Yo Team,

I'm new to the apex development and really confuse how to use contructor in the Class. So I look other Sr.developer's code and mimic the apex class, I'm so lucky that works. But turn to Test, I kind stuck there. Following is my Apex class and test class(not working) I created, I truely appriate that if anyone could give me some advises.

Apex Class:

public class HouseholdpageController {
    List<Account> accounts;
    public Lead currentlead{get;set;}
    public ApexPages.StandardSetController stdCntrlr {get; set;}
    public HouseholdpageController (ApexPages.StandardController controller)
  {     
    this.currentlead = (Lead)controller.getRecord(); 
    }
    public List<Account> getAccounts(){
        currentlead = [ Select Id, Equifax_Household_ID__c from Lead where Id =: ApexPages.currentPage().getParameters().get('Id') ];
        if(currentlead.Equifax_Household_ID__c != null) accounts = [select name, Loan_Balance__c, Deposit_Balance__c from account where Equifax_Household_ID__c =: currentlead.Equifax_Household_ID__c];
     
        return accounts;
    }

}


Test Class(Error:System.QueryException: List has no rows for assignment to SObject)
/**
 * This class contains unit tests for validating the behavior of Apex classes
 * and triggers.
 *
 * Unit tests are class methods that verify whether a particular piece
 * of code is working properly. Unit test methods take no arguments,
 * commit no data to the database, and are flagged with the testMethod
 * keyword in the method definition.
 *
 * All test methods in an organization are executed whenever Apex code is deployed
 * to a production organization to confirm correctness, ensure code
 * coverage, and prevent regressions. All Apex classes are
 * required to have at least 75% code coverage in order to be deployed
 * to a production organization. In addition, all triggers must have some code coverage.
 * 
 * The @isTest class annotation indicates this class only contains test
 * methods. Classes defined with the @isTest annotation do not count against
 * the organization size limit for all Apex scripts.
 *
 * See the Apex Language Reference for more information about Testing and Code Coverage.
