Step by Step Salesforce Tutorial – Creating Trigger and Test cases – 6 of 6

  1. Creating custom object
  2. Creating Fields
  3. Creating Tab and Validation Rule
  4. Creating Email Template
  5. Creating Workflow rule
  6. Creating Trigger and Test cases

This is the last tutorial in series and we will see that how to create a Trigger and Test Cases in salesforce.

A trigger is an Apex script that executes before or after specific data manipulation language (DML) events occur, such as before object records are inserted into the database, or after records have been deleted.

Triggers are stored as metadata in Salesforce.com. A list of all triggers in your organization is located at SetupDevelopApex Triggers. In addition to this list, triggers are associated and stored with specific objects.

To define a trigger:

  1. For a standard object, click SetupCustomize, click the name of the object, then click Triggers.For a custom object, click SetupCreateObjects and click the name of the object.For campaign members, click SetupCustomizeCampaignsCampaign MemberTriggers.For case comments, click SetupCasesCase CommentsTriggers.

    For email messages, click SetupCasesEmail MessagesTriggers.

  2. In the Triggers related list, click New.
  3. Click Version Settings to specify the version of Apex and the API used with this trigger. If your organization has installed managed packages from the AppExchange, you can also specify which version of each managed package to use with this trigger. Generally, you should use the default values for all versions. This associates the trigger with the most recent version of Apex and the API, as well as each managed package. You can specify an older version of a managed package if you want to access components or functionality that differs from the most recent package version. You can specify an older version of Apex and the API to maintain specific behavior.
  4. Select the Is Active checkbox if the trigger should be compiled and enabled. Leave this checkbox deselected if you only want to store the script in your organization’s metadata. This checkbox is selected by default.
  5. In the Body text box, enter the Apex for the trigger. A single trigger can be up to “1 million” characters in length.

Read this URL for Governor limit reference.

To define a trigger, use the following syntax:

trigger triggerName on ObjectName (trigger_events) {
   code_block
}

where trigger_events can be a comma-separated list of one or more of the following events:

  • before insert
  • before update
  • before delete
  • after insert
  • after update
  • after delete
  • after undelete

So, lets start with creating trigger.

I want that duplicate student should not be created on the basis of Email id. we can achieve this by other way also, like during creation of email field, we can specify it as unique field.

Open eclipse and right click on salesforce project and select Create new Trigger, as shown in below image

Creating Trigger in Salesforce using force.com IDE
Creating Trigger in Salesforce using force.com IDE

As you can see, to create trigger we have to select the Apex version and operations in wizard.

During Trigger creation, keep in mind that it may be required in bulk operations so governor limit may be problem.

So instead of getting query for all triggers individually, I created an array and after that created a set of email entered for all records, and loop through all records invidually and checked for duplicity.
Only one SOQL is fired instead of all triggers individually and thus can work for bulk insert.

For SOQL Best Practice refer :
http://wiki.developerforce.com/index.php/Best_Practice:_Avoid_SOQL_Queries_ Inside_FOR_Loops

trigger DuplicateStudentCheck on Student__c (before insert) {

       //Get all Student__c related to the incoming Student records in a single SOQL query.
       Student__c[] studentsList = Trigger.new;
       Set emailSet = new Set();
       for(Student__c s : studentsList)
       {
       	emailSet.add(s.Email__c);
       }

       //Get list of duplicate Students
       List duplicateStudentList = [Select s.Name, s.Email__c From Student__c s
where s.Email__c IN :emailSet];

       Set duplicateEmailIds = new Set();

       for(Student__c s : duplicateStudentList)
       {
       	duplicateEmailIds.add(s.Email__c);
       }

       for(Student__c s : studentsList)
       {
       	    if(duplicateEmailIds.contains(s.Email__c))
       	    {
       	    	s.Email__c.addError('Record already exist with same email Id');
       	    }
       }
}

Note: You can add, edit, or delete Apex using the Salesforce.com user interface only in a Developer Edition organization, a Salesforce.com Enterprise Edition trial organization, or sandbox organization. In a Salesforce.com production organization, you can only make changes to Apex by using the Metadata API deploy call, the Force.com IDE, or theForce.com Migration Tool. The Force.com IDE and Force.com Migration Tool are free resources provided by salesforce.com to support its users and partners, but are not considered part of our Services for purposes of the salesforce.com Master Subscription Agreement.

Test Cases in Salesforce :


Test case integral part of code developement.

  • You must have at least 75% of your Apex scripts covered by unit tests to deploy your scripts to production environments. In addition, all triggers should have some test coverage.
  • Salesforce.com recommends that you have 100% of your scripts covered by unit tests, where possible.
  • Calls to
    System.debug are not counted as part of Apex code coverage in unit tests.

So, here we are going to create Test Case for trigger which we have written:

@isTest
private class TestTriggers {

    static testMethod void myUnitTest() {
        Student__c s = new Student__c();
        s.Name = 'Om Test';
        s.l_Name__c = 'LastName';

        Course__c c = new Course__c();
        c.Name = 'SFDC';
        c.Fees__c = 2000;
        insert c;

        s.Course__c = c.Id;
        s.Installment_1__c = 2000;
        s.Email__c = 'admin@JitendraZaa.com';
        try
        {
        	insert s;
        }
        catch(System.DMLException e)
        {
        	System.assert(e.getMessage().contains('Record already exist with same email Id'));
        }
    }
}

To run the test case from Eclipse, right click on test class as shown in below image:

Run Test Case using Eclipse in Salesforce
Run Test Case using Eclipse in Salesforce

The output of the test case, Test coverage result:

Test Coverage result Eclipse in Salesforce
Test Coverage result Eclipse in Salesforce

Run test cases from salesforce.com browser:

click SetupDevelopApex Classes, click the name of the class, then click Run Test. If your class calls another class or causes a trigger to execute, those Apex scripts are included in the total amount used for calculating the percentage of code covered.

To run all the unit tests in your organization, click SetupDevelopApex Classes, then click Run All Tests.

    Hi, thanks for your post, it’s really helpful especially with newbies like me. How come my addError method doesn’t come up with it should’ve done?
    here’s the error message every time i try my code

    Apex trigger ErrorDuplicateOutput caused an unexpected exception, contact your administrator: ErrorDuplicateOutput: execution of BeforeInsert caused by: System.FinalException: SObject row does not allow errors: Trigger.ErrorDuplicateOutput: line 11, column 5

    here’s my code where I compiled with no errors,

    trigger ErrorDuplicateOutput on Account (before insert, before update)
    {
    List accList =new List();
    Set b = new Set{‘Express Logistics and Transport’,’Edge Communications’};
    accList = [Select Id, Name FROM Account Where Name in: b];

    for (Account acc : accList)
    {
    if (b.contains(acc.Name))
    {
    acc.Name.addError(”);
    }
    }
    update accList;
    }

    your help will be very much appreciated!

    Hi Cloud-Ling,
    Please try this:

    trigger ErrorDuplicateOutput on Account (before insert, before update)
    {
    List accList = Trigger.New;

    Set b = new Set{‘Express Logistics and Transport’,’Edge Communications’};

    for (Account acc1 : accList)
    {
    if (b.contains(acc1.Name))
    {
    acc1.Name.addError(‘This is error Message’);
    }
    }
    update accList;
    }

    /*
    * You cannot add error message in existing object, you can add message on object on which operation is performed.
    */

    no_of_openings__c=Remainings__c-1; how do i proceed im a newbie

    Hi Omni,
    If Both object are in relation then u can use “before Trigger” on object (position).

      hi all, i am not a coder at all but consider myself trainable 😉 i am looking to update a field in Opportunity object by copying data from a field in the related account object. I have been struggling with it for a while now. Any help will be highly appreciated. Thanks

      1. JitendraZaa Avatar
        JitendraZaa

        You can try to create Formula field. Opportunity can access all fields of its parent Account using formula field.

        1. Sangeeta Bhatia Avatar
          Sangeeta Bhatia

          yes that would have been the solution but unfortunately cant do that because we dont want to lock it down. This opportunity field should take the value from another field on accounts object on insert should still be editable so cant do formula field

          1. JitendraZaa Avatar
            JitendraZaa

            So, you can create Workflow Rule when Opportunity get created. And use field update. WHile updating field get value from Account record.

    {
    ps.Remainings__c = ps.Openings__c – 1;
    }
    update ps;

    }

    nd the error i get isError: Compile Error: expecting a right parentheses, found ‘status__c’ at line 5 column 17

    1. Jitendra Zaa Avatar

      Hi Priya,
      Instead of double quotes (“) , use single Quotes (‘)
      OR
      in SOQL query use escape sequence – instead of (‘) use (’)

    1. Jitendra Zaa Avatar

      Yes,
      Example –

    I am facing one issue. I want to show trigger error message as html for example. I have following code

    c.addError(‘cannot be rejected through this screen.click < a href="#" rel="nofollow" >here< /a > to Approve/Reject’);

    But it shows as normal text without any hyperlink.

    1. Jitendra Zaa Avatar

      Hi Himanshu,
      It works perfectly. Check below code snap:

      trigger AddLinkInError on Student__c (before insert) {
      Student__c[] studentsList = Trigger.new;
      for(Student__c s : studentsList )
      {
      s.adderror('< a href = ' www.JitendraZaa.com ' > This is Test < / a >. ');
      }
      }

    @58580936bae722b65524173157e34bc3:disqus in looking at your code, I’m fairly certain that if I insert two students with the same email address, in the same batch, it will allow them both to be inserted

      Hey Michael,
      Thanks for reviewing the code.
      I have tested code and its working fine. Any reason or bug you find in above code?

      1. Michael Gallagher Avatar

        Hi Jitendra,
        I’m referring to batch DML, for example something like:insert new Student__c[]{new Student__c(Email__c=’notInDatabase@ notInDatabase.com’), new Student__c(Email__c=’notInDatabase@ notInDatabase.com’)};
        Both student records will be inserted into the database at the same time, as part of the same batch, with duplicate email addresses. See what I mean now?
        Regards,
        Mike

          Yeah.. You are right. I am comparing with existing records only and skipped the condition to check duplicate email Id within batch.

          Thank you so much for your time.

      Hi,
      Either you can add error message at field level or object level.

      Your code explains the field level, below example is at object level:

      trigger test on Account (before insert) {trigger.new[0].addError(‘Nice try’);}

      Hi Amitendra,
      There must be lookup field in Child Object for Parent.
      If its not there then it possible that they are using custom VF page.
      But i am sure that there is lookup field in child object. You can send me the screen shot, then i can answer in better way.

        Amitendra Dixit

         Thanks Jitendra for your information.

        I have solved this problem. Actually there was a object which had lookup with RelationShip Group object and master Details with other object. Therefore it is happen, without direct relationship. Relations between object like this image.

        If any option please tell me …

    I have created around 70 leads with the for our company’s client.
    Now if i want can i set-up a remainder or alert wherein i get a alert or remainder popup to update the status with the latest status,or for that matter even if i have to follow-up remainder or alert mechanism.

      Hi Smita,
      There are lots of ways but i am explaining the easiest way in which no Apex involved.
      Steps:
      1: Create temp field of checkbox type. Dont add this field on any page layout, it should be hidden.
      2.Create workflow rule to update (toggle) that field.
      3.Create other time dependent workflow rule which will check last modify date with current date. if record not modified in last 10 days then send email.

      Note : For existing leads, you will need to update ll the leads using apex.

    The trigger is to create extra assets when certain types of Opportunities are closed. The Trigger seems to run fine but I really have no idea how to start writing test cases… In order for these Opportunities to close, the Account needs to have the following completed (I’ve included some example data – They are picklists so need to be specif amounts):
    a.TurnoverBand__c = ‘<£10 million';
    a.Joining_Fee__c = '£1,920';
    a.Annual_Subscription__c = '£1,320';

    Trigger as follows:

    trigger CreateInclusiveAssetonMembershipWon on Opportunity (after insert, after update)
    {
    for(Opportunity o: trigger.new)
    {
    if(o.isWon == true && o.HasOpportunityLineItem == true && ( o.Type == 'A Membership' || o.Type == 'AB Membership' || o.Type == 'A Membership Upgrade' || o.Type == 'AB Membership Upgrade' ) )
    {
    String opptyId = o.Id;
    Asset[] ast = new Asset[]{};
    Asset a = new Asset();
    {
    a = new Asset();
    a.AccountId = o.AccountId;
    a.Product2Id = '01tA0000003N1pW';
    a.Quantity = o.Inclusive_Training_Spaces_Allocated__c;
    a.Price = 300;
    a.PurchaseDate = o.CloseDate;
    a.Status = 'Purchased';
    a.Description = 'Allocated Spaces';
    a.Name = 'Membership Inclusive Training';
    ast.add(a);
    }
    insert ast;
    }
    }
    }

    If anyone could help me out on this I would be grateful!

    Thanks

    hi jitendra in salesforce how we can track vehicle current position and based on that we can implement geo fencing can you please suggest me something

    1. JitendraZaa Avatar
      JitendraZaa

      Hi Dinesh,
      There is no Out of box functionality available. You need to write Client program may be in Java or .Net , which track vehicle position using GPS kit and using Web service update record inside salesforce.

        i want to write code in salesforce trigger.i am able to track vehicle current position in salesforce using google maps but i am not able to implement geo fencing issue.can you plz suggest me any thing

          Hi Dinesh,
          Can you please explain what exactly u mean by Geo Fencing ? U want to receive SMS or something when vehicle is outside boundry ?

          1. Dinesh Singla Avatar
            Dinesh Singla

            when vehicle go out side 5 km boundary of a predefined route.then i just have to set a variable true

          2. JitendraZaa Avatar
            JitendraZaa

            And how you are tracking vehicle location in google maps ? How you are getting co-ordinates ? There must be some GPS enabled API you are using

          3. Dinesh Singla Avatar
            Dinesh Singla

            we are using gprs device and VB.net code.and getting the location on sales force(using WSDL CLASS).then we are using google v3 maps to track its current position

          4. JitendraZaa Avatar
            JitendraZaa

            In that case, your VB.Net should check if Vehicle is going outside and if it is case then it should call Salesforce Web service. Salesforce Webservcie just have to update variable. MOst of work should be done by VB.Net code only.

    hi
    I have build a Ftp server using filezilla server .locally I am able to connect with it.

    but when I try to connect it with https://dataloader.io (after login ->new task->import->after choosing object ->FTP->new connection).

    When I give those credential it showing connection refused.

    In that login what host url we have to use so that we can connect to It.

    I am also using http://ftptest.net/#result to see my ftp connection

    how i make my ip address global so that i can connect plz reply

    1. JitendraZaa Avatar

      Where is your FTP Server ?
      On Local host or somewhere else ?
      If you are trying to connect FTP server present on your local system from DataLoader.io, thrn it is not possible. Your FTP server must be on some public accessible address.

      1. Dinesh Singla Avatar
        Dinesh Singla

        its on local server.
        how to make public accessible server can u plz give me some link or any document so that i will able to connect it to DataLoader.io thanks in advance.

          public means, Computer is on internet. Best way to do is Buy Web Hosting. They provides free FTP Server. You connect dataloader.io with those web servers.
          Making your computer to public is whole lot different path to networking.

        1. JitendraZaa Avatar
          JitendraZaa

          It is possible but only by API. You may need to create Java or .Net middle layer which will connect to Salesforce as well as FTP Server.
