Here is the test class for your code,

@isTest
public class OpportunityTriggerHandlerTest
{
static testMethod void insertOpportunity()
{

List<Opportunity> oppRecordList= new List<Opportunity>();

Contact cnt=new Contact(LastName='Test Contact');
insert cnt;

for(integer i=0;i<=200;i++)
{
oppRecordList.add(new Opportunity(Name='Test',CloseDate=System.today(),StageName='Closed Won',Buyer__c=cnt.id));
}
insert oppRecordList;


OpportunityTriggerHandler oppInstance=new OpportunityTriggerHandler();
oppInstance.createNewContact(oppRecordList);
}
}

Try below code :-

@isTest
public class OpportunityTrigger_test{
    static testMethod void MyUnitTest(){
        opportunity opp= new Opportunity(); 
        opp.Name = 'Test Opp'; // Populate all the fields required to insert an opportunity record
        opp.CloseDate = system.today();
        Opp.StageName = 'Prospecting';

        insert opp;


}
}

If this helps,please mark this as best answer to help others :)
