       for (Integer i = 0; i < numOpps; i++) {
           Opportunity opp = new Opportunity(

               AccountId = accountId,
               Amount = amount,
               CloseDate =,

       insert userRole;
       String uniqueEmail = 'Cpt.Awesome' + + '';

           Username = uniqueEmail,
           CompanyName = 'Testing Co',

(B) Class Name: DataGenerationTest

private class DataGenerationTest {
  static void dataCreation() {
      Account account = TestFactory.getAccount('Muddy Waters Inc.', true);
      Contact contact = TestFactory.getContact(account.Id, 'Muddy', 'Waters', true);
      Opportunity opp = New Opportunity();

      opp.CloseDate =;
      opp.StageName = 'Prospecting';
      insert opp;
  static void testBruteForceAccountCreation() {
      List<Account> accts = new List<Account>();
          accts = [SELECT Id FROM Account];
      Assert.areNotEqual(accts.size(), 0,'Was expecting to find at least one account created on the Test Setup');
  static void testUseTestFactoryToCreateAccountsWithContacts() {
      List<Account> accts;
      List<Contact> contacts;
          accts = [SELECT Id FROM Account];
          contacts = [SELECT Id FROM Contact];
      Assert.isNotNull(accts, 'Was expecting to find at least one account created');
      Assert.areEqual(contacts.size(), 6, 'Was expecting to find 6 contacts');
      Assert.areNotEqual(accts.size(), contacts.size(), 'Was expecting there to be a different number of account and contacts');
  static void testAtTestSetupMethodsRule() {
      List<Opportunity> opps = [SELECT Id, AccountId FROM Opportunity];
      Assert.areEqual(1, opps.size(), 'Expected test to find a single Opp');
