Hi,

I have a schedulable apex class that executes method AddRecords.
Method create a new record for object User_Tasks__c for each user account in org. One of the field User_Tasks__c.Total_tasks__c is filled with total tasks count of the user.

I am struggling to write a test class for it.
Sharing code for apex class and test class.
 

global class CreateUserTasks Implements Schedulable{
    global void execute(SchedulableContext sc){
            AddRecords();
    }
    
    public static void AddRecords(){
        List<User> users = [select id,Name from User where IsActive=true];
        Map<Id, Integer> taskCounts = new Map<Id, Integer>();
        List<AggregateResult> ars;
        List<User_Task__c> userTasks= New List<User_Task__c>();
    
        ars = [SELECT  OwnerID owner, count(ID) taskCount FROM Task WHERE OwnerId in (select id from User where IsActive=true) and isClosed = false group by OwnerId];
        
        for(AggregateResult ar : ars) {
            taskCounts.put((ID)ar.get('owner'), Integer.valueOf(ar.get('taskCount')));
            User_Task__c usertask = New User_Task__c();
            usertask.tasks_completed__c = 0;
            usertask.Date__c = System.today();
            usertask.Total_tasks__c = Integer.valueOf(ar.get('taskCount'));
            
        }
        insert userTasks;
        }
}

My test class has 0% test coverage. My test class:

@isTest
private class TestCreateUserTasks{
	static testMethod void validateSampleApex() {
        
		Test.startTest();
        
        User u1 = new user();
        u1.LastName = 'A';
        u1.Email = 'test@test.com';
        u1.Alias = 'A';
        u1.Username = 'A1234444@test.com';
        u1.CommunityNickname = 'A12';
        u1.LocaleSidKey = 'en_US';
        u1.TimeZoneSidKey = 'GMT';
        u1.ProfileID = '00e1C000001J8DbQAK';
        u1.LanguageLocaleKey = 'en_US';
        u1.EmailEncodingKey = 'UTF-8';
        insert u1;
        
        User_Task__c utA = New User_Task__c();
        utA.Date__C = System.today();
        utA.Total_tasks__c = 0;      
        insert utA;
        
        List<Task> tasks = new List<Task>{};

        System.runAs(u1) {
        	Task tA = new Task(Subject='TestA1',Status='New',Priority='Normal',CallType='Outbound');
            insert tA; 
        }
        
        List<User> users = [select id,Name from User where IsActive=true];

        List<User_Task__c> utList= [Select ID From User_Task__c where date__c = :System.today()];
        		
        System.assertEquals(2, utList.size());
        
		Test.stopTest();     
	}
}

Can someone please help me how to test schedulable class with method to insert new records.

Thanks,
Jas
