# The focus of this file is testing the CLI shell tool.
# These tests are specific to the .stats command.
#
# 2015-03-19:  Added tests for .trace

# Test plan:
#
#   shell4-1.*: Basic tests specific to the "stats" command.
#   shell4-2.*: Basic tests for ".trace"
#   shell4-3.*: The ".read" command takes the shell out of interactive mode
