I get 80% test coverage but want 100.  Any ideas how I can get this class to pass 100%.  Class below, followed by the 2 test methods.  The failure is on the execute method in the class.  Tests won't cover it and I can't figure out why

CLASS

global class deleteAccounts implements  Database.Batchable<sObject>, Schedulable {
String query = 'SELECT id from Account WHERE Name=test';
global deleteAccounts ()
{
}
  global void execute(SchedulableContext SC) {
      deleteAccounts x = new deleteAccounts(); 
      database.executebatch(x);
   }
global Database.QueryLocator start(Database.BatchableContext BC){
   return Database.getQueryLocator([SELECT id FROM Account WHERE Name ='test']);
}
global void execute(Database.BatchableContext BC, List<sObject> scope){
  delete scope;
}
global void finish(Database.BatchableContext BC){

 }}

 TEST METHODS:

public class TEST_deleteAccounts{
public static testMethod void testBatch() {

   List <Account> accns = new List<Account>();
      for(integer i = 0; i<200; i++){
         Account a = new Account(Name='test'+'i'); 
         accns.add(a);
      }
   
   insert accns;
   
   Test.StartTest();
   deleteAccounts  x = new deleteAccounts();
   ID batchprocessid = Database.executeBatch(x);
   Test.StopTest();

   System.AssertEquals(
           database.countquery('SELECT COUNT()'
              +' FROM Account WHERE Name=test'),
           0);  
   
   }
}

public class TEST_deleteAccountsschedjob{
public static testMethod void testBatch() {
   deleteAccounts a = new deleteAccounts();
   String sch = '0 0 23 * * ?';
  
   Test.startTest();
   Id jobId = System.schedule('a', sch, a);
  
   // Get the CronTrigger info prior to the run
CronTrigger cronTrigger1 = [SELECT Id, CronExpression, TimesTriggered, NextFireTime FROM CronTrigger WHERE Id = :jobId];

// Assert that the expressions are the same
System.assertEquals(sch, cronTrigger1.CronExpression);

// Assert that the cron job has not started
System.assertEquals(0, cronTrigger1.TimesTriggered);

   Test.stopTest(); // will execute the asynchronous Apex
  
   // Get the CronTrigger info prior to the run
CronTrigger cronTrigger_after = [SELECT Id, CronExpression, TimesTriggered, NextFireTime FROM CronTrigger WHERE Id = :jobId];

   // Assert that the cron job has run once
System.assertEquals(1, cronTrigger_after.TimesTriggered);
  }
