Hi All,
I created a trigger, so that when a new event is created in Public Calendar a new CalendarEV record will be created automatically. I got error message after running test class that missing required fields, so no code coverage at all. I noticed that both Start and End fields in Event object are required Date/Time fields, so I wonder how to create Date/Time in test class for these two fields so that an event can be created and fire the trigger. Please help.

Error message: System.DmLException: insert failed. First exception on row 0; First error, Required field missing
Stack Trace: Class.CalendarEVTest.insertNewCalendarEV: Line11, colum 1

trigger CalendarEV on Event (after insert) {
List<Event> Events = new List<Event>();
   for (Event e : Trigger.new) {
           if (e.Subject != null ) {
               CalendarEV__c C = new CalendarEV__c();
               c.Name = e.Subject;
               c.Start__c = e.StartDateTime;
               c.End__c = e.EndDateTime;
               c.Location__c = e.Location;
               c.Description__c = e.Description;
                    
              insert C;
        }
    }
   }


@isTest
public class CalendarEVTest
{
    static testMethod void insertNewCalendarEV()
    {
        Test.StartTest();
        Event e = new Event();
        e.Subject = 'Test Event';
        e.Location = 'Test Location';
        e.Description = 'Test Description'; 
        insert e;
        Test.StopTest();
        System.assertEquals ('Test Event', e.Subject);
    }
}
