Hi all,

i have an apex class ,

global class TwilioWeeklyScheduleSMS Implements Schedulable
{
    global void execute( SchedulableContext sc )
    {
        ScheduledSMS();
    }
    public void ScheduledSMS()
    {
        String message = 'SMS messages were sent to the following accounts:\n';
        
        List<Account> acc = [SELECT Id, Name, Mobile__c from Account where Weekly_Scheduled_SMS__c = true];
    
        if ( acc.isEmpty() ) return;
       
        Set<String> sendToPhones = new Set<String>();
    
        for ( Account a: acc )
        {
            sendToPhones.add( a.Mobile__c );
            message += a.Name + '\n';
        }    
        TwilioMessageHelper.sendSMSMessage( sendToPhones, 'Test SMS' );

        List<SMS_History__c> list_SMS_Histories = new List<SMS_History__c>();   
        for ( Account a: acc )
        {
            list_SMS_Histories.add
            (   new SMS_History__c
                (   Account__c          = a.Id,
                    Message__c          = 'Test SMS ',
                    Mobile_Number__c    = a.Mobile__c
                )
            );
        }
        insert list_SMS_Histories;
        Messaging.SingleEmailMessage emailMsg = new Messaging.SingleEmailMessage();
        emailMsg.setToAddresses( new List<String>{'rajesh.dulhani@nanostuffs.com' } );
        emailMsg.setSenderDisplayName( 'TwilioSchedule_Weekly_SMS' );
        emailMsg.setSubject( 'SMS Messages Sent' );
        emailMsg.setPlainTextBody( message );
        Messaging.sendEmail( new Messaging.SingleEmailMessage[] { emailMsg } );
    }
}

i have written the following test code ,

@istest(seeAllData=false)
public class TestTwilioWeeklyScheduledSMS {
    private static testmethod void TestTwilioWeeklyScheduledSMS (){
    
        List<Account> acc = [SELECT Id, Name, Mobile__c from Account where Weekly_Scheduled_SMS__c = true];
        if ( acc.isEmpty() ) return;
       
        TwilioWeeklyScheduleSMS sms  = new TwilioWeeklyScheduleSMS ();
        sms.ScheduledSMS();
        
    }
}

i run this test it passed but still the code coverage is 0 % . What should i modify in this test class . please help
