Test class Help for a newbie

Hi Everyone!

I am still learning about apex and I've created a class but now I am lost as to where and how to create a test class.


public class myVFController{

    public myVFController(ApexPages.StandardController controller) {

    }

     public string testobject{get;set;} 
     public integer count{get;set;}
     public integer count1{get;set;}
     public integer count2{get;set;}
     public integer count3{get;set;}
     public integer count4{get;set;}
     public integer count5{get;set;} 
     public integer count6{get;set;}
     public integer count7{get;set;}
     public integer count8{get;set;}
     public integer count9{get;set;}
     public integer count10{get;set;}
     public integer count11{get;set;}
     public integer count12{get;set;}
     public integer count13{get;set;}
     public integer count14{get;set;}
     public integer count15{get;set;} 
    
public ApexPages.StandardSetController stdCntrlr {get; set;}
 public myVFController(ApexPages.StandardSetController controller) {
        stdCntrlr = controller;
    }
        
    public pagereference myvfcontroller1(){
       // count++;
     
        VF_Count__c mc = VF_Count__c.getInstance('Count1');        
        system.debug('mc'+mc);
           
        count1 = integer.valueof(mc.Count__c);
        count1++;
        
        VF_Tracking__c newTracking = new VF_Tracking__c(User__c=UserInfo.getUserId(),VF_Page_Visited__c='10-21-16 Alt Net Option',Datetime_Visited__c=datetime.now());
        insert newTracking; 
        VF_Count__c countinsert = new VF_Count__c();
        countinsert.name = 'Count1';
        countinsert.count__c = count1;
        countinsert.id =mc.id;
        update countinsert;
        testobject = newTracking.id;
        system.debug('newTrackingnewTracking'+newTracking);
        return null;
    }

Any help is greatly appreciated!

Please check below post to learn about test classes
1) http://amitsalesforce.blogspot.com/search/label/Test%20Class
2) http://amitsalesforce.blogspot.com/2015/06/best-practice-for-test-classes-sample.html

Please try below code
@isTest 
public class myVFControllerTest 
{
	static testMethod void testMethod1() 
	{
		Account testAcct = new Account (Name = 'My Test Account');
		insert testAcct;
		
		VF_Count__c vfCount = new VF_Count__c();
		vfCount.name ='Count1';
		vfCount.Count__c=1;
		insert vfCount;

		ApexPages.StandardController sc = new ApexPages.StandardController(testAcct);	
		myVFController obj = new myVFController(sc);	
		
		obj.myvfcontroller1();
	}
}


Please follow below salesforce Best Practice for Test Classes :-

1. Test class must start with @isTest annotation if class class version is more than 25
2. Test environment support @testVisible , @testSetUp as well
3. Unit test is to test particular piece of code working properly or not .
4. Unit test method takes no argument ,commit no data to database ,send no email ,flagged with 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 ,we should make sure that every use case should covered 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 ,no 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 .

Thank you for the quick response, I tried using what you provided into my class but I keep getting an error no matter what I do.

Constructor not defined: [myVFController].<Constructor>(ApexPages.StandardController)

  ApexPages.StandardController sc = new ApexPages.StandardController(testAcct); 
  myVFController obj = new myVFController(sc);  ---------Pointing to this line being the error.

I hope you did not delete the below code from your class
public class myVFController{

    public myVFController(ApexPages.StandardController controller) {

    }

If you want to you ApexPages.StandardSetController then update your test class like below
 
@isTest 
public class myVFControllerTest 
{
	static testMethod void testMethod1() 
	{
		List <Account> lstAccount = new List<Account>();

		Account testAcct = new Account (Name = 'My Test Account');
		lstAccount.add(testAcct);
		insert  lstAccount
		
		VF_Count__c vfCount = new VF_Count__c();
		vfCount.name ='Count1';
		vfCount.Count__c=1;
		insert vfCount;

        ApexPages.StandardSetController stdSetController = new ApexPages.StandardSetController(lstAccount);
        stdSetController.setSelected(lstAccount);
        myVFController obj= new myVFController(stdSetController);
        
        obj.myvfcontroller1();
	}
}

Let us know if this will help you

Thank you, no longer getting the error.  One last question , when I go into my class it's showing my code coverage as 0%.  Why hasn't that increased?
Amit Chaudhary 8Amit Chaudhary 8
I hope after saving the test class you also click on runTest button ?
