Hello

We are looking for assistance on how to write a test class for the below code. If anyone could assist or direct me to another page that would be appreciated. We are using this lookup field and 'converting' it to a pick list type field for ease of use.

public class PropertyStagePL {

    private MyApp__Property__c property;
    public PropertyStagePL(ApexPages.StandardController controller) {
        this.property = (MyApp__Property__c)controller.getRecord();
    }
    public List <SelectOption> getStage {        
        Get{
            // GET CURRENT RECORD RECORD TYPE INFO 
            List<RecordType> bList = [SELECT Id, Name,SobjectType,DeveloperName
                FROM RecordType 
                WHERE Id =:property.RecordTypeId];  
            // FIND MATCHING STAGE RECORD TYPE FOR CURRENT RECORD
            List<RecordType> cList = [SELECT Id, Name,SobjectType,DeveloperName
                FROM RecordType 
                WHERE DeveloperName =:bList[0].DeveloperName AND SobjectType='MyStage__Stage__c'];
             
            List <SelectOption> stage = new List <SelectOption>();
            for( MyStage__Stage__c st: [SELECT Name, RecordType.Id, RecordType.Name, MyStage__Value__c, MyStage__Order_Number__c
                FROM MyStage__Stage__c 
                WHERE MyStage__Active__c = TRUE AND RecordTypeId = :cList[0].Id ORDER BY MyStage__Order_Number__c ASC ])
                stage.add(new selectOption(st.id, '('+st.MyStage__Order_Number__c +') '+st.MyStage__Value__c));
            return stage;
        }
        Set;
    }
}
