I'm fresh out of the DEV501 class, and trying to create my first controller extension and accompanying test class.  I've got the extension done (it's really basic), but I struggled off and on all day yesterday with a test class for the extension.  I've looked at as many examples as I can find, but I can't figure otu how to call the  extension's 1 method from the test class.  It's all very easy stuff I know, I'm hoping someone in the community can spot my error easily.  It shouldn't be tough!  Here's what I've got:

public class ProjectBOMPrintoutExtension { public DriveCamProject__c project {get; set;} //This extension does a very simple thing. From a starting DriveCamProject__c, it polls the DB //for any associated project BOM line items that have quantity. These are the line items that //users are interested in when creating a site SO. There's a VF page that uses this list to //build a BOM printout. public List<Project_Product__c> siteBOM { get{ siteBOM = [Select Unit_Price__c, Site_Qty__c, Site_Extended_Amount__c, Part__c, Description__c From Project_Product__c where Project_Name__c=: apexpages.currentPage().getParameters().get('id') and Site_Qty__c > 0 Order by Part__c desc]; return siteBOM; } set;//not sure if we need a setter, but putting it in for now } public ProjectBOMPrintoutExtension (ApexPages.StandardController stdController){ this.project = (DriveCamProject__c)stdController.getRecord(); } //Test Method public static testMethod void testSiteBOMController() { // Create new Project and BOM line item Account TestAccount = [select id from Account limit 1]; String TestAccountId = TestAccount.Id; RecordType TestRecordType = [select id from RecordType where SobjectType='DriveCamProject__c' limit 1]; String TestRecordTypeId = TestRecordType.id; DriveCamProject__c p = new DriveCamProject__c(Name='Test Project',Account__c= TestAccountId, Status__c='Account Notification', RecordTypeId=TestRecordTypeId); insert p; Project_Product__c pp = new Project_Product__c(Name='Test PP', Project_Name__c = p.id); insert pp; // Get a page reference to our newly created project PageReference pg1 = new PageReference('/apex/ProjectBOMprintout?id='+p.Id); System.test.setCurrentpage(pg1); // TODO: Instantiate the controller (call it "controller") //ApexPages.standardController controller = new ApexPages.standardController(new DriveCamProject__c()); ApexPages.standardController controller = new ApexPages.standardController(p); // TODO: Instantiate the extension (call it "extension") ProjectBOMPrintoutExtension extension = new ProjectBOMPrintoutExtension(controller); // TODO: Instantiate the project from the extension DriveCamProject__c project = extension.project; //p = extension.project; ///!!!!!!!!!!Here's where it goes bad. I just need to call the controller method, but

////!!!!!!!!!I get errors about the method not existing or incorrect sig. // Execute the controller method List<Project_Product__c> BOMList = project.siteBOM(); // Check list isn't null System.assert(BOMList!=null); // Check list is expected size System.assertEquals(1, BOMList.size()); // Check contents of list are as expected System.assertEquals(BOMList[0].id, pp.id);

} }
