After having most test failed suddenly for no apparent reason, we found that the culprit was that a field we were using to search for a special user was changed to be unique. 

User[] users = [select id from User where Unique_Field___c = :'Special' limit 1];
System.assert(users.size()>0, 'Missing Special user configuration.');

 If I run the code in a test method, I get 'Missing Special user configuration.' assert exception. If I run it in a developer console, it runs without the assert triggering.

Any ideas why is this? Is it a bug or feature? Is it documented anywhere?

Hello ,

              I recently started developing in Apex with .net background and I am looking for insight to solve the below problem.

I have 30K carriers(Account) objects and need to update them on a nightly basis from a webservice (like insurance etc ).

I was able to successfully implement the webservice and update a single account but now I have to do that in a batch

Class UpdateService-- Take AccountObject and gets the latest information and does a DML.

ClassBatchAccounts--Gets the list of all Accounts and pass each account to above class

ClasScheduleBatch--Call above BatchAccounts(every day inthe morning).

When i implement this i am getting too many callouts.

I need to call webservice for each account so how can i do that in ApexBatch?

Any insight would be helpfull...
