Writing test class - still 0% of coverage

[Nervosa]

Greetings to everyone!

I've got a problem writing test for my Apex controller. Here is controller:

public class Fullfunctionality_2 {
 
   private List<Item__c> items;
   private String sortDirection = 'ASC';
   private String sortExp = 'name';
   public String NewItemName {get; set;}
   public Integer NewItemQuantity { get; set; }
   public Integer NewItemPrice { get; set; }
   public String NewItemType { get; set; }
   public Date NewItemReleaseDate { get; set; }
   public String IdToDel { get; set; }
   public string searchText {get;set;}
   public List<Item__c> searchResults {get;set;}

   public List<SelectOption> getTypes(){
       List<SelectOption> types = new List<SelectOption>();
       Schema.DescribeFieldResult fieldResult = Item__c.Item_Type__c.getDescribe();
       List<Schema.PicklistEntry> ple = fieldResult.getPicklistValues();
       for( Schema.PicklistEntry f : ple)
           {
              types.add(new SelectOption(f.getLabel(), f.getValue()));
           }       
       return types;
    }
    
   public PageReference add(){

        Item__c NewItem = new Item__c(            
                Name = NewItemName,
                Item_Price__c = NewItemPrice,
                Items_Available__c = NewItemQuantity,
                Item_Type__c = NewItemType,
                Release_Date__c = NewItemReleaseDate);
                insert NewItem; 
                ViewData();
                PageReference curPage = ApexPages.currentPage(); 
                curPage.getParameters().put('success','true');
                curPage.getParameters().put('id',Apexpages.currentPage().getParameters().get('id'));
                curPage.setRedirect(true);
                NewItemName=null;
                NewItemQuantity=null;
                NewItemPrice = null;
                NewItemReleaseDate = null;
                return null; 
    }     
   public PageReference del() {

        Item__c ItemToDel = [SELECT id
                             FROM Item__c
                             WHERE id = :IdToDel];
        delete ItemToDel;   
               
        PageReference curPage = ApexPages.currentPage(); 
        curPage.getParameters().put('success','true');
        curPage.getParameters().put('id',Apexpages.currentPage().getParameters().get('id'));
        ViewData();
        curPage.setRedirect(false);       
        return curPage;
            
    }    

  public PageReference search() {
        String qry = 'select id, name, createddate, item_price__c from Item__c ' +
        'where name LIKE \'%'+searchText+'%\' order by name';
        searchResults = Database.query(qry);
        PageReference curPage = ApexPages.currentPage(); 
        curPage.getParameters().put('success','true');
        curPage.getParameters().put('id',Apexpages.currentPage().getParameters().get('id'));
        ViewData();
        curPage.setRedirect(true);       
        return null;        
  }    

   public String sortExpression
   {
     get
     {
        return sortExp;
     }
     set
     {
       if (value == sortExp)
         sortDirection = (sortDirection == 'ASC')? 'DESC' : 'ASC';
       else
         sortDirection = 'ASC';
       sortExp = value;
     }
   }

 public String getSortDirection()
 {
    if (sortExpression == null || sortExpression == '')
      return 'ASC';
    else
     return sortDirection;
 }

 public void setSortDirection(String value)
 {  
   sortDirection = value;
 }
  
   public List<Item__c> getItems() {
       return items;
   }

   public PageReference ViewData() {
   
       string sortFullExp = sortExpression  + ' ' + sortDirection;
       items = Database.query('Select id, Name, Item_Price__c, CreatedDate from Item__c order by ' + sortFullExp + ' limit 1000');
       return null;
   }
}

 I wrote a piece of test, it looks like this:

@isTest
private class TestFullFunctionality_2 {

static testMethod void testItemEnter() {

    Item__c NewItem = new Item__c(name = 'NEWITEM', Item_Price__c = 100, Item_Type__c = 'Solid', Items_Available__c = 10 );
    insert NewItem;
    Test.startTest();
    Test.stopTest();    
}
}

 ...but still the code coverage total is 0%. What do i do wrong?

Thanks in advance.

Hi,

For this you have to 

1) Insert a record of Item

2)Created a controller of your class

3)Pass the record to your controller

4)call the methods of your class

Please let me know if you are facing any issue.

Thanks

1) Insert a record of Item

Aren't I doing this by my testItemEnter() method?

2)Created a controller of your class

What is it - CONTROLLER OF CLASS ???

3)Pass the record to your controller

Isn't it passed by insert NewItem command?

Hi,

Do something like this:

// this need to be done at the start
static TestFullFunctionality_2 ext;

// You insert item
Item__c NewItem = new Item__c(name = 'NEWITEM', Item_Price__c = 100, Item_Type__c = 'Solid', Items_Available__c = 10 );
insert NewItem;

ApexPages.StandardController con1 = new ApexPages.StandardController(NewItem );
ext = new TestFullFunctionality_2(con1);
You need to call all the methods like this:

ext.add();
ext.delete();

Please mark it resolved if this is the answer of youe question.

Thanks:))

Okay. I've done it like this -

@isTest
private class TestFullFunctionality_2 {
    
static testMethod void testAdd() {
    TestFullFunctionality_2 ext;
    Item__c NewItem = new Item__c(name = 'NEWITEM', Item_Price__c = 100, Item_Type__c = 'Solid', Items_Available__c = 10 );
    insert NewItem;
    ApexPages.StandardController con1 = new ApexPages.StandardController(NewItem);
    ext = new TestFullFunctionality_2(con1);

    Test.startTest();
    Test.stopTest();    
}
}

 but it can't even be saved, i see an error "Error: Compile Error: Constructor not defined: [TestFullFunctionality_2].<Constructor>(ApexPages.StandardController) at line 9 column 11"

Spoiler

Sorry for being too annoying...

Hi ,

try this

i got the problem

@isTest
private class TestFullFunctionality_2 {

static testMethod void testAdd() {
TestFullFunctionality_2 ext;
Item__c NewItem = new Item__c(name = 'NEWITEM', Item_Price__c = 100, Item_Type__c = 'Solid', Items_Available__c = 10 );
insert NewItem;

TestFullFunctionality_2 Con=new TestFullFunctionality_2();
Con.add();
Con.del();
Con.search();
Con.viewData();

//you can call all your methods and provide parameter to the methods if needed.

}
}

it should work :))

Thanks:))

Hey, it almost helped me! I changed test class like this:

@isTest
private class TestFullFunctionality_2 {

String NewItemName = 'NEWITEM';
Integer NewItemPrice = 100;
String NewItemType = 'Solid';
Integer NewItemQuantity = 10;

static testMethod void testAdd() {
TestFullFunctionality_2 ext;

FullFunctionality_2 Con=new FullFunctionality_2();
Con.add();
Con.del();
Con.search();
Con.viewData();

}
}

 Now total coverage is 32% !!! But i get an error:

System.DmlException: Insert failed. First exception on row 0; first error: REQUIRED_FIELD_MISSING, Required fields are missing: [Item_Price__c]: [Item_Price__c]

 I think i'm very close to solution =)

Hi,

I think you have to insert a item record which you removed from code and please make sure that need to insert all the mandatory field of that object otherwise it will throw error.

Item__c NewItem = new Item__c(name = 'NEWITEM', Item_Price__c = 100, Item_Type__c = 'Solid', Items_Available__c = 10 );
insert NewItem;

Please put this line in your code.

Thanks:))

Okay. Now test class looks like this:

@isTest
private class TestFullFunctionality_2 {

String NewItemName = 'NEWITEM';
Integer NewItemPrice = 100;
String NewItemType = 'Solid';
Integer NewItemQuantity = 10;

static testMethod void testAdd() {
TestFullFunctionality_2 ext;
Item__c NewItem = new Item__c(name = 'NEWITEM', Item_Price__c = 100, Item_Type__c = 'Solid', Items_Available__c = 10 );
insert NewItem;
FullFunctionality_2 Con=new FullFunctionality_2();
Con.add();
Con.del();
Con.search();
Con.viewData();

}
}

 and still i get the same error:

System.DmlException: Insert failed. First exception on row 0; first error: REQUIRED_FIELD_MISSING, Required fields are missing: [Item_Price__c]: [Item_Price__c]
