How to Test Salesforce REST API

                   How to Test Salesforce REST API

To Test Salesforce Rest API First we need to create Connected App in Salesforce.Once we created Connected App it will generate consumer or client id and consumer secret.

After that we need to create Access-token using below steps.

1.grant_type=password&client_id=YourClientId&client_secret=YourClientSecret&username=YourUserName&password=YourPassword+securitytoken

EX:

client_id =  3MVG9ZL0ppGP5UrB.7GK_luxRT7StxC8dM37EZzuyrj0LMr_TaiMZatpDKASHUikAvgczZCo1ONfmzhV5LER1

client_secret = 1328342625760846904

username =  username

password=YourPassword+securitytoken

Content-Type : application/x-www-form-urlencoded

To make HTTP Requests we are using https://www.hurl.it/  or SOAP UI tool.

Here we will get response like below format:

{"access_token": "00D28000001xtTR!AQkAQO.ZKKI4ccUpsQLzm.RpgI4HxLuMU8vqrpmpku_DEc3_aHMs9ar60o_l2HR9Vc2cF3IbFS8jC5UDD38h3CmXvBX6ue42","instance_url": "https://ap2.salesforce.com","id": "https://login.salesforce.com/id/00D28000001xtTREAY/00528000005dGo3AAE","token_type": "Bearer","issued_at": "1491551856783","signature": "RxPY7+SXQEyaIzTW3B5c1N/0C3ciwhojKNbULX9Xawo="}

Now we will test Rest WS using above access token.

Sample RestClass:

@RestResource(urlmapping = '/showAccounts/*')

global class RestExample {

   

    @HttpGet

    global static list<account> getAccounts(){

        list<account> lstAccounts = new list<account>();

        RestRequest request = RestContext.request;

        system.debug('request >>>' + request);

        string accName = request.params.get('name');

        system.debug('==accName==='+accName);

        lstAccounts = [select id,name,phone from account where name =: accName];       

        system.debug('===result==='+lstAccounts);

        return lstAccounts;

    }

   

}

Using Below Extensions also we can test REST WSs.

Advanced REST client - Chrome Web Store

Postman - Chrome Web Store

How to disable/enable all validation rules for data loading in Salesforce

How to disable/enable all validation rules for data loading in Salesforce:



1) click Setup, then on the left side, click Develop/Custom Settings.
2) click New and create your settings as hierarchy/public

3) now create a custom field of type Checkbox: click New, select Checkbox, click Next, type the name of the field as “Disable Validation Rules”, default to Unchecked, click Next, then click Save.

4) in the Custom Setting Definition/Your App Settings screen, click Manage to start configuring the setting you just created.

5) click the New button above “Default Organization Level Value”, leave the checkbox “Disable Validation Rules” unchecked and then click Save.

6) click “Back to List”, click the New button at the bottom, select Profile or User then choose the user id or profile that will perform the data loading, then click “Disable Validation Rules” and click Save.

7) now edit the validation rule appending the expression (highlighted below)
&& NOT( $Setup.Your_App_Settings__c.Disable_Validation_Rules__c )

8 ) click Save

9) now the validation rule will only apply if the setting checkbox
Disable Validation Rules is unchecked for your profile/user

10) you can now load data freely and then, later, re-enable all
validation rules for your profile/user by changing the custom
setting.

11) you can use this way of implementing Custom Settings on
triggers too, just use the syntax below:

• Your_App_Settings__c s = Your_App_Settings__c.getInstance( UserInfo.getUserID() );
• if( s.Disable_Validation_Rules__c ) return;

Examples : 

In Trigger : 

trigger AccountTriggerHandler on Account (before insert,before update,after update) {

    Application__c bypassTrigger= Application__c.getInstance( UserInfo.getUserID() );

    if(!bypassTrigger.DisableValidations__c){

        if(trigger.isbefore && trigger.isinsert){

            for(account acc : trigger.new){

                if(acc.phone == null){

                    acc.phone.addError('phone no required');

                }

            }

        }

        

    }

    

}

Validation :

ISBLANK( Phone ) && NOT( Setup.Application__c.DisableValidations__c )

}

Purpose:    1. This is the Trigger Handler class for Account object




public class AccountHandlerClass {

/*******  Sample method 1 *********/

 public static void updateContacts2(map<id,account> newAccountMap){

}

2.write Soql query to Accounts with contact. 

list<account> acc = [select Id,name from Account where Id In (select AccountId from Contact)];

3.if a controller has a series of extensions then which extension will execute first.

If both extension having same method, whichever methods are defined in the “leftmost” extension, or, the extension that is first in the comma-separated list will execute first.

====================================================================

<apex:page standardController="Account" extensions="Extension1,Extension2">

    <apex:form>

        Displaying name from Extensions : "{!Name}"

    

    </apex:form>

</apex:page>

====================================================================

public class Extension1 {    

    public Extension1(ApexPages.StandardController controller){}

    public static string getName(){      

        return 'Prasad';

    }

}

public class Extension2 {      

    public Extension2(ApexPages.StandardController controller){}

  

    public static string getName(){       

        return 'Kalyan';

    }

    

}

4.Transaction Control using SavePoint and Rollback in Salesforce.

SavePoint and Rollback will help us to maintain transaction for DML statement.

Suppose you  have written multiple lines of DML statements in a try block, If any error occurs during DML Operations, the operation will be rolled back to the most recent save point and the entire transaction will not be aborted.

   Savepoint sp;

try{

   sp = Database.setSavepoint();

  

   Account a = new Account();

   a.Name = 'Test Account';

   insert a;

  

   Contact c = new Contact(Account = a.Id);

   c.FirstName = 'Biswajeet';

   c.LastName = 'Samal';

   insert c;

  }

catch(Exception e){

    Database.RollBack(sp);

}

9.How to setup Field Level Security (FLS) for Person Account Fields.

OR
Why I am not able to find list of Person Account fields in Field Level Security (FLS) settings when navigated to fields on Account Object.
Ans :

Field Level Security (FLS) of Person Account fields ar controlled by Contact Fields. So, if you want to setup FLS of Person Account Fields navigate to fields of Contact and it will be reflected on Person Account.

10.In below code snippet , What is your observation and what is going wrong ?

trigger TestBeforeDelete on Lead (before Delete) {

for(Lead l : Trigger.Old)

{

l.addError('error');

}

String msgBody = 'Test Email';

String Subject = 'Test from Cogni Force on Lead';

Messaging.SingleEmailMessage mail = new Messaging.SingleEmailMessage();

String[] toAddresses = new String[] {'abc@gmail.com'};

mail.setToAddresses(toAddresses);

mail.setReplyTo('abc@gmail.com');

mail.setSenderDisplayName('Cogniforce Test Simulator');

mail.setSubject(Subject);

mail.setPlainTextBody(msgBody);

mail.setHTMLBody(msgBody);

Messaging.sendEmail(new Messaging.SingleEmailMessage[] { mail });

}

Ans :

It will not send any email. Because “adderror” prevents all transactions from committing including emails.

10.How To Start Loading Data From 101 Row Of The CSV File In Data Loader?


In Dataloader Settings we need to specify Start Row no:

11.Calling future method from batch class?


Future method cant be called from future or Batch.

recommend the use of System.Queueable call instead of @Future. You can create a class that is constructed with any kind of argument that you want to hand in, like so:

public class DeferredHandler implements System.Queueable{

    public void execute(System.QueueableContext objContext)    {

        //do your @Future stuff here 

    }

}

And invoke him from inside your batch like this:

//defer stuff

System.Queueable job = new DeferredHandler(key2val);

System.enqueueJob(job);
