Unit 2: Get Hands-On With Apex Assertions

Step 1: Create a new Playground or use the previous one. But don't use developer org for this.

Step 2: Open Developer Console and create a new class named as Test Factory. Copy the below code and paste it into the class and Save it.

	@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 3: Create a new class named as DataGenerationTest and Copy the below code and paste it into the class and Save it.

	@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');
	}
	}
