Oron, you can learn how to write the test coverage from the below link:
https://developer.salesforce.com/docs/atlas.en-us.apexcode.meta/apexcode/apex_qs_test.htm

For your case you will have create an Account/Contact(s)/Opportunity test data, as soon as you will insert the opportunity the trigger will fire and will give you the code coverage.

Just be careful as I can see in your code you got select queries running inside the for loop, which is not good practice and will hit the limits for bulk uploads.

As a best practice try not to have select or DML inside the loops and use more of List/Set/Maps (collections)

Hi Oron,

Try with below cod eit will definitly help !
  
@isTest
public class TestPrimaryContactRole{
  public static testMethod void unitTest(){
     Opportunity opp=new opportunity();
         opp.Name='TestOpportunity';
         opp.StageName='Prospecting';
         opp.CloseDate=System.Today();
		 //Add any mandatory field incase 
         Insert opp;
		 opp=[SELECT id,StageName FROM Opportunity WHERE Id=:opp.Id];
		 System.assertEquals(opp.stageName,'Prospecting');
     Contact con=new Contact();
         con.LastName='LastName';
         con.Email='Test@gmail.com';
         con.Phone='8906756432';
         con.Passport_Num_contact__c='Ahkju786TFs';
         con.Local_ID_contact__c='TestCon';
		 //Add any mandatory field incase 
         insert con;
		 con=[SELECT id ,lastName FROM Contact WHERE Id=:con.Id];
		 System.assertEquals(con.LastName,'LastName');
     OpportunityContactRole oppconrole=new OpportunityContactRole();
        oppconrole.IsPrimary=true;
        oppconrole.ContactId=con.Id;
        oppconrole.Opportunityid=opp.Id;
        Insert oppconrole;
        Test.startTest();
        update opp;
        Test.stopTest();
  
  }
}

Check the below link it will help you to write better test class in future .
