Test class for the standard controller extention

Hi all,

how can we write test class for the standard controller extension. Below is my extenstion class
public class gdaControllerExtension {

    Public final GFrm__c gfrm;

    public gdaControllerExtension (ApexPages.StandardController stdController) {
        this.gfrm = (GFrm__c)stdController.getRecord();
    }

    
  public void mfarten()
  {

 
  if(gfrm.SelectProgram__c=='MA')
  {
      gfrm.Select_One_Art_Ed__c= null;
        
  }else if(gform.SelectProgram__c=='AED'){
 
      gfrm.SelectOne_MFA__c= null;

   
  }else if(gfrm.SelectProgram__c=='enroll'){
 
      gform.SelectOne_MFA__c= null;

 
  }
 
  }

}


Thanks in advance,

Regards,
mac.

Hi Mac,
  • May I Request you to Please check the sample test class code below.
@isTest 
public class ExtensionTestClass 
{
 static testMethod void testMethod1() 
 {
 Account testAccount = new Account();
 testAccount.Name='Test Account' ;
 insert testAccount;

 Test.StartTest(); 
  ApexPages.StandardController sc = new ApexPages.StandardController(testAccount);
  myControllerExtension testAccPlan = new myControllerExtension(sc);

  PageReference pageRef = Page.AccountPlan; // Add your VF page Name here
  pageRef.getParameters().put('id', String.valueOf(testAccount.Id));
  Test.setCurrentPage(pageRef);

  //testAccPlan.save(); call all your function here
 Test.StopTest();
 }
}
  • Please follow below salesforce Best Practice for Test Classes:-
1. Test class must start with @isTest annotation if class version is more than 25
2. Test environment support @testVisible , @testSetUp as well
3. A unit test is to test the particular piece of code working properly or not.
4. Unit test method takes no argument, commit no data to a database,s end no email, Flagged with the testMethod keyword.
5. To deploy to production at least 75% code coverage is required
6. System.debug statement are not counted as a part of apex code limit.
7. Test method and test classes are not counted as a part of code limit
9. We should not focus on the percentage of code coverage,w e should make sure that every use case should cover including positive, negative, bulk and single record .
Single Action -To verify that the the single record produces the correct an expected result .
Bulk action -Any apex record trigger, class or extension must be invoked for 1-200 records .
Positive behavior : Test every expected behavior occurs through every expected permutation , i,e user filled out every correctly data and not go past the limit .
Negative Testcase : -Not to add future date , Not to specify negative amount.
Restricted User: - Test whether a user with restricted access used in your code .10. Test class should be annotated with @isTest .
11 . @isTest annotation with test method  is equivalent to testMethod keyword .
12. Test method should static and no void return type .
13. Test class and method default access is private,n o matter to add access specifier .
14. classes with @isTest annotation can't be a interface or enum .
15. Test method code can't be invoked by non test request .
16. Stating with salesforce API 28.0 test method can not reside inside non test classes .
17. @Testvisible annotation to make visible private methods inside test classes.
18. Test method can not be used to test web-service call out . Please use call out mock .
19. You can't  send email from test method.
20.User, profile, organization, AsyncApexjob, Corntrigger, RecordType, ApexClass, ApexComponent ,ApexPage we can access without (seeAllData=true) .
21. SeeAllData=true will not work for API 23 version eailer .
22. Accessing static resource test records in test class e,g List<Account> accList=Test.loadData(Account,SobjectType,'ResourceName').
23. Create TestFactory class with @isTest annotation to exclude from organization code size limit .
24. @testSetup to create test records once in a method  and use in every test method in the test class .
25. We can run unit test by using Salesforce Standard UI,Force.com IDE, Console, API.
26. Maximum number of test classes run per 24 hour of period is  not grater of 500 or 10 multiplication of test classes of your organization.
27. As apex runs in system mode so the permission and record sharing are not taken into account . So we need to use system.runAs to enforce record sharing .
28. System.runAs will not enforce user permission or field level permission .
29. Every test to runAs count against the total number of DML issued in the process .

I hope it will be helpful.

Hi Rahul,
Thanks for the reply.
I hae written as below but hte methods are failed.
@istest
public class gdaControllerExtension_test {  
static testMethod void testreparentMethod()     {    
 GFrm__c gform = [SELECT ID FROM GFrm__c LIMIT 1];     ApexPages.StandardController stdController = new ApexPages.StandardController(gfrm);     gdaControllerExtension gdcon=new gdaControllerExtension(stdController);     
    gdcon.gfrm.SelectProgram__c='MA';
 gdcon.mfarten();   
}   
static testMethod void testparentreAddresMethod()     {     
GFrm__c gform = [SELECT ID FROM GFrm__c LIMIT 1];     ApexPages.StandardController stdController = new ApexPages.StandardController(gfrm);     gdaControllerExtension gdcon=new gdaControllerExtension(stdController);           
    gdcon.gfrm.SelectProgram__c='AED';
  gdcon.mfarten();   
}       
static testMethod void testparentresetAddressMethod()     {     
GFrm__c gform = [SELECT ID FROM GFrm__c LIMIT 1];     ApexPages.StandardController stdController = new ApexPages.StandardController(gfrm);     gdaControllerExtension gdcon=new gdaControllerExtension(stdController);     
     gdcon.gform.SelectProgram__c='Re-enroll';
 gdcon.mfarten();
  }
}

the methods are failed while running the testRun.

can you help me over here.

Thanks in advance.
