Hello,

I'm really new to Apex and to code in general, so please try to not laugh at my pathetic test code. The code itself works (I tested manually) and it's a really basic trigger; the test code fails, though, and I can't figure out why. Can anyone help me figure out what's going on? Thank you!!

Trigger:

trigger SpouseTrigger on Contact (before insert) {
    List<Contact> cons = new List<Contact>();
    List<Contact> consToInsert = new List<Contact>();
    
    for(Contact c:trigger.new){
        if(c.Sig_Other_First_Name__c != null && c.Sig_Other_Last_Name__c != null){
            cons.add(c);
        }
    }
    
    for(Contact c: cons){
        Contact newCon = new Contact();
        newCon.FirstName = c.Sig_Other_First_Name__c;
        newCon.LastName = c.Sig_Other_Last_Name__c;
        newCon.AccountId = c.AccountId;
        consToInsert.add(newCon);
    }
    
    insert consToInsert;
}

Here's the test code, where something isn't working:

@istest
private class SpouseTriggerTest {

    static TestMethod void Test1_TestInsertContact() {
        Account acc = new Account(Name = 'My Account', RecordTypeid = '012A0000000dlDz');
        insert acc;
    
        Contact testC1 = new Contact(LastName='Test1 Contact', Sig_Other_First_Name__c='John', Sig_Other_Last_Name__c='Smith', AccountId = acc.Id);
        insert testC1;
        
        //pull the account info for that contact
        Contact SecContact1 = [SELECT FirstName, LastName, AccountId FROM Contact WHERE Id = :testC1.id];
        
        //verify that the insert updated by creating another contact as in the trigger
        System.assert(SecContact1.Id != null);
        System.assertEquals(SecContact1.FirstName, testC1.Sig_Other_First_Name__c);
        System.assertEquals(SecContact1.LastName, testC1.Sig_Other_Last_Name__c);
        System.assertEquals(SecContact1.AccountId, testC1.AccountId);
        
        Contact testC2 = new Contact(LastName='Test1 Contact', Sig_Other_First_Name__c=null, Sig_Other_Last_Name__c='Smith', AccountId = acc.Id);
        insert testC2;
        
        //pull the account info for that contact
        Contact SecContact2 = [SELECT FirstName, LastName, AccountId FROM Contact WHERE Id = :testC2.id];
        
        //verify that the insert updated by creating another contact as in the trigger
        System.assert(SecContact2.Id != null);
        System.assertNotEquals(SecContact2.FirstName, testC2.Sig_Other_First_Name__c);
        System.assertNotEquals(SecContact2.LastName, testC2.Sig_Other_Last_Name__c);
        System.assertNotEquals(SecContact2.AccountId, testC2.AccountId);
        
        Contact testC3 = new Contact(LastName='Test1 Contact', Sig_Other_First_Name__c='John', Sig_Other_Last_Name__c=null, AccountId = acc.Id);
        insert testC3;
        
        //pull the account info for that contact
        Contact SecContact3 = [SELECT FirstName, LastName, AccountId FROM Contact WHERE Id = :testC3.id];
        
        //verify that the insert updated by creating another contact as in the trigger
        System.assert(SecContact3.Id != null);
        System.assertNotEquals(SecContact3.FirstName, testC3.Sig_Other_First_Name__c);
        System.assertNotEquals(SecContact3.LastName, testC3.Sig_Other_Last_Name__c);
        System.assertNotEquals(SecContact3.AccountId, testC3.AccountId);
        
        Contact testC4 = new Contact(LastName='Test1 Contact', Sig_Other_First_Name__c=null, Sig_Other_Last_Name__c=null, AccountId = acc.Id);
        insert testC4;
        
        //pull the account info for that contact
        Contact SecContact4 = [SELECT FirstName, LastName, AccountId FROM Contact WHERE Id = :testC4.id];
        
        //verify that the insert updated by creating another contact as in the trigger
        System.assert(SecContact4.Id != null);
        System.assertNotEquals(SecContact4.FirstName, testC4.Sig_Other_First_Name__c);
        System.assertNotEquals(SecContact4.LastName, testC4.Sig_Other_Last_Name__c);
        System.assertNotEquals(SecContact4.AccountId, testC4.AccountId);
        
    }
}

Here's the error message I receive:
