    5 # This script runs end-to-end testcase for search
    6 #
    7 # Notes to students:
    8 #
    9 # 1. Purpose of this script is to illustrate how fragile end-to-end automation is.
   10 # 2. This script will show you only GENERAL PRINCIPLE about how to automate regression testing
   11 # 3. If you ever decide to launch full scale automation project, put a lot of thinking if it's worth it.
