Inserting test data using a list to reduce the number of DMLs

Question

I got the below test class,

@isTest
public with sharing class CategoryHelperTest {

        private static boolean testDataCreated = false;
        private static Scheme__c ss;
        private static Scheme__c ss2;
        private static Scheme__c ss3;
        private static Scheme__c ss4;
        private static Scheme__c ss5;
        private static Scheme__c ss6;

public static void tester(){
        ss = new Scheme__c(Name = 'TestScheme', Description__c = 'TestScheme');
        insert ss;
        ss2 = new Scheme__c(Name = 'TestScheme', Description__c = 'TestgScheme2');
        insert ss2;
        ss3 = new Scheme__c(Name = 'TestScheme', Description__c = 'TestScheme3');
        insert ss3;
        ss4 = new Scheme__c(Name = 'TestScheme', Description__c = 'TestScheme4');
        insert ss4;
        ss5 = new Scheme__c(Name = 'TestScheme', Description__c = 'TestScheme5');
        insert ss5;
        ss6 = new Scheme__c(Name = 'TestScheme', Description__c = 'TestScheme6');
        insert ss6;

I want to use a list for schemes, instead inserting data one by one. How can I get this done using a List ?

Answer 1

Haven't you try populating a list and inserting?

public static void tester(){
  List<Scheme__c> insertList = new List<Scheme__c>();
  insertList.add(new Scheme__c(Name = 'TestScheme', Description__c = 'TestScheme'));
  insertList.add(new Scheme__c(Name = 'TestScheme', Description__c = 'TestScheme2'));
  insertList.add(new Scheme__c(Name = 'TestScheme', Description__c = 'TestScheme3'));
  insertList.add(new Scheme__c(Name = 'TestScheme', Description__c = 'TestScheme4'));
  insertList.add(new Scheme__c(Name = 'TestScheme', Description__c = 'TestScheme5'));

  insert insertList;

}
