Common test utility classes are public test classes that contain reusable code for test data creation.The TestDataFactory/ testutility class is a special type of class — It is a public class that is annotated with @isTest and and as such, are excluded from the organization code size limit and execute in test context and can be accessed only from a running test.
Test utility classes/TestDataFactory contain methods that can be called by test methods to perform useful tasks, such as setting up test data.
Step 1:- Create TestDataFactory / Test utility
@isTest
public with sharing class TestDataFactory
{
/**
* ********************************************************
* This method is test data for create Lead
* ********************************************************
*/
public static Lead createLead(Boolean doInsert)
{
Lead newLead = new Lead() ;
newLead.FirstName = 'Cole';
newLead.LastName = 'Swain';
newLead.Company = 'BlueWave';
newLead.Status = 'contacted';
if(doInsert){
insert newLead;
}
return newLead;
}
public static Void convertLead(Lead newLead )
{
database.leadConvert lc = new database.leadConvert();
lc.setLeadId(newLead.id);
leadStatus convertStatus = [SELECT Id, MasterLabel FROM LeadStatus WHERE IsConverted=true LIMIT 1];
lc.setConvertedStatus(convertStatus.MasterLabel);
Database.LeadConvertResult lcr = Database.convertLead(lc);
System.assert(lcr.isSuccess());
lc.setOpportunityName('Cole Swain');
}
/**
* ******************************************************
* This method is test data for create Account
* ******************************************************
*/
public static Account createAccount(Boolean doInsert)
{
Account acc = new Account();
acc.Name = 'Test Account';
if(doInsert){
insert acc;
}
return acc;
}
/**
* *******************************************************
* This method is test data for create contact object
* *******************************************************
*/
public static Contact createContact(Boolean doInsert)
{
return createContact(doInsert, createAccount(true).Id);
}
public static Contact createContact(Boolean doInsert, Id accId)
{
Contact con = new Contact();
con.AccountId = accId;
con.FirstName = 'FirstName';
con.LastName = 'LastName';
con.Email = 'FirstName@test.com' + Math.floor(Math.random() * 1000);
if(doInsert)
{
insert con;
}
return con;
}
/**
* ***********************************************************
* This method is test data for create Opportunity object
* ***********************************************************
*/
public static Opportunity createOpportunity(Boolean doInsert, Id accId)
{
Opportunity oppt = new Opportunity(Name ='New mAWS Deal',
AccountID = accId,
StageName = 'Customer Won',
Amount = 3000,
CloseDate = System.today()
);
if(doInsert)
{
insert oppt;
}
return oppt;
}
/**
* ************************************************************
* This method is test data for create Case object
* ************************************************************
*/
public static Case createCase(Boolean doInsert )
{
Case cas = new Case(Status ='New', Priority = 'Medium', Origin = 'Email');
if(doInsert)
{
insert cas ;
}
return cas ;
}
}
Step 2:- How to Use TestDataFactory / Test utility
@isTest
private class MyTestClass
{
static testmethod void myUnitTest()
{
Lead leadObj = TestDataFactory.createLead(true);
Account accObj = TestDataFactory.createAccount(true);
Contact contObj = TestDataFactory.createContact(true,accObj.id);
Opportunity oppObj = TestDataFactory.createOpportunity(true,accObj.id);
Case caseObj = TestDataFactory.createCase(true);
}
// If you want to edit data according to apex class then try like below
static testmethod void myUnitTest1()
{
Lead leadObj = TestDataFactory.createLead(false); // pass false
leadObj.LastName ='MyName';
insert leadObj ;
Account accObj = TestDataFactory.createAccount(false);
accObj.Name ='MyName';
insert accObj;
}
}
