    static void testApexPageMessages(){
        Test.startTest();

         //CreateOrderFromQuote s = new CreateOrderFromQuote();    
        CreateOrderFromQuote.UpdateStatusField(q.Id);
        Test.stopTest();
    }
}

This is my test class.
I'm getting the error:

Test class containing a test setup method cannot have any methods
annotated with @isTest(​SeeAllData=​true)

I need seeattdata=true as i;m using standard pricebbok2.
can someone help me how to solve the issue?
