I would swear my test was working before but now it's not and I can't figure out why.  Thoughts?  Here's my test... pretty simple. 

This process works in my Sandbox, it just want test properly when I try to push it to prod. 


@isTest
public class RetrieveLaneDetailTest {
     
    @isTest public static void lanerates() {
        LaneDetailCon laneDetail = new LaneDetailCon();
        PageReference page = laneDetail.executeSearch();
        System.assert(true);
    }
}

Here's my controller:  
public with sharing class LaneDetailCon {
    
    public String oCity { get; set; }
    public String dCity { get; set; }
    public String rType { get; set; }
    public Boolean searched {get; set;}
    
    public List<Lane_Detail__C> lanes { get; set; }
        
public LaneDetailCon(){ 
    searched=false;    
        String orCity = ApexPages.currentPage().getParameters().get('oCity');
        String dsCity = ApexPages.currentPage().getParameters().get('dCity'); 
        String recType = ApexPages.currentPage().getParameters().get('rType');   
        if (null!=orCity)
        {
            oCity = orCity;
            dCity = dsCity;
            rType = recType;
            executeSearch();
        }
    }
    
public PageReference executeSearch(){
    searched=true;
        
           lanes =  [SELECT id, Origin_City__c, Origin_Statess__c, Destination_City__c, Destination_States__c, Rate__c, 
                             RecordTypeId, Rate_10K__c, Rate_30K__c, CPBD_10K__c, CPBD_30K__c,
                             Opportunity__r.Name, Opportunity__r.AccountId, Opportunity__r.Date_Quoted__c, Opportunity__r.StageName 
                     FROM Lane_Detail__c
                     WHERE Origin_City__c = :oCity AND Destination_City__c = :dCity AND RecordTypeId = :rType
                     Order By Opportunity__r.Date_Closed__c Desc
                     LIMIT 25]; 

        return null;
    }
}
