I am trying to deploy a trigger to a production environment.

The trigger was created directly within Salesforce (Setup|Crate|Object|Trigger|Button New).
After a long search I decided to install eclipse with Fore.com IDE plugin.

After check in the sandbox version I did some changes on the trigger and save it back to sandbox. It works fine.

Using the deploy wizard within the IDE (Force.com|Deploy to Server ...) does not work.

I guess I need a testclass but I have no idea how to do this and where I have to save this testclass.
Is there a simple step-by-step instuction.

Another problem is that field names and object names between sandbox and production environment differ.
So I have to change some field and object names before deploy the trigger to production environment.
I do not know I that causes any problem.

The trigger:

Trigger checkTrialProductAvailable on Trial_Connect_del__c (before insert,before update) { List<ID> TrialProductIDs = new List<ID>{}; List<ID> TrialIDs = new List<ID>{}; for(Trial_Connect_del__c objTrial_Connect : Trigger.new){ if(objTrial_Connect.Trial_Product_RoW__c != null){ TrialProductIDs.add(objTrial_Connect.Trial_Product_RoW__c); TrialIDs.add(objTrial_Connect.Trial_ROW__c); } } if(TrialProductIDs.size() > 0){ if(TrialProductIDs.size() == 1){ ID myCurrentT_Id = TrialIDs.get(0); Trial_ROW__c myCurrentTrialObj = [SELECT Trial_Actual_Ship_Date__c, Verf_gbar_ab__c FROM Trial_ROW__c T WHERE T.ID = : myCurrentT_Id]; Date myCurrentTrial_Actual_Ship_Date = myCurrentTrialObj.Trial_Actual_Ship_Date__c; Date myCurrentTrial_Verf_gbar_ab_Date = myCurrentTrialObj.Verf_gbar_ab__c; Map<ID,Trial_Connect_del__c> mapTrial_ConnectFields = new Map<ID,Trial_Connect_del__c>([ Select Id, Trial_ROW__c, Trial_Product_RoW__c From Trial_Connect_del__c Where Trial_Product_RoW__c in :TrialProductIDs]); List<ID> myList = new List<ID>(mapTrial_ConnectFields.keySet()); Trial_Connect_del__c myTC; Trial_ROW__c myT; ID myIdT; List<ID> listTrialID = new List<ID>(); for(ID myID : myList){ myTC = mapTrial_ConnectFields.get(myID); myIdT = myTC.Trial_ROW__c; if(myIdT != null){ listTrialID.add(myIdT); } } List<Trial_ROW__c> objListTrial = new List<Trial_ROW__c>(); objListTrial = [SELECT T.Name FROM Trial_ROW__c T WHERE (T.ID IN :listTrialID) AND ((T.Verf_gbar_ab__c > :myCurrentTrial_Actual_Ship_Date) AND (T.Trial_Actual_Ship_Date__c < :myCurrentTrial_Verf_gbar_ab_Date)) ]; List<String> listStrTrialName = new List<String>(); for(Trial_ROW__c objTrialName : objListTrial){ listStrTrialName.add(objTrialName.Name); } if(listStrTrialName.isEmpty() == false){ Trial_Connect_del__c objTrial_Connect2 = trigger.new[0]; objTrial_Connect2.addError('Trial Product is occupied by other Trial(s) ' + listStrTrialName); } } else{ Trial_Connect_del__c objTrial_Connect3 = trigger.new[0]; objTrial_Connect3.addError('Unexpected count of Trial Products!'); } } }
