Unit Test for controller - redirect from select list

i have a method in a custom controller that redirects a user to a page based on a value they have selected from a dropdown list (selectList). this list is populated via a property in the controller. how do a unit test this redirect? specifically, how do i load the values into the dropdown list so that the redirect can be simulated (right now i'm getting a null exception because the dropdown list is never loaded)?

Could you please share your code, will be helpful in giving you any advice in writing test method.

my controller:

 

public class myController {

    public String states;
   
    public PageReference RedirectToState() {
        if(states != null){
            PageReference pageRef = new PageReference('/' + states);
            pageRef.setRedirect(true);
            return pageRef;
        }
        else {
            return null;
        }
    }

    public List<SelectOption> getItems() {
        List<SelectOption> options = new List<SelectOption>();
        options.add(new SelectOption('','--Select a State--'));
        options.add(new SelectOption('TX','Texas'));
        return options;
    }
       
    public String getStates() {
        return states;
    }
       
    public void setStates(String states) {
        this.states = states;
    }
}

 

excerpt from my component/Page:

 

<div id="statesSelect">
        <img src="{!URLFOR($Resource.myRsc, 'images/it-states-dropdown-lbl.gif')}" id="lbl" />
        <apex:form >
            <apex:selectList styleClass="certStates" size="1" value="{!states}" multiselect="false">
                <apex:actionSupport action="{!RedirectToState}" event="onchange" />
                <apex:selectOptions value="{!items}"></apex:selectOptions>
            </apex:selectList>
            <apex:messages />
        </apex:form>      
    </div>



my unit test that isn't working (ref is null):

 

public static testMethod void testStatesRedirect(){
       PageReference refStart = new PageReference('/Home');
       
       Test.setCurrentPage(refStart);
       
       myController controller = new myController();
       
       controller.getStates();
       
       PageReference ref = controller.RedirectToState();
       
       System.assertEquals('correctPage', ref.getUrl());
   }
