Hi

I am new to test classes. I have made controller which contain only querries. I need help to make a test class of it.

what should be the approach?

///////////////////////controller///////////////////////////////////////

public with sharing class Bcaformatcontroller{

public String workstations { get; set; }
public date today{get;set;}
public String offerID = ApexPages.currentPage().getParameters().get('Id');
public List <RealSteer__LeaseOffer__c> records {get;set;}
public List<Contact> licenseeCon {get;set;}
public List<AccountContactRole> licenseeConID {get;set;}
public List<AccountContactRole> licensorConID {get;set;}
public List<Contact> licensorCon {get;set;}
public List<Services__c> charge{get; set;}
public List<Services__c> chargeParking{get; set;}
public String pdfURL{get;set;}

public Bcaformatcontroller(){
today = System.today();
records = [Select r.Deposit_ask_for__c, r.Start_Date__c, r.RealSteer__Property__r.Name,RealSteer__Property__r.RealSteer__Street__c,RealSteer__Property__r.RealSteer__City__c,
RealSteer__Property__r.RealSteer__State__c,RealSteer__Property__r.RealSteer__Country__c, Offer_Through__c, RealSteer__Property__r.Account__c,
r.RealSteer__Property__c, r.Name, r.Id, r.End_Date1__c, r.Duration__c,Company_Name__r.Name,r.RealSteer__Property__r.Total_L_Shaped__c, r.RealSteer__Property__r.Total_Linear__c,
r.Company_Name__c, Broker_Name__c,Company_Name__r.BillingCountry,Company_Name__r.BillingPostalCode,
Company_Name__r.BillingState,Company_Name__r.BillingCity,Company_Name__r.BillingStreet ,r.Lock_In_Period__c, r.Notice_Period__c
From RealSteer__LeaseOffer__c r where id = :offerID];

licenseeConID = [SELECT ContactId FROM AccountContactRole WHERE (IsPrimary =: true AND AccountId =: records[0].Company_Name__c)];
licenseeCon = [Select LastName,Phone,Fax, FirstName, Salutation From contact where id =: licenseeConID[0].ContactId ];

licensorConID = [SELECT ContactId FROM AccountContactRole WHERE (IsPrimary =: true AND AccountId =: records[0].RealSteer__Property__r.Account__c)];
licensorCon = [Select LastName,Phone,Fax, FirstName, Salutation From contact where id =: licensorConID[0].ContactId ];

charge = [Select Charges_Per_Hour__c from Services__c where (Business_Center_Name__c = :records[0].Company_Name__c AND RecordTypeid in(select id from recordtype where name = : 'Internet Services'))];
chargeParking = [Select Parking_Rate__c from Services__c where (Business_Center_Name__c = :records[0].Company_Name__c AND RecordTypeid in(select id from recordtype where name = : 'Parking'))];


}

}
