apex trigger unit test

Hi 
Could someone help me write a apex unit test for the following trigger. I am new to apex. 
trigger acceptedspeakerroles on CampaignMember (after insert, after update, after delete, after undelete) {
Map<Id,Contact> contacts = new Map<Id,Contact>();
  if(Trigger.new<>null)
    for(CampaignMember c:Trigger.new)
      if(c.ContactId<>null)
        contacts.put(c.ContactId,new Contact(id=c.ContactId));
  if(Trigger.old<>null)
    for(CampaignMember c:Trigger.old)
      if(c.ContactId<>null)
        contacts.put(c.ContactId,new Contact(id=c.ContactId));
  update contacts.values();
}


Many Thanks
Conor

Hi Conor,

Try the following code, it may be helpful for you: 
@IsTest
public class acceptedspeakerroles_Test {
    @IsTest
    public static void method1(){
        
        Account acct = new Account ();
        acct.Name='test';
        insert acct;

        Contact co1 = new Contact();
        co1.FirstName = 'First';
        co1.LastName = 'Last';
        co1.AccountId = acct.Id;
        insert  co1;

        Campaign ca1 = new Campaign();
        ca1.Name = 'Testcampaign';
        ca1.IsActive = TRUE;
        insert ca1;

        CampaignMember m1 = new CampaignMember();
        m1.ContactId = co1.Id; 
        m1.CampaignId = ca1.Id;
        
        insert m1;
        m1.Status ='Attended';
        update m1;
    }
}
