I am hitting the wall on this test class.  The Trigger and code are below.  Any suggestions are welcome.  It's my first try at a test class.  When running the test, my query does not seam to fire.  However, when I run it in the query editor, it pulls the correct account.  Also, none of my system.debugs show in logs when filtering for "Debug Only"

In the logs I get: "FATAL_ERROR System.QueryException: List has no rows for assignment to SObject."
 

trigger UpdateDisReg on Account (after update) {

        Account a = Trigger.New[0];
        String alias = 'a.center__c';
        System.debug(a);
        List<Lead> leadsToUpdate = [select id,CenterDistrict__c,CenterRegion__c from Lead where Owner_Alias__c = 'alias'];

        System.debug(leadsToUpdate);
        List<Lead> leads = new List<Lead>();
        
    for(Lead Leadz : leadsToUpdate) {
         leadz.CenterDistrict__c = a.District__c;
         leads.add(leadz);

Newbie here.  Trying to update multiple records when the user record of the owner is updated.  It is only updating the first record and not properly looping through/updating all as I would expect.  Any advise appreciated, been googling for hours.

trigger UpdateDistrictRegion on User (after update) {
        List<Lead> leadsToUpdate = [select id,CenterDistrict__c,CenterRegion__c from Lead where OwnerID IN :Trigger.New];
        System.debug(leadsToUpdate);
        List<Lead> leads = new List<Lead>();
        User u = Trigger.New[0];
    for(Lead Leadz : leadsToUpdate) {
         leadz.CenterDistrict__c = u.District__c;
         leads.add(leadz);
         {
       
       update leads;
}
}
}
