 """Encapsulates running tests defined in tests.py.
 
 Running this script requires passing --config-path with a path to a config file
 of the following structure:
 
   [data_files]
   passwords_path=<path to a file with passwords>
   [binaries]
   chrome-path=<chrome binary path>
   chromedriver-path=<chrome driver path>
   [run_options]
   # |tests_in_parallel| is optional, the default value is 1.
   tests_in_parallel=<number of parallel tests>
   # |tests_to_runs| field is optional, if it is absent all tests will be run.
   tests_to_run=<test names to run, comma delimited>
+  # |test_cases_to_run| field is optional, if it is absent all test cases
+  # will be run.
+  test_cases_to_run=<test names to run, comma delimited>
   [logging]
   # |save-only-failures| is oprional, the default is false.
   save-only-failures=<boolean parameter which enforces saving results of only
                       failed tests>
 
 The script uses the Python's logging library to report the test results,
 as well as debugging information. It emits three levels of logs (in
 descending order of severity):
   logging.INFO: Summary of the tests.
   logging.DEBUG: Details about tests failures.
