No more than one executeBatch can be called from within a test method

Question

This is my test method for batch process:

static testMethod void TST_testBatch() {

    Test.startTest();
    testBatch b = new testBatch();
    Database.executeBatch(b);
    Test.stopTest();    
}

But I am getting this exception:

System.UnexpectedException: No more than one executeBatch can be called from within a test method. Please make sure the iterable returned from your start method matches the batch size, resulting in one executeBatch invocation.

I have @isTest(SeeAllData=false) at top, but cannot figure out what is causing this error.

UPDATE: I have even kept finish methods as shown below:

global void finish(Database.BatchableContext BC){
    if(!Test.isRunningTest())
     Database.executeBatch(new testBatch()));
}

UPDATE 2:

testBatch execute method:

global void execute(Database.BatchableContext BC, List<sObject> scope){
    Map<Id,SomeOnject> ms = new Map<Id,SomeOnject>();
    for(sObject s: scope)
        ms.put(s.Id,(SomeOnject)s);
    if(ms.size() > 0){
        Map<Id,SomeOnject> toUpdate = new Map<Id,SomeOnject>();
        SomeOnject tmp;
        for(Territory__c t: [SE********************************]){
            tmp = ms.get(t.SFDC__c);
            tmp.SFDCTerritory__c = t.Id;
            tmp.Territory_Nr__c = t.TerritoryNr__c;
            tmp.Territory_Account__c = t.Territory_Account__c; 
            toUpdate.put(tmp.Id,tmp);
        }

        if(toUpdate.size() > 0){
            TerritoryUtils.runUpdateSFDC = false; 
            update toUpdate.values();
        }
    }
}

Start Method:

 global Database.QueryLocator start(Database.BatchableContext BC){
    String query = 'SELECT *************';
    return Database.getQueryLocator(query);
}

Answer 1

It looks like you're querying on a Setup object (one not affected by SeeAllData=false), so you'll need to limit your query:

global Database.QueryLocator start(Database.BatchableContext BC){
    String query = 'SELECT *************'+(Test.isRunningTest()?' LIMIT 200':'');
    return Database.getQueryLocator(query);
}
