Wrapper Class test class - how to replicate marking a record as being selected in Test class

Hi, I'm struggling to find a way to replicate selecting a record in a visualforce page. Without somehow making the record in the test class selected nothing is being checked against the test code, Any help greatly appreciated! 
Extract from Test Class

// Set-up of Test Records here

// Set up visualforce parameters

PageReference pageRef = Page.CloneDeal;


// create an instance of the controller
Checkbox_class myPageCon = new Checkbox_class();





e in the test class. 
Extract from Visualforce page

<apex:page controller="Checkbox_Class" Tabstyle="Deal_Protocol__c">
 <apex:stylesheet value="/sCSS/21.0/sprites/1297816277000/Theme3/def​ault/gc/versioning.css" /> 
  <apex:sectionHeader title="Clone Deal: "/>

  <apex:form id="theform" >

      <apex:commandButton action="{!CloseFrm}" value="Cancel & Return" />
            <apex:pageBlockSection Title="Transaction to be Cloned - Check box to select item(s) to clone">
                <apex:dataTable value="{!deals}" var="a" columnswidth="50px,50px" cellpadding="4" border="1">

Oh, I misunderstood... You manipulate the members  or the getters of the Controller class directly. After it's all loaded up do stuff like. 

mypageCon.DealList.get(0).selected = true;//select the first item using the members

myPageCon.getDeals.get(0).selected = true;//select the first item using the getter

You will have to manually construct the test data in your test class. So you'll have to do stuff like 

Deal_c testDeal = new Deal__c();
testDeal.field = yadda;
insert testDeal;

Deal_Protocol__c testProtocol = new Deal_Protocol__c();
testProtocol.Deal_protocol_ref__c =;
etc, etc, etc

don't worry about it being inserted into your production. The testing protocol is smart enough to to carve out a "separate" space for test record and delete them after the test is done. It's great because you can set up all the appropriate scenarios but it's tedious in that you have to set them up by hand. 

You can also load test data from csvs you store as static resources using 
You can learn a bit more on this here

I favor doing it code and creating some factory classes to help create objects with common settings. That one you only have one spot to see what the parameters of the test are. 
Thanks - but that wasnt my question. The test records have all been created (just excluded from the code extract).  The visualforce page you see has a checkbox to select which records you want to clone. I need a way to replicate setting the 'selected' box to true in the test class as at the moment calling the 'getFees' method for example doesnt flag anything as selected=true and therefore nothing is tested as the size of the lists are zero.  How can I set the 'selected' flag to true in the test class??

Perfect. This got me to the right place. For completeness for others I needed to do a couple of other things. (1) add the @TestVisible before all of my list list variables ( I think you could also use Public instead). The test class couldn't read the lists without this, and (2) call the list first ( see attached code extract) before changing the selected status.

Thanks very much DevArrah for your prompt reply
myPagecon.FeeList = myPageCon.getFees();
myPagecon.FeeList.get(0).selectedf = true;
