Test Class needed for my trigger. HELPPPP

i am a beginner i managed to create the below trigger to update the campaign member status before lead update. .  

 

can any one help me writing a test class for it.

 

thanks in advance for your help.

 

trigger UpdateMemberStatus on Lead ( before insert ,before update) {

Lead[] leads = Trigger.new;

for (Lead l:leads){

List<CampaignMember> status = new List<CampaignMember>();

// select the status for the most recent campaign for that lead

status = [SELECT status FROM CampaignMember  WHERE leadId = :l.id order by id desc limit 1];

// make sure the lead is assigned to the campaign.

if (!status.isEmpty())

{

status[0].status = l.outcome__c;

update status;

}

}

first of all this trigger must be bulkafied!  (make all SOQL queries outside of loops.)

 

secondly, a test class just contains any action that fires the trigger.

in this case create a fake lead definition, insert it (make sure the status is not empty), update it, and check the results with an assertion.

 

even something as simple as the following will work...

 

public class TestClass {
    public static testmethod void t1() {
     Lead abc = new Lead(fields = values);

     insert abc;

     

     status = [select status from...];

     assertequals(status[0].status,abc.outcome__c);

  }

}
