How to set your own Created Date for the inserted salesforce record in test class - Salesforce Spring 16 Release

Until Winter 16, You won't able to set created date for records which you are creating in Test class. By default, Created Date will be the current date while running test.

Beginning from Spring 16, You can set your own custom date as Created Date in test class.

Syntax:

1. setCreatedDate(Id recordId, Datetime createdDatetime);

Sample Code:

1. @isTest
2. private class SetCreatedDateTest {
3.     static testMethod void testSetCreatedDate() {
4.         Account a = new Account(name='myAccount');
5.         insert a;
6.         Test.setCreatedDate(a.Id, DateTime.newInstance(2012,12,12));
7.         Test.startTest();
8.         Account myAccount = [SELECT Id, Name, CreatedDate FROM Account
9.                              WHERE Name ='myAccount' limit 1];
10.         System.assertEquals(myAccount.CreatedDate, DateTime.newInstance(2012,12,12));
11.         Test.stopTest();
12.     }
13. }

Note:

1. All database changes are rolled back at the end of a test.

2. You can’t use this method on records that existed before your test executed. 

3. You also can’t use setCreatedDate in methods annotated with @isTest(SeeAllData=true), because those methods have access to all data in your org.

4. This method takes two parameters—an sObject ID and a Datetime value—neither of which can be null.

How to check list size in visualforce page

Most of peoples wanted to display the table if the list has records. For this you can use the below approach,

Apex Class:

1. public class AccountController
2. {
3.     public List<Account> accList{get; set;}
4.     public AccountController()
5.     {
6.         accList = [SELECT Id, Name FROM Account LIMIT 10];
7.     }
8. }

Visualforce Page:

1. <apex:page controller="AccountController">
2.     <apex:pageBlock title="Account List" >
3.         <apex:outputPanel rendered="{! IF(ISBLANK(accList), false, true) }">
4.             <apex:pageBlockTable value="{!accList}" var="acc" rendered="{!accList.size > 0}">
5.                 <apex:column headerValue="Account Name"> {!acc.Name} </apex:column>
6.             </apex:pageBlockTable>
7.         </apex:outputPanel>
8.     </apex:pageBlock>
9. </apex:page>

Two conditions are checked in the above visualforce page,

Condition 1:

{!IF(ISBLANK(accList), false, true)}

This will ensure to prevent from displaying table in the following conditions,

1. LIST not yet initialized. 

2. LIST has been initialized, but no records.

Condition 2:

{!accList.size > 0}

Table will be displayed only if the LIST contains at least one record.

Important Note:

Please note down the below points as per the salesforce documentation,

To ensure a smooth transition, each critical update has an opt-in period, which ends on the auto-activation date that’s displayed on the Critical Updates page in Setup.

After the opt-in period has passed, the update is automatically activated.

How to test a Restful web services in Salesforce by using Advanced Rest Client chrome app

      The below article will help you to create a basic Rest API class to insert an account record in salesforce by creating a method with @HttpPost annotation. Also this guide will help you to test the functionality by using using Advanced Rest Client chrome app. 

Step 1: 

Create a REST API class with @HttpPost annotation method. 

1. @RestResource(urlMapping='/AccountMapping/*')
2. global with sharing class RESTAccountController {
3. 
   
4. @HttpPost  
5.   global static String createNewAccount(String accountName, String accountNumber) {
6.      System.debug('Account Name: '+accountName);
7.      System.debug('Account Number: '+accountNumber);
8.      try
9.      {
10.          Account acc = new Account();
11.          acc.Name = accountName;
12.          acc.AccountNumber = accountNumber;
13.          insert acc;
14.          return 'Account has been inserted succesfully: '+acc.Id;
15.      }
16.      catch(DMLException de)
17.      {
18.         return de.getDmlMessage(0);
19.      }
20.                
21.      return null;
22.   }
23. }

Note:

The @RestResource annotation is used at the class level and enables you to expose an Apex class as a REST resource.

1. The URL mapping is relative to https://instance.salesforce.com/services/apexrest/

2. URL mapping is case-sensitive

Read this documentation well before setting up urlMapping. 

Step 2: 

Install Advanced Rest Client from the below link,

https://chrome.google.com/webstore/detail/advanced-rest-client/hgmloofddffdnphfgcellkdfbfbjeloo

Note: You can also use Postman tool, if you like.

Step 3:

Create a "Connected App" by referring this documentation.

After you created the "Connected App", Go to Create --> Apps --> Connected App --> Select your connected app which you created.

Your connected app looks like below,

After you created a connected app ensure the app permission is given at profile level. Also Copy the "Consumer Key" and "Consumer Secret" code for authentication in Advance Rest Client.

Step 4:

Open Advanced REST Client app in Chrome and follow the below steps.
