@istest
private class TestWarehouseUtils{
    static testMethod void testFindWarehousesWithinTwentyMiles() {
    String myLat = '17.4368';
    String myLon = '78.4439';
    Warehouse__c closestWarehouse = createClosestTestWarehouse();
   Warehouse__c closeWarehouse = createCloseTestWarehouse();
   Warehouse__c tooFarWarehouse = createTooFarTestWarehouse();
List<Warehouse__c> nearbyWarehouse =
    WarehouseUtils.findNearbyWarehouse(myLat, myLon);
    Test.stopTest();
System.assert(nearbyWarehouse.size() == 2);
System.assert(nearbyWarehouse[0].Name == closestWarehouse.Name);
System.assert(nearbyWarehouse[1].Name == closeWarehouse.Name);
    if(0 < nearbyWarehouse.size()) {
    for (Warehouse__c wh : nearbyWarehouse) {
        System.assert(wh.Name != tooFarWarehouse.Name);} 
           {

Hi Mukesh,
Looks like a formatting issue around the closing of your brackets and the next method

Change lines 18-19 from:
System.assert(wh.Name != tooFarWarehouse.Name);} 
           {

To:
System.assert(wh.Name != tooFarWarehouse.Name);} 
           }
}

Hope that helps,
Richard Jimenez

There were some additional braces in your class which were causing issue. Try with above code.

Change warehouse_c to warehouse__c.
Make sure this custom object exists.
Pankaj_GanwaniPankaj_Ganwani
Use warehouse__c at line no 42, 47 and 52 as return type, since we are using custom object.
mukesh nanimukesh nani
still same error is coming error is - Invalid type: warehouse_c
Pankaj_GanwaniPankaj_Ganwani
Just check whether Warehouse object exist in org or not? If it does not exist, then firstly create it with the fields which have been referred in the code and then try to save the class. I made some edits in your code.
