I am new to Salesforce . I need to write a test class for custom controller. 
Please help me

I'm new to apex coding and have run into a bit of a problem which I'm hoping someone can help with. 

Basically, I've been tasked with a Salesforce deployment for my company a part of which requires a customer portal for viewing cases. Following some early prototyping we decided to use a piece of apex programming to display the case list in a format that is suited to our needs. The list basically consists of a drop down box that has two options, depending on the option chosen the class will pull data from Salesforce. this is being used on a visualforce page that is embedded into the community site.

I've used this code in Sandox with no issues but when I try to deploy to Production it fails due to only 71% code coverage. 
 

public class CommunityCaseList {

public string options;
       
    public List<Case> getNewCases() {
    
        if(options=='Open')
        {
        
        List<Case> results = [SELECT id,CaseNumber,Status,Priority,Accountid,Account.Name,Contactid,contact.name,subject,CreatedDate,ClosedDate FROM Case WHERE Status != 'Closed' ORDER BY CreatedDate DESC];
            return results;
        }
    
        else if(options == 'Closed'){
            
            List<Case> results = [SELECT id,CaseNumber,Status,Priority,Accountid,Account.Name,Contactid,contact.name,subject,CreatedDate,ClosedDate FROM Case WHERE Status = 'Closed' ORDER BY CreatedDate DESC];
            return results;            
        }
        
        else {
            
            List<Case> results = [SELECT id,CaseNumber,Status,Priority,Accountid,Account.Name,Contactid,contact.name,subject,CreatedDate,ClosedDate FROM Case WHERE Status != 'Closed' ORDER BY CreatedDate DESC];
            return results;
            
        }
    
    
    
    }
    
    public string getOptions() {
        return this.options;
    }
    public void setOptions(String Opt) {
        this.options=opt;
        
    }
    public list<SelectOption> getItems() {
      List<selectOption> options = new List<SelectOption>();
        options.add(new Selectoption('Open','Open'));
        options.add(new Selectoption('Closed','Closed'));
        return options;
        
    }
    public pagereference preview() {
        return null;
    }    

}

I've read up on it and believe I need to create a test class to run the code but when I'm trying to create one it displays the code as incorrect. This is the test class:
 

@isTest

private class CommunityCaseListTest {
 
    static testMethod void validateCommunityCaseList() {


public string options;
       
    public List<Case> getNewCases() {
    
        if(options=='Open')
        {
        
        List<Case> results = [SELECT id,CaseNumber,Status,Priority,Accountid,Account.Name,Contactid,contact.name,subject,CreatedDate,ClosedDate FROM Case WHERE Status != 'Closed' ORDER BY CreatedDate DESC];
            return results;
        }
    
        else if(options == 'Closed'){
            
            List<Case> results = [SELECT id,CaseNumber,Status,Priority,Accountid,Account.Name,Contactid,contact.name,subject,CreatedDate,ClosedDate FROM Case WHERE Status = 'Closed' ORDER BY CreatedDate DESC];
            return results;            
        }
        
        else {
            
            List<Case> results = [SELECT id,CaseNumber,Status,Priority,Accountid,Account.Name,Contactid,contact.name,subject,CreatedDate,ClosedDate FROM Case WHERE Status != 'Closed' ORDER BY CreatedDate DESC];
            return results;
            
        }
    
    
    
    }
    
    public string getOptions() {
        return this.options;
    }
    public void setOptions(String Opt) {
        this.options=opt;
        
    }
    public list<SelectOption> getItems() {
      List<selectOption> options = new List<SelectOption>();
        options.add(new Selectoption('Open','Open'));
        options.add(new Selectoption('Closed','Closed'));
        return options;
        
    }
    public pagereference preview() {
        return null;
    }    

}

}

I'm not quite sure what I'm doing wrong or if there's an easier way to achieve the code coverage required. The tutorials I've read so far are for creating test classes that manipulate data whereas this is simply used to get data.

If anyone can help point me int he right direction it would be greatly appreciated. 

Many thanks

Andy

 i had created a custom object of emplye data  with feilds  like   name , experience, address, salary ,and created a record and got the recordid ='allxxwe22522' .. i need to create a class with all the details of that id and display it    :

Hi,

I a string and it has 'AND' sting multiple times how to find a number of times sub-string occurs in a string.
He is my code
String str=  AccountName AND AccountPhone;
integer ct=?

Hi,
I have 3 objects:
Opportunity
Pro__c
Unc__c 
(Pro__c and Unc__c has lookup to opportunities)

To get unc__c values from Opportunities i am using this query,
select name from opportunity where unc__r.id='idvalue'


can I query from Unc__c to get opportunities??
If so, How?

AND (OR(NOT($Profile.Name = 'Integration User'),NOT( $User.Username ='xyz')) , Owner:Queue.DeveloperName ='abc')
is the validation rule condition .Its working when only profile check is added but not when both profile and user check is done in the condition.Will logged in user based check work in validation rules??

I have two object 
1. Account
2. BCC (related object to acount)
Account has external id field "BCC customer code" and BCC object has field "BCC code" and "status".
Requirement : When BCC code status is active then only that BCC code should show in "BCC customer code" on Account detail page.
how to write trigger for this.

New to coding and would really appreciate any help that can be provided.

I am trying to write a test class for a function I have written that creates Opportunities for each account in a list.  On compile I am receiving the error 'Method does not exist or incorrect signture: void CreateOpptys(Id, List) from the type multiPicklistCtrl.  Can someone please tell me what I am doing wrong?

This is my test class:

static testmethod void CreateOpptysTest(){

        Account pAcct = new Account(Name = 'Test Property account', RecordTypeId=RecordTypeIdPropAccount);
        insert pAcct;
        
        PropertySpace__c pSpace = new PropertySpace__c(Name='Test Property Space', Property__c = pAcct.Id, SquareFootage__c = 2000);
        insert pSpace;

        List<Account> accts = new List<Account>();
        for (Integer i=0; i<20; i++) {
            accts.add(new Account(Name = 'Test Account -' +i, RecordTypeId=RecordTypeIdPropAccount));

Hello all,

I'm trying to populate owner's name to Enrollment_Rep__c field on Lead Object based on the profile name.  Everything works till I change the Owner from User to Queue.  I'm running to System.NullPointerException on the trigger.

trigger EnrollmentRep on Lead (before insert, before update) {
    
    Set<Id> ownerIds = new Set<Id>();

    for (Lead newLead : Trigger.new) {
        ownerIds.add(newLead.OwnerId); 
    }

    Map<Id,User> mapUsers = new Map<Id, User>([SELECT Id, Profile.Name, Name FROM User Where Id In :ownerIds]);

    for (Lead newLead : Trigger.new) {
        User oOwner = mapUsers.get(newLead.OwnerId);
        
        if (oOwner.Profile.Name == 'CEO'){
            newLead.Enrollment_Rep__c = oOwner.Name;
        }
    }
}

I'm new to the trigger and I'm not sure where to use IF statement Lead Owner != Queue.

Any suggestions will be helpful.

Thanks!

Can I have the scenario where I can have two records with the same Salesforce Ids with different cases. 
e.g. 
a124T000000kDCa   -- Ajay
a124t000000KDca   -- Hari 

The above is an example of 15 digit Id. Is this scenario possible ?
Is the same scenario possible with 18 digit Ids as well.

Please help.

I'm new to apex coding and have run into a bit of a problem which I'm hoping someone can help with. 

Basically, I've been tasked with a Salesforce deployment for my company a part of which requires a customer portal for viewing cases. Following some early prototyping we decided to use a piece of apex programming to display the case list in a format that is suited to our needs. The list basically consists of a drop down box that has two options, depending on the option chosen the class will pull data from Salesforce. this is being used on a visualforce page that is embedded into the community site.

I've used this code in Sandox with no issues but when I try to deploy to Production it fails due to only 71% code coverage. 
 

public class CommunityCaseList {

public string options;
       
    public List<Case> getNewCases() {
    
        if(options=='Open')
        {
        
        List<Case> results = [SELECT id,CaseNumber,Status,Priority,Accountid,Account.Name,Contactid,contact.name,subject,CreatedDate,ClosedDate FROM Case WHERE Status != 'Closed' ORDER BY CreatedDate DESC];
            return results;
        }
    
        else if(options == 'Closed'){
            
            List<Case> results = [SELECT id,CaseNumber,Status,Priority,Accountid,Account.Name,Contactid,contact.name,subject,CreatedDate,ClosedDate FROM Case WHERE Status = 'Closed' ORDER BY CreatedDate DESC];
            return results;            
        }
        
        else {
            
            List<Case> results = [SELECT id,CaseNumber,Status,Priority,Accountid,Account.Name,Contactid,contact.name,subject,CreatedDate,ClosedDate FROM Case WHERE Status != 'Closed' ORDER BY CreatedDate DESC];
            return results;
            
        }
    
    
    
    }
    
    public string getOptions() {
        return this.options;
    }
    public void setOptions(String Opt) {
        this.options=opt;
        
    }
    public list<SelectOption> getItems() {
      List<selectOption> options = new List<SelectOption>();
        options.add(new Selectoption('Open','Open'));
        options.add(new Selectoption('Closed','Closed'));
        return options;
        
    }
    public pagereference preview() {
        return null;
    }    

}

I've read up on it and believe I need to create a test class to run the code but when I'm trying to create one it displays the code as incorrect. This is the test class:
 

@isTest

private class CommunityCaseListTest {
 
    static testMethod void validateCommunityCaseList() {


public string options;
       
    public List<Case> getNewCases() {
    
        if(options=='Open')
        {
        
        List<Case> results = [SELECT id,CaseNumber,Status,Priority,Accountid,Account.Name,Contactid,contact.name,subject,CreatedDate,ClosedDate FROM Case WHERE Status != 'Closed' ORDER BY CreatedDate DESC];
            return results;
        }
    
        else if(options == 'Closed'){
            
            List<Case> results = [SELECT id,CaseNumber,Status,Priority,Accountid,Account.Name,Contactid,contact.name,subject,CreatedDate,ClosedDate FROM Case WHERE Status = 'Closed' ORDER BY CreatedDate DESC];
            return results;            
        }
        
        else {
            
            List<Case> results = [SELECT id,CaseNumber,Status,Priority,Accountid,Account.Name,Contactid,contact.name,subject,CreatedDate,ClosedDate FROM Case WHERE Status != 'Closed' ORDER BY CreatedDate DESC];
            return results;
            
        }
    
    
    
    }
    
    public string getOptions() {
        return this.options;
    }
    public void setOptions(String Opt) {
        this.options=opt;
        
    }
    public list<SelectOption> getItems() {
      List<selectOption> options = new List<SelectOption>();
        options.add(new Selectoption('Open','Open'));
        options.add(new Selectoption('Closed','Closed'));
        return options;
        
    }
    public pagereference preview() {
        return null;
    }    

}

}

I'm not quite sure what I'm doing wrong or if there's an easier way to achieve the code coverage required. The tutorials I've read so far are for creating test classes that manipulate data whereas this is simply used to get data.

If anyone can help point me int he right direction it would be greatly appreciated. 

Many thanks

I am trying to run this code in Anonymous window:

List<Contact> ConList = New List<Contact>();
ConList = [Select id, name, Account.name, Parent_Account__r.name from Contact where Parent_Account__r.name != Account.Parent.name];
System.debug('Contact records :    ' + Con1);

getting error:

Line: 2, Column: 9
Unexpected token '='.

I need to run below query in Dev console or workbench to get the contact records where Parent Account on Contact is not equal to Parent Account of Account:

select id, name, Account.name, Parent_Account__r.name,(Select id,name, Parent.name from Account) from Contact where Parent_Account__r.name != Account.Parent.name

Please help

    public pagereference login()
        {
        if(u.size()>0){
                 pagereference pgref = new pagereference('/apex/loginsf1');
            pgref.setredirect(true);
                 return pgref ;
        }
