i have one custom field called Unique_Vendor_Id__c on account object (external id checkbox checked) and its auto-number.
now in test class when i create account for test data Unique_Vendor_Id__c should be automatically created as soon as account created, and in controller i am fetching data from that Unique_Vendor_Id__c if available.
now when i run test class it gives me following error :
System.StringException: Invalid id: null
and in stack trace :
External entry point Class.VendorAndChargeCreationControllerTest.VendorAndChargeCreationControllerTestMethod1: line 45, column 1
so from this error i think autonumber field is not generating id at a time of account creation am i right?
please let me know do i have to change any thing in field for generating that autonumber field in test data?
thank you in advance.
