParameter('x_state',state);
ath.setParameter('x_response_format','1');
ath.setParameter('x_zip',zip);
ath.setParameter('x_po_num',ponumber);
ath.setParameter('x_description',description);
try{
ath.process(3);
}catch(Exception ex){
ApexPages.addmessage(new ApexPages.message(ApexPages.severity.Error, ex.getMessage()));
isSuccess = false;
}
...
}
private boolean validate(){
...
}
}
Here is the test class ...
public class TestAuthorizeDotNetLib{
@isTest
private static void testclasses(){
DoPaymentHandler doPayment = new DoPaymentHandler();
doPayment.process();
doPayment.amount='test';
doPayment.ponumber='test';
doPayment.description='test';
doPayment.firstname='test';
doPayment.lastname='test';
doPayment.email='test';
doPayment.state='test';
doPayment.zip='test';
doPayment.cardnumber='test';
doPayment.expiration='test';
doPayment.process();
}
}
When running the test I get the error message "Problems with System.NullPointerException: Attempt to de-reference a null" on the line with "doPayment.process();"
Help is much appreciated.

It's failing probably because the reg inside the class is null, since you
didn't provide this data.
I think you can do it in 2 ways:
1.Provide the class this data
doPayment.reg = new Registration__c();
2.Test it by mimic the action of opening the page
Registration__c myReg=new Registration__c();
Test.setCurrentPageReference(new PageReference('Page.thePageName'));
ApexPages.StandardController sc = new ApexPages.standardController(myReg);
DoPaymentHandler contClass = new DoPaymentHandler(sc);
contClass.process();
Note that in either case, you should create the data - Registration__c.
When the text class running, it's start with empty tables, you need to create it before.

Thanks I used the second approach and that got me to where I could package my code. YOU ROCK!!!
