# A script to do a framework for weave session testing
#
# This script shows the recommended style for scripts, with a
# TestRunner class. The script is executed just once by each worker
# process and defines the TestRunner class. The Grinder creates an
# instance of TestRunner for each worker thread, and repeatedly calls
# the instance for each run of that thread.

# Detailed documentation can be found at https://wiki.mozilla.org/Labs/Weave/GrinderTesting
