Dear  all, forgive the level of newbiness. I'm trying to use the simplest code structures at first to get myself use to Apex coding.

So I am trying to make a Visual Force page that lets me make an Account and Contact in one (or two) page(s).

Essentially I was/am following the Visualforce Developer's Guide but rather than create Account, Contact, Opportunity and Opportunity Contact Role, I only want to create an Account and Contact. I thought that might be simpler :/

I found a class (controller) that supposedly does this, rather than chop the VF Dev' Guide example down..especially as the VF Dev' Guide didn't have a test class for their example. :(

public class newAccContactController {

public Account account { get; set; }
public Contact contact { get; set; }

public newAccContactController() {
account = new Account();
contact = new Contact();
}

public PageReference next() {
return Page.newAccContactStep2;
}

public PageReference previous() {
return Page.newAccContactStep1;
}

public PageReference save() {
Database.insert(account);
contact.accountId = account.id;
ApexPages.StandardController contactController = new ApexPages.StandardController(contact);
return contactController.save();
}
}

  but  I'm unable to find/figure out quite how to test a controller.

I found a controller test class for a slightly difference controller but I'm still stuck trying to mangle it to meet my needs. If I run this test below I get 50% coverage, but I'm not even sure it's testing what needs to be tested :/

@isTest
private class testAccContactController {

static testMethod void myNewAccContactController() {
// TO DO: implement controller test
//Use the PageReference Apex class to instantiate a page
PageReference pageRef = Page.newAccContactStep1;

//In this case, the Visualforce page named 'newAccContactStep1'
//is the starting point of this test method.
Test.setCurrentPage(pageRef);
//Instantiate and construct the controller class.
newAccContactController controller = new newAccContactController();

//Example of calling an Action method. Same as calling any other Apex method.
//Normally this is executed by a user clicking a button or a link from the Visualforce
//page, but in the test method, just test the action method the same as any
//other method by calling it directly.

//The .getURL will return the page url the Save() method returns.
String nextPage = controller.save().getUrl();

//Check that the save() method returns the proper URL.
System.assertEquals('/apex/failure?error=noParam', nextPage);

//Add parameters to page URL
ApexPages.currentPage().getParameters().put('qp', 'yyyy');

//Instantiate a new controller with all parameters in the page
controller = new newAccContactController();

//Example of calling the 'setter' method for several properties.
//Normally these setter methods are initiated by a user interacting with the Visualforce page,
//but in a test method, just call the setter method directly.
//controller.setLastName('lastname');
//controller.setFirstName('firstname');
//controller.setCompany('acme');
//controller.setEmail('firstlast@acme.com');
nextPage = controller.save().getUrl();

//Verify that the success page displays
System.assertEquals('/apex/success', nextPage);
}
}

and the results of running this test:

*** Beginning Test 1: testAccContact.static testMethod void myNewAccContactController()

 I'm sure for some this is bleedingly obvious/simple, and I hope that once I get past this stage the light will go on for the subsequent tests that I'll surely be writing.

Thank you anyone that can help me here.
