how call execute method in the test class?

Here is my code.

//Controller
public with sharing class deleteEvents implements Schedulable
{
    
      public void execute(SchedulableContext SC) 
       {
           
            
            List<Login__c> query=[SELECT Id, Name FROM Login__c WHERE CreatedDate != LAST_N_DAYS:10 and CreatedDate < today ];
            
        List<Login__c> con= query;
        
        if(con!=null)
        {
            delete con;
            }
        }
}

//testclass
@isTest
private class deleteeventsTest{
static List<Login__c> logins = new List<Login__c>();

static testmethod void Test(){
Test.StartTest();


//insert test data
Login__c log=new Login__c();
//fill all mandatory fields needed
log.Name ='testing';
log.Email__c='test@gmail.com';
insert log;

deleteEvents deleve=new deleteEvents();
deleve.execute();
String schedule = '0 15 12 15 1-12 ? *';
List<Login__c> objectList = new List<Login__c>(); 
Test.stopTest();
}
}

I am getting Error: Compile Error: Method does not exist or incorrect signature: [deleteEvents].execute() at line 17 column 1
Please help as how to solve it?

Please check below post for Batch job and scheduler. I hope that will help you
1) http://amitsalesforce.blogspot.in/search/label/Batch%20Job

Please try below test class
@isTest
private class deleteeventsTest
{
	static List<Login__c> logins = new List<Login__c>();
    public static String CRON_EXP = '0 0 0 15 3 ? 2022';

	static testmethod void Test()
	{
		Login__c log=new Login__c();
		//fill all mandatory fields needed
		log.Name ='testing';
		log.Email__c='test@gmail.com';
		insert log;

		Test.StartTest();


			String jobId = System.schedule('ScheduleApexClassTest',  CRON_EXP,  new deleteEvents ());
			CronTrigger ct = [SELECT Id, CronExpression, TimesTriggered,   NextFireTime FROM CronTrigger WHERE id = :jobId];
			System.assertEquals(CRON_EXP,  ct.CronExpression);

		Test.stopTest();
	}
}
Let us know if this will help you

Hi Shruthi,

Please find the below Test Class:
 
@isTest
public class DeleteEvents Test {
	static testMethod void testMethodOne() {		
		
        String CRON_EXP = '0 0 1 * * ?';
        
        Test.startTest();
		
		//insert test data
		Login__c log=new Login__c();
		//fill all mandatory fields needed
		log.Name ='testing';
		log.Email__c='test@gmail.com';
		insert log;

        // Schedule the test job
        String jobId = System.schedule('ScheduleApexClassTest', CRON_EXP, new deleteEvents());
             
        // Get the information from the CronTrigger API object
        CronTrigger ct = [SELECT Id, CronExpression, TimesTriggered, NextFireTime FROM CronTrigger WHERE id = :jobId];
        
        Test.stopTest();
    }
}

Please check below post for test classes.
1) https://developer.salesforce.com/page/An_Introduction_to_Apex_Code_Test_Methods

Please follow below salesforce Best Practice for Test Classes :

1. Test class must start with @isTest annotation if class class version is more than 25
2. Test environment support @testVisible , @testSetUp as well
3. Unit test is to test particular piece of code working properly or not .
4. Unit test method takes no argument ,commit no data to database ,send no email ,flagged with testMethod keyword .
5. To deploy to production at-least 75% code coverage is required
6. System.debug statement are not counted as a part of apex code limit.
7. Test method and test classes are not counted as a part of code limit
9. We should not focus on the  percentage of code coverage ,we should make sure that every use case should covered including positive, negative,bulk and single record .
Single Action -To verify that the the single record produces the correct an expected result .
Bulk action -Any apex record trigger ,class or extension must be invoked for 1-200 records .
Positive behavior : Test every expected behavior occurs through every expected permutation , i,e user filled out every correctly data and not go past the limit .
Negative Testcase :-Not to add future date , Not to specify negative amount.
Restricted User :-Test whether a user with restricted access used in your code .
10. Test class should be annotated with @isTest .
11 . @isTest annotation with test method  is equivalent to testMethod keyword .
12. Test method should static and no void return type .
13. Test class and method default access is private ,no matter to add access specifier .
14. classes with @isTest annotation can't be a interface or enum .
15. Test method code can't be invoked by non test request .
16. Stating with salesforce API 28.0 test method can not reside inside non test classes .
17. @Testvisible annotation to make visible private methods inside test classes.
18. Test method can not be used to test web-service call out . Please use call out mock .
19. You can't  send email from test method.
20.User, profile, organization, AsyncApexjob, Corntrigger, RecordType, ApexClass, ApexComponent ,ApexPage we can access without (seeAllData=true) .
21. SeeAllData=true will not work for API 23 version eailer .
22. Accessing static resource test records in test class e,g List<Account> accList=Test.loadData(Account,SobjectType,'ResourceName').
23. Create TestFactory class with @isTest annotation to exclude from organization code size limit .
24. @testSetup to create test records once in a method  and use in every test method in the test class .
25. We can run unit test by using Salesforce Standard UI,Force.com IDE ,Console ,API.
26. Maximum number of test classes run per 24 hour of period is  not grater of 500 or 10 multiplication of test classes of your organization.
27. As apex runs in system mode so the permission and record sharing are not taken into account . So we need to use system.runAs to enforce record sharing .
28. System.runAs will not enforce user permission or field level permission .
29. Every test to runAs count against the total number of DML issued in the process.

Please do let me know if it helps you.

Use System.schedule() method to test your execute(), add the below lines to your test class,
 
      public static String CRON_EXP = '0 0 0 15 3 ? 2022';
      String jobId = System.schedule('ScheduleApexClassTest',CRON_EXP, new MySchedulableClass());
      // Get the information from the CronTrigger API object
      CronTrigger ct = [SELECT Id, CronExpression, TimesTriggered,NextFireTime FROM CronTrigger WHERE id = :jobId];
      // Verify the expressions are the same
      System.assertEquals(CRON_EXP,ct.CronExpression);

you can find more details in https://developer.salesforce.com/docs/atlas.en-us.apex_workbook.meta/apex_workbook/apex_scheduling_2.htm

We shouldn't hard code the Cron Exp. Hence we have to use as below:

String CRON_EXP = '0 0 1 * * ?';

Also you can add Assertions:

System.assertEquals(CRON_EXP,  ct.CronExpression);
System.assertEquals(0, ct.TimesTriggered);

Thank you....:)..I got 100% code coverage with the second code...thank you....:)
Mahesh DMahesh D
Hi Shruthi,

With the above code, you will get a deployment error after 2022 April 15th. Hence we shouldn't hard code the Cron Exp.

Mahesh

Hi Mahesh / Shruthi,

You will never get a deployment before 2022 and same is document in salesforce document

Yes i agree with we should not hard code that. Please try below code.
@isTest
private class deleteeventsTest
{
	static List<Login__c> logins = new List<Login__c>();
    public static String CRON_EXP = '0 0 1 * * ?';

	static testmethod void Test()
	{
		Login__c log=new Login__c();
		//fill all mandatory fields needed
		log.Name ='testing';
		log.Email__c='test@gmail.com';
		insert log;

		Test.StartTest();


			String jobId = System.schedule('ScheduleApexClassTest',  CRON_EXP,  new deleteEvents ());
			CronTrigger ct = [SELECT Id, CronExpression, TimesTriggered,   NextFireTime FROM CronTrigger WHERE id = :jobId];
			System.assertEquals(CRON_EXP,  ct.CronExpression);
			
		Test.stopTest();
	}
}
Thanks

Yes thats the reason I posted the below answer which is 100%  appropriate:
 
@isTest
public class DeleteEventsTest {
	static testMethod void testMethodOne() {		
		
        String CRON_EXP = '0 0 1 * * ?';
        
        Test.startTest();
		
		//insert test data
		Login__c log=new Login__c();
		//fill all mandatory fields needed
		log.Name ='testing';
		log.Email__c='test@gmail.com';
		insert log;

        // Schedule the test job
        String jobId = System.schedule('ScheduleApexClassTest', CRON_EXP, new deleteEvents());
             
        // Get the information from the CronTrigger API object
        CronTrigger ct = [SELECT Id, CronExpression, TimesTriggered, NextFireTime FROM CronTrigger WHERE id = :jobId];
        System.assertEquals(CRON_EXP,  ct.CronExpression);
System.assertEquals(0, ct.TimesTriggered);
        Test.stopTest();
    }
}

This ran with 100% code coverage. Hope it helps.

@isTest
public class DailyLeadProcessorTest {
    static testmethod void testScheduledJob()
    {
        list<lead> leadup= new list<lead>();
        for(integer i=0;i<200;i++)
        {
            leadup.add(new lead(LastName='Test_Lead_'+i,LeadSource='',Company='Google'));
        }
        insert leadup;
        Test.startTest();
        
        system.schedule('testschedule', '0 24 * * * ?', new DailyLeadProcessor());
        Test.stopTest();
        
        list<lead> li=[SELECT Id,LeadSource from LEAD where LastName like 'Test_Lead_%' LIMIT 200]; 
        system.assertEquals(200, li.size());
    }
}
