I want to restrict the following characters ‘ “ , * % @ and if possible remove any extra spaces at the end of the field. I've found validation rules for allowing characters but none for just restricting, I don't really want to have to input every single charachter other than those listed above. (infact when I try to do that I get syntax errors). Any guidence would greatly be appreciated.

Looking for help to get my test class working properly. The Code, Trigger, and Test class are listed below... Thanks in advance.

I'm looking for the best way to accomplish assigning a permmision set when a new user is created without me having to manually do it. I'd like to do this via flow/process builder but I'm not having luck with that. Anyone have any insite or suggestions on how to do this task?

This is my class, test class, and trigger. When I try to deploy to Production my trigger recieves 0% coverage. I'm a complete beginner and unable to figure this out, your help is greatly apprecitated. 

Class -
public with sharing class TaskTriggerHelper2 {

    public static void assignTaskType(List<Task> newTasks)
    {
        for(Task aTask : newTasks)
        {
            if(aTask.Subject.contains('Obtain Updated ADS Cost from Supplier'))
            {
                aTask.Type = 'Supplier Update Request';
            }
        }
    }
}

Test Class -
@isTest
public with sharing class TaskTriggerHelper2TEST{
    public static testMethod void testTaskTriggerHelper2TEST(){      
        list <task> newTasks = new list <task> ();
        task aTask = new task();
        atask.subject = 'Obtain Updated ADS Cost from Supplier';
        atask.Status = 'Not Started';    
        atask.Priority = 'Normal';
       
        insert newTasks;
    }   
}

Trigger -
trigger Task2 on Task (before insert)
{
if(Trigger.isBefore && Trigger.isInsert)
    {
        TaskTriggerHelper2.assignTaskType(Trigger.new);
    }
}

I need to have a user assigned in order to make this test class actually function. My actual class and trigger work as designed, but the test class fails because it requires a user to be present in order to work. Here is the code I have. I'm very new to apex and coding all together so I'm kinda stuck. 

@isTest
public with sharing class UpdateNCMOwnerHandlerTest
{
public static testMethod void testUpdateNCMOwnerHandler()
{
  List<Non_Conforming_Material__c> nonConformingMaterials = new List<Non_Conforming_Material__c>();
Non_Conforming_Material__c nonConformingMaterial = new Non_Conforming_Material__c(NCM_Stage__c = 'In Process'); //#1
  nonConformingMaterials.add(nonConformingMaterial);
  nonConformingMaterial = new Non_Conforming_Material__c(NCM_Stage__c = 'Resolution'); //#2
  nonConformingMaterials.add(nonConformingMaterial);
  insert nonConformingMaterials;
    }
}

My Trigger is a follows. I know this should properly be done by calling a method in a class via the trigger and in order to move this to production I need to have this in a class and then create the test class. I'm ultra new at all of this and really appreciate any help that you can provide. 

trigger UpdateNCMOwner on Non_Conforming_Material__c (before insert, before update) {
            for(Non_Conforming_Material__c n : Trigger.new){
                if(n.NCM_Stage__c == 'In Process'){
                   n.OwnerID = n.NCM_Supplier_Buyer_ID__c;
                }
                else if (n.NCM_Stage__c == 'Resolution'){
                       n.OwnerID = n.NCM_Created_By_ID__c;
                }
             }
}
