[SalesForce] regarding External entry point

i have one custom field called Unique_Vendor_Id__c on account object (external id checkbox checked) and its auto-number.

now in test class when i create account for test data Unique_Vendor_Id__c should be automatically created as soon as account created, and in controller i am fetching data from that Unique_Vendor_Id__c if available.

now when i run test class it gives me following error :

System.StringException: Invalid id: null

and in stack trace :

External entry point Class.VendorAndChargeCreationControllerTest.VendorAndChargeCreationControllerTestMethod1: line 45, column 1

so from this error i think autonumber field is not generating id at a time of account creation am i right?

please let me know do i have to change any thing in field for generating that autonumber field in test data?

thank you in advance.

As you haven't supplied any code this is only a guess based on a typical problem...

When something happens in the database changed field values (with the exception of object Id fields when records are created) are not automatically brought back into the Apex code. So you have to requery the data to see the new values.

[SalesForce] unexpected exception: prcieBookBasedOnMarket: System.StringException: Invalid id: id: External entry point

Issue in your line opty.Pricebook2Id = priceBookNameMap.get('id');

priceBookNameMap.get('id'); map will return Name(string) not Id..

Modify your code and assign Id to opty.Pricebook2Id

Here Pricebook2Id dataType is Id. So you need to assign Id

Looks like relationship is opportunity owner, userid, createdby in pricebook

Create a map and store createdbyId to PriceBook2 record

map<Id, PriceBook2> mapUserIdToPriceBook2 = new map<Id, PriceBook2>();
for(PriceBook2 prc : pricebook) {
            mapUserIdToPriceBook2.put(prc.CreatedById, prc);
}

And below map based on ownerId get Pricebook2Id

for(Opportunity opty : newTrigger) {

    if(mapUserIdToPriceBook2.containkey(opty.OwnerId))
    {
        opty.Pricebook2Id = mapUserIdToPriceBook2.get(opty.OwnerId).Id;
    }
}

[SalesForce] Test class for a controller – Unable to set the variable in the constructor

Since you are not passing REFERER as parameter which you are trying to access in the constructor, that's why the error is.

So, before creating instance of the stdController, assign header value.

@isTest
public class xyzControllerTest{


 static testMethod void testMethod1(){

     object__c sr = new object__c (Name='test');
     insert sr;
     PageReference pageRef = Page.Thepage;
     Test.setCurrentPage(pageRef);
     ApexPages.currentPage().getParameters().put('id',sr.Id);
     ApexPages.currentPage().getParameters().put('pageMessage', 'Amessage');  
     ApexPages.currentPage().getHeaders().put('REFERER', sr.id + '/e');  
     ApexPages.StandardController stdcontroller = new ApexPages.StandardController(sr);

     xyzController controller = new xyzController(stdcontroller);     
 }

}

Controller

Also, put a null check before using referrer

public class XYZcontroller{
public object__c sr{get;set;}
public String srid {get;set;}
public XYZcontroller(ApexPages.StandardController controller) 
{
    sr = (object__c) controller.getRecord();
    srid = String.valueOf(controller.getId()).substring(0, 15);
    String pageMessage = ApexPages.currentPage().getParameters().get('pageMessage');
    boolean doNotDisplay;

    String referrer = ApexPages.currentPage().getHeaders().get('REFERER');
    if(referrer !=null && referrer.contains(srid+ '/e'))
    {
        doNotDisplay = false;
    }else
    {
        doNotDisplay=true;
    }
}
