→    Get Hands-On With Apex Assertions

Launch the org you’ll use for the hands-on challenge, then do the following prework.

Step: 1

Now, as mentioned in trailhead challenge, we need to create one apex class.

To open the Developer Console from Salesforce Classic:

1. Click Your Name.
2. Click Developer Console.

To open the Developer Console from Lightning Experience:

1. Click the quick access menu ().
2. Click Developer Console.

Follow below steps in developer console
~ File > New > Apex Class

Step: 2

As mentioned in trailhead challenge, enter 'Apex Class' name and click 'OK' button.
    Class Name: TestFactory

Step: 3 

Copy below mentioned code and paste in developer console and 'Save' this apex class.

@isTest
public class TestFactory {
   public static Account getAccount(String accountName, Boolean doInsert) {
       Account account = new Account(Name = accountName);
       if (doInsert) {
           insert account;
       }
       return account;
   }
   public static Contact getContact(Id accountId, String firstName, String lastName, Boolean doInsert){
       Contact contact = new Contact(
           FirstName = firstName,
           LastName = lastName,
           AccountId = accountId
       );
       if (doInsert) {
           insert contact;
       }
       return contact;
   }
   public static void generateAccountWithContacts(Integer numContacts) {
       Account account = getAccount('default account ltd', true);
       List<Contact> contacts = new List<Contact>();
       for (Integer i = 0; i < numContacts; i++) {
           String firstName = 'Contact';
           String lastName = 'Test' + i;
           contacts.add(getContact(account.Id, firstName, lastName, false));
       }
       insert contacts;
   }
   public static Opportunity[] generateOppsForAccount(ID accountId, Decimal amount, Integer numOpps){
       List<Opportunity> oppsForAccounts = new List<Opportunity>();
       for (Integer i = 0; i < numOpps; i++) {
           Opportunity opp = new Opportunity(
               Name = 'Account ' + i,
               AccountId = accountId,
               Amount = amount,
               CloseDate = Date.today().addDays(5),
               StageName = 'Prospecting'
           );
           oppsForAccounts.add(opp);
       }
       return oppsForAccounts;
   }
   public static User generateUser(String profileName) {
       UserRole userRole = new UserRole(
           DeveloperName = 'TestingTeam',
           Name = 'Testing Team'
       );
       insert userRole;
       String uniqueEmail = 'Cpt.Awesome' + DateTime.now().getTime() + '@th.example.com';
       User userForInsert = new User(
           ProfileId = [SELECT Id FROM Profile WHERE Name = :profileName].Id,
           LastName = 'lastName',
           Email = uniqueEmail,
           Username = uniqueEmail,
           CompanyName = 'Testing Co',
           Title = 'Captain',
           Alias = 'alias',
           TimeZoneSidKey = 'America/Los_Angeles',
           EmailEncodingKey = 'UTF-8',
           LanguageLocaleKey = 'en_US',
           LocaleSidKey = 'en_US',
           UserRoleId = userRole.Id
       );
       insert userForInsert;
       return userForInsert;
   }
}

Step: 4  

Now follow step 1 & 2 again and create another apex class.

    Class Name: DataGenerationTest

Copy below mentioned code and paste in developer console and 'Save' this apex class.

@isTest
private class DataGenerationTest {
  @testSetup
  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.Name = 'Long lost record';
      opp.AccountId = account.Id;
      opp.CloseDate = Date.today().addDays(14);
      opp.StageName = 'Prospecting';
      insert opp;
  }
  @isTest
  static void testBruteForceAccountCreation() {
      List<Account> accts = new List<Account>();
      Test.startTest();
          accts = [SELECT Id FROM Account];
      Test.stopTest();
      assert.isTrue(accts.size() > 0, 'Was expecting to find at least one account created on the Test Setup');
  }
  @isTest
  static void testUseTestFactoryToCreateAccountsWithContacts() {
      List<Account> accts;
      List<Contact> contacts;
      TestFactory.generateAccountWithContacts(5);
      Test.startTest();
          accts = [SELECT Id FROM Account];
          contacts = [SELECT Id FROM Contact];
      Test.stopTest();
      assert.isTrue(accts.size() > 0, 'Was expecting to find at least one account created');
      assert.isTrue(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');
  }
  @isTest
  static void testAtTestSetupMethodsRule() {
      List<Opportunity> opps = [SELECT Id, AccountId FROM Opportunity];
      assert.areEqual(1, opps.size(), 'Expected test to find a single Opp');
  }
}
