Hi StephenYou still get the error as you have not re-queried the record that you have created. If you go to this thread https://developer.salesforce.com/forums/ForumsMain?id=9062I000000IKZFQA4and search for "why we grab the written record in our Apex Test Classes" you will see a post that will explain what is required and why. But if you want the short version, update your method to:
RegardsAndrew@isTest
public static void TestContactWithValidZip() {
// Test data setup
// Create a contact with a valid VA Mailing Postal Code
// and check to ensure County is updated correctly
Zip_Code__c zipCode = new Zip_Code__c(Postal_Code__c = '20101', County__c = 'Loudoun');
insert zipCode;
Contact contactValidZip = new Contact(LastName = 'Test', MailingPostalCode = '20101');
insert contactValidZip;
Contact insertedContact = [SELECT Id, Mailing_County__c FROM Contact WHERE Id = :contactValidZip.Id LIMIT 1];
// Perform Test
//general format for asserts is expected v actual so
System.assertEquals('Loudoun', insertedContact.Mailing_County__c, );
}
