So I'm writing my first test class and I'm stuck. For my custom controller I adapted a sample wrapper class to my needs. Right now I'm getting 77% coverage but I need to define the selected boolean in my outside class to be true and I can't figure out how to do it. No matter what I try i keep getting an error that cMovie doesnt exist. How do I define cMovie in my test class so I can create an instance and set its boolean to true?

I've included my code below:

Apex Class:

public class RentalControllerWrapper {
    public List<cMovie> movieList {get;set;}
    public string movieIndex {get;set;}
    //contained class   
    public class cMovie {
         public Movie__c mov {get; set;}
         public Boolean selected {get; set;}
     
         //This is the contructor method. When we create a new cMovie object we pass a Movie that is set to the m property. We also set the selected value to false
         public cMovie(Movie__c m) {
             mov = m;
             selected = false;
         }
    }
     
     //This method uses a simple SOQL query to return a List of Movies
     public List<cMovie> getcMovie() {
         if(movieList == null) {
             movieList = new List<cMovie>();
             for(Movie__c m : [select Id, Name, price__c, description__c, total_inventory__c from Movie__c]) {
                 // As each contact is processed we create a new cMovie object and add it to the movieList
                 movieList.add(new cMovie(m));                 
             }
             //system.debug(movieList[0].mov.id);
         }
         return movieList;
     }
     
     public PageReference RentAllChecked() {
     //We create a new list of Movies if they are selected
     List<Movie__c> selectedMovies = new List<Movie__c>();
     //We will cycle through our list of cContacts and will check to see if the selected property is set to true, if it is we add the Movie to the selectedMovies list
     for(cMovie cMov : getcMovie()) {
         if(cMov.selected == true) {
             selectedMovies.add(cMov.mov);
         }
      }   
      // create new rental record
      Rentals__c newRentalRecord = new Rentals__c();
      insert newRentalRecord;
      
      for(Movie__c mv : selectedMovies) {
         //system.debug(mv);
         mv.total_inventory__c=mv.total_inventory__c-1;
         update mv;         
         // Create new Unit Rental Record and Insert
         Unit_Rental__c newUnitRentalRecord = new Unit_Rental__c();
         newUnitRentalRecord.Movie__c =  mv.ID;
         newUnitRentalRecord.Rental__c = newRentalRecord.ID;   
         insert newUnitRentalRecord;   
      }
      // Redirect to Success page passing rental record ID
      PageReference p = Page.RentalSuccess;
      p.getParameters().put('id', newRentalRecord.ID);
      p.setRedirect(true);
      return p; 
     }
     
     public PageReference Rent() { 
         for(cMovie cMov : getcMovie()) {
            if (cMov.mov.id==movieIndex){
                cMov.selected=true;                
            }
        }
      
        return null;           
     }

Test Class:

@isTest
private class RentalControllerWrapperTest {

    public static testMethod void RentalControllerWrapper() {
        Movie__c testmov=new Movie__c(Name='Movie1',Release_Date__c=System.now(),Description__c='Description',Price__c=1,Total_Inventory__c=10);
        insert testmov;     
               
        string movieIndex=testmov.ID; 
              
        Test.StartTest();
        RentalControllerWrapper controller=new RentalControllerWrapper();
        
        //controller.List<cMovie> testCMov=new List<cMovie>();
       
        controller.RentAllChecked();
        controller.Rent();                
        
        Test.stopTest(); 
    }
    
}
