Test class for a custom controller

Hi,  I have written a vf page and a custom controller to use the page on my home page as a  home page component. So I am not really passing any ID to the vf page. It just uses a table to display some values on the home page as the current user. How do I write a test class for this? Please advice me.

public with sharing class FinancialCashAudit {

    public List<Cash_Audit__c> cashAudit{get; set;}

    public List<Cash_Audit__c> cashAuditlist;

    public Integer counter = 0;

    public Integer list_size = 5;

    public Integer total_size;

    private List<Id> ophier;

    public FinancialCashAudit(){

        ophier = new List<Id>();

        for(User_Access__c use : [select id, Operational_Hierarchy__c from User_Access__c where User__c = :UserInfo.getUserId() and active__c = true]){

            ophier.add(use.Operational_Hierarchy__c);

        }

        cashAudit = [select name, Operational_Hierarchy__c, Operational_Hierarchy__r.Name,

                    Submitted_By__c, Submitted_By__r.Name, Submitted_Date__c from Cash_Audit__c

                    where Operational_Hierarchy__c IN :ophier ];

        total_size  = cashAudit.size();

        

    }

    public List<Cash_Audit__c> getcashAuditlist(){

        cashAuditlist = [select name, Operational_Hierarchy__c, Operational_Hierarchy__r.Name,

                    Submitted_By__c, Submitted_By__r.Name, Submitted_Date__c from Cash_Audit__c

                    where Operational_Hierarchy__c IN :ophier ORDER BY Submitted_Date__c DESC  LIMIT: list_size OFFSET : counter];

        return cashAuditlist;

    }

    public PageReference Beginning(){

        counter = 0;

        System.debug('Counter is '+counter);

        getcashAuditlist();

        return null;

    }

    public PageReference Previous(){

        counter -= list_size;

        System.debug('Counter is '+counter);

        getcashAuditlist();

        return null;

    }

    public PageReference Next(){

        counter += list_size;

        System.debug('Counter is '+counter);

        getcashAuditlist();

        return null;

    }

    public pageReference End(){

        counter = total_size - math.mod(total_size, list_size);

        System.debug('Counter is '+counter);

        getcashAuditlist();

        return null;

    }

     public Boolean getDisablePrevious(){

        if(counter==0) return true;

        else return false;

    }

    public Boolean getDisableNext(){

        if((counter + list_size) > total_size) return true;

        else return false;

    }

    public Integer getPageNumber(){

        if(math.mod(counter, list_size)>0){

            return counter/list_size + 1;

        }else{

            return counter/list_size ;

        }

    }

    public Integer getTotalPages(){

        

            return (total_size/list_size);

        

    }

   

    

}

This controller displays all the cash audits with operational hierarchy. the way it is shared is there is a object called User Access which has fields User and  operational_hierarchy. Please give me some idea on how to start on this.

Thank you

    You write a test class for this the same way that you would any other:

    - Set up some data for the controller to access (in this case it looks like User_Access__c and Cash_Audit__c records)

    - Instantiate the controller - as its custom you don't need to pass any parameters

    - Execute a method/methods

    - Verify the behaviour with asserts.

    The fact that the class is used as a controller is fairly immaterial.
