Test class error data type. please help me!!

Hello!
I developed an apex class for read cases and send email if meet the criteria. It has 100% code coverage, but when I send the test class to production I have the following error:
"Invalid type: NotifCasosSchedule"

This is the test class:
@isTest
public class NotifCasosScheduleTest {
public static testmethod void test1(){
Test.startTest();

ID Owner = '00540000004ADl6';
Case ccs = new Case();
ccs.Area__c = 'Sistemas';
ccs.Tipo_de_Caso__c = 'Soporte Salesforce';
ccs.OwnerId = Owner;
ccs.Subject = 'test';
ccs.Description = 'Testeo';
ccs.CreatedDate__c = System.Date.today()-3;
insert ccs;

String CRON_EXP = '0 0 0 3 9 ? 2022';
String jobId = System.schedule('NotifCasosScheduleTest', CRON_EXP, new NotifCasosSchedule());
CronTrigger ct = [SELECT Id, CronExpression, TimesTriggered, NextFireTime FROM CronTrigger WHERE id = :jobId];
System.assertEquals(0, ct.TimesTriggered);
System.assertEquals('2022-09-03 00:00:00', String.valueOf(ct.NextFireTime));
Test.stopTest();

}
}
