Batch apex test code covrage only 10% in production

Hi Experts,
I have a batch class to send email reminders to task owners if their task due date are overdue with all task links. I have wrote test class and run test class for code covrage.
Code covrage 80% in sandbox but when I deployed it in production and check code covtage it is showing only 10%. Please help in this issue.
Below is my code.
 
global class SendEmailToDueDateTask implements Database.Batchable<sObject>  {
    map<string,list<task>> userEmailTasklistmap = new map<string,list<task>>();
    
    global Database.QueryLocator start(Database.BatchableContext BC){
        return Database.getQueryLocator([SELECT ID,createddate,what.id,Owner.Email,OwnerId,owner.name,Status,ActivityDate,Subject from Task WHERE Status != 'Completed' and owner.isactive = true and ActivityDate =: system.today() ]);
    }
    
    global void execute(Database.BatchableContext BC, List<Task> scope){
        for(Task Tsk : scope){
            if(!userEmailTasklistmap.Containskey(tsk.owner.email)){
                userEmailTasklistmap.put(tsk.owner.email, new list<task>());
            }
            userEmailTasklistmap.get(tsk.owner.email).add(tsk);
            
          }  
        List<Messaging.SingleEmailMessage> mails = new List<Messaging.SingleEmailMessage>();
    
            for(string email : userEmailTasklistmap.keyset()){
                
                Messaging.SingleEmailMessage mail = new Messaging.SingleEmailMessage();
                list<string> toAddresses = new list<string>();
                toAddresses.add(email);
                mail.setToAddresses(toAddresses);
                mail.setSubject('Details of tasks due for today');                
                String username = userEmailTasklistmap.get(email)[0].owner.name;
                String htmlBody = '';
                
                htmlBody = '<table width="100%" border="0" cellspacing="0" cellpadding="8" align="center" bgcolor="#F7F7F7">'+
                            +'<tr>'+
                              +'<td style="font-size: 14px; font-weight: normal; font-family:Calibri;line-height: 18px; color: #333;"><br />'+
                                   +'<br />'+
                                    +'Dear '+username+',</td>'+
                            +'</tr>'+
                            +'<tr>'+
                                +'<td style="font-size: 14px; font-weight: normal; font-family:Calibri; line-height: 18px; color: #333;">You have Pending Task</td>'+
                            +'</tr>'+
                        +'</table>';
 
                htmlBody +=  '<table border="1" style="border-collapse: collapse"><tr><th>Related To</th><th>Subject</th><th>Created Date</th><th> Due Date</th></tr>';
                for(task tsk : userEmailTasklistmap.get(email)){
                    
                    String duedate = '';
                    if (tsk.ActivityDate != null)
                        duedate = tsk.ActivityDate.format();                    
                    else
                        duedate = '';
                    String Subject = tsk.subject;
                    datetime dt = tsk.createddate;
                    string createddate = dt.format('M/d/yyyy');
                    string what = tsk.what.id;
                    string link = URL.getSalesforceBaseUrl().toExternalForm()+'/'+ tsk.id; 
                    htmlBody += '<tr><td>' + what + '</td><td>' + Subject + '</td><td>' + createddate + '</td><td>' + duedate + '</td></tr>';                    
                }
                 htmlBody += '</table><br>';
                 mail.sethtmlBody(htmlBody);
                 mails.add(mail);                    
            }
             if(mails.size()>0)
             Messaging.sendEmail(mails);
    }
    global void finish(Database.BatchableContext BC){        
    }
}

And Test class is:
 
@isTest 
public class SendEmailToDueDateTaskTest {
    static testMethod void testMethod1(){
		Profile pro = [SELECT Id FROM Profile WHERE Name='Standard User']; 
		User usr = new User(Alias = 'standt', Email='standarduser@tt.com', 
		EmailEncodingKey='UTF-8', LastName='Testing', LanguageLocaleKey='en_US', 
		LocaleSidKey='en_US', ProfileId = pro.Id, 
		TimeZoneSidKey='America/Los_Angeles', UserName='standarduser@tt.com');
		System.runAs(usr) {
			Account acc = new Account();
				acc.Name = 'Test Account';
				insert acc;
				acc=[SELECT id,Name FROM account WHERE id=:acc.Id];
				System.assertEquals(acc.Name,'Test Account');
            Task tsk = new Task();
				tsk.whatId = acc.Id; 
				tsk.Subject = 'Testing';
				tsk.Status = 'In Progress';
				tsk.Priority = 'Normal';
				tsk.ActivityDate = System.today();
				insert tsk ;
				tsk=[SELECT id,Status FROM Task WHERE id=:tsk.Id];
				System.assertEquals(tsk.Status ,'In Progress');
            }
			Test.StartTest();
				Database.executeBatch (new SendEmailToDueDateTask (),200);
			Test.StopTest();
    }
 }

Please let me know why code covrage on 10%.

You created the user obect but forget to insert the user record.

Please try below test class
@isTest 
public class SendEmailToDueDateTaskTest 
{
    static testMethod void testMethod1()
	{
		Profile pro = [SELECT Id FROM Profile WHERE Name='Standard User'];
		
		User usr = new User(Alias = 'standt', Email='standarduser@tt.com', 
		EmailEncodingKey='UTF-8', LastName='Testing', LanguageLocaleKey='en_US', 
		LocaleSidKey='en_US', ProfileId = pro.Id, 
		TimeZoneSidKey='America/Los_Angeles', UserName='standarduser@tt.com');
		
		insert usr;
		
		System.runAs(usr) {
			Account acc = new Account();
				acc.Name = 'Test Account';
				insert acc;
				acc=[SELECT id,Name FROM account WHERE id=:acc.Id];
				System.assertEquals(acc.Name,'Test Account');
            Task tsk = new Task();
				tsk.whatId = acc.Id; 
				tsk.Subject = 'Testing';
				tsk.Status = 'In Progress';
				tsk.Priority = 'Normal';
				tsk.ActivityDate = System.today();
				insert tsk ;
				
				tsk=[SELECT id,Status FROM Task WHERE id=:tsk.Id];
				System.assertEquals(tsk.Status ,'In Progress');
            }
			Test.StartTest();
				Database.executeBatch (new SendEmailToDueDateTask (),200);
			Test.StopTest();
    }
 }

You Can also try below test class without creating the user
@isTest 
public class SendEmailToDueDateTaskTest 
{
    static testMethod void testMethod1()
	{
			Account acc = new Account();
				acc.Name = 'Test Account';
				insert acc;
			acc=[SELECT id,Name FROM account WHERE id=:acc.Id];
			System.assertEquals(acc.Name,'Test Account');
			
            Task tsk = new Task();
				tsk.whatId = acc.Id; 
				tsk.Subject = 'Testing';
				tsk.Status = 'In Progress';
				tsk.Priority = 'Normal';
				tsk.ActivityDate = System.today();
				insert tsk ;
			tsk=[SELECT id,Status FROM Task WHERE id=:tsk.Id];
			System.assertEquals(tsk.Status ,'In Progress');
            
			Test.StartTest();
				Database.executeBatch (new SendEmailToDueDateTask (),200);
			Test.StopTest();
    }
 }
