Hi All ,

   i am writing test class for following schedule class 
      global class scheduleAccountWriteXML implements Schedulable{
    
    // Execute method
    
    global void execute(SchedulableContext SC) {
        
        try{
      
// Code to be executed when the schedule class wakes up

            
            CalloutAccountRequest.basicAuthCalloutRequest();
           
            String CRON_EXP = '0 0 * * * ?';
            string jobName = 'Account_Interface_Schedule_job_that_runs_every_1_hour_for_Accounts'; 
            scheduleAccountWriteXML p = new scheduleAccountWriteXML();
            system.schedule(jobName, CRON_EXP, p);              
            
        }     
        
        Catch (Exception e){            
            
            Messaging.SingleEmailMessage emailMessage = new Messaging.SingleEmailMessage();
           
            emailMessage.setToAddresses(new String[] { 'varaprasad.vemula@accenture.com'});
            emailMessage.setSubject('Subject');
            
          
            emailMessage.setPlainTextBody(e.getmessage());
         
            Messaging.SendEmailResult[] emailResult = Messaging.sendEmail(new Messaging.SingleEmailMessage[] { emailMessage}, true);
        }
    }
}

I received code 90%,but test execution will be fail .

@isTest
public class Test_scheduleAccountWriteXML {
    public static testmethod void testaccountxml(){
    Test.StartTest();
              
            String CRON_EXP = '0 0 * * * ?';           
            scheduleAccountWriteXML scc6= new scheduleAccountWriteXML();       
            String jobid = system.schedule('varam', CRON_EXP, scc6);  
        
     Test.StopTest();
