Declarative Approach Programmatic Approach

Declarative before Programmatic

Use declarative features when possible:• Quicker to build• Easier to maintain and debug• Possible addition of new features• Do not count against governor limits

For example:• Will a workflow suffice instead of a trigger?• Will a custom layout work instead of

Visualforce?

Unit TestingCode which asserts that existing logic is operating correctly

• Code to test code

• Tests can mirror user expecations

• System Asserts increase predictability

• Line Coverage increase predictability

Unit Testing

Unit Testing in Apex

Built in support for testing– Test Utility Class Annotation

– Test Method Annotation

– Test Data build up and tear down

Unit test coverage is required– Must have at least 75% of code covered

Why is it required?

Basic Unit Test Structure@isTest

public class TestClase{

@isTest static void testCase(){

//setup test data

List<Contact> contacts = ContactFactory.createTestContacts();

//process / perform logic

EvaluateContacts.process(contacts);

//assert outcome

System.assertEquals(EvaluateContacts.processed.size(),contacts.size());

}

}

Testing Permissions

//Set up user

User u1 = [SELECT Id FROM User WHERE Alias='auser'];

//Run As U1

System.RunAs(u1){

//do stuff only u1 can do

}

Static Resource Data

List<Invoice__c> invoices = Test.loadData(Invoice__c.sObjectType, 'InvoiceData');

update invoices;

Testing Context and Asynchronous Behavior

// this is where the context of your test begins

Test.StartTest();

//execute future calls, batch apex, scheduled apex

UtilityRESTClass.performCallout();

// this is where the context ends

Text.StopTest();

System.assertEquals(a,b); //now begin assertions

Apex Triggers

• Event Based Logic

• Associated with Object Types

• Before or After:• Insert

• Update

• Delete

• Undelete

Controlling Flow

trigger LineItemTrigger on Line_Item__c

(before insert, before update) {

//separate before and after

if(Trigger.isBefore) {

//separate events

if(Trigger.isInsert) {

System.debug(‘BEFORE INSERT’);

DelegateClass.performLogic(Trigger.new);

Static Flags

public with sharing class AccUpdatesControl {

// This class is used to set flag to prevent multiple calls

public static boolean calledOnce = false;

public static boolean ProdUpdateTrigger = false;

}

Chatter Triggers

trigger AddRegexTrigger on Blacklisted_Word__c (before insert, before update)

{

for (Blacklisted_Word__c f : trigger.new)

{

if(f.Custom_Expression__c != NULL)

{

f.Word__c = '';

f.Match_Whole_Words_Only__c = false;

f.RegexValue__c = f.Custom_Expression__c;

}

}

}

LUNCHLunchDown the hall

Scheduled ApexInterface for scheduling Apex jobs

Schedulable Interface

global with sharing class WarehouseUtil implements Schedulable {

//General constructor

global WarehouseUtil() {}

//Scheduled execute

global void execute(SchedulableContext ctx) {

//Use static method for checking dated invoices

WarehouseUtil.checkForDatedInvoices();

}

System.schedule('testSchedule','0 0 13 * * ?',new WarehouseUtil());Via Apex

Via Web UI

Schedulable Interface

Batch ApexApex interface for processing large datasets asynchronously

Apex Batch Processing

Governor Limits– Various limitations around resource usage

Asynchronous processing– Send your job to a queue and we promise to run it

Can be scheduled to run later– Kind of like a cron job

Batchable Interface

global with sharing class WHUtil implements Database.Batchable<sObject>

{

global Database.QueryLocator start(Database.BatchableContext BC)

{ //Start on next context }

global void execute(Database.BatchableContext BC,

List<sObject>scope)

{ //Execute on current scope }

global void finish(Database.BatchableContext BC)

{ //Finish and clean up context }

}

Unit Testing Asynchronous Apex

//setup test data

Test.StartTest();

System.schedule('testSchedule','0 0 13 * * ?',new,WarehouseUtil());

ID batchprocessid = Database.executeBatch(new WarehouseUtil());

Test.StopTest();

//assert outcomes

Apex IntegrationUsing Apex with third party systems

Apex HTTPpublic FlickrList getFlickrData(string tag) {

HttpRequest req = new HttpRequest();

req.setMethod('GET');

req.setEndpoint('http://api.flickr.com/services/feeds/photos_public.gne?

nojsoncallback=1&format=json&tags='+tag);

HTTP http = new HTTP();

HTTPResponse res = http.send(req);

return

(FlickrList)JSON.deserialize(res.getBody().replace('\\\'',''),FlickrList.class);

}

Apex REST

@RestResource(urlMapping='/CaseManagement/v1/*')

global with sharing class CaseMgmtService

{

@HttpPost

global static String attachPic(){

RestRequest req = RestContext.request;

RestResponse res = Restcontext.response;

Id caseId = req.requestURI.substring(req.requestURI.lastIndexOf('/')+1);

Blob picture = req.requestBody;

Attachment a = new Attachment (ParentId = caseId,

Body = picture,

ContentType = 'image/

Unit Tests: Mock HTTP Endpoints

@isTest

global class MockHttp implements HttpCalloutMock {

global HTTPResponse respond(HTTPRequest req) {

// Create a fake response

HttpResponse res = new HttpResponse();

res.setHeader('Content-Type', 'application/json');

res.setBody('{"foo":"bar"}');

res.setStatusCode(200);

return res;

}

}

Unit Tests: Mock HTTP Endpoints

@isTest

private class CalloutClassTest {

static void testCallout() {

Test.setMock(HttpCalloutMock.class, new MockHttp());

HttpResponse res = CalloutClass.getInfoFromExternalService();

// Verify response received contains fake values

String actualValue = res.getBody();

String expectedValue = '{"foo":"bar"}';

System.assertEquals(actualValue, expectedValue);

}

}

CRUD/Q Functionality Data Model Components JavaScript Framework Friendly

Interacting with Apex

• ActionFunction allows direct binding of variables

• ActionFunction requires ViewState

• JavaScript Remoting binds to static methods

• JavaScript Remoting uses no ViewState

• Transient, Private and Static reduce Viewstate

CanvasFramework for embedding third party apps into Salesforce

How Canvas Works

• Only has to be accessible from the user’s browser

• Authentication via OAuth or Signed Response

• JavaScript based SDK can be associated with any language

• Within Canvas, the App can make API calls as the current user

• apex:CanvasApp allows embedding via Visualforce

Any Language, Any Platform

Using publisher.js

Sfdc.canvas.publisher.subscribe({

name: "publisher.post",

onData: function(e) {

// fires when the user hits 'Submit'

postToFeed();

}

});

Sfdc.canvas.publisher.publish({

name: "publisher.close",

payload: { refresh:"true"}

});
