# 1. INTRODUCTION
#
# This module defines a unit test for the keyword_translator class.
#
# It uses the PyUnit unit test framework [PyUnit].
#
# The intended readership is project developers.
#
# This document is not confidential.

# 2. KEYWORD TRANSLATOR TEST CASES


# 2.1. Single characters in the defect tracker
#
# Test that all single characters are unchanged when translated from the
# defect tracker to Perforce and back again.

# 2.2. Characters in Perforce
#
# Test that legal keyword characters (except backslash) in Perforce are
# unchanged when translated to the defect tracker and back again.
#
# Perforce job field names can't contain whitespace, hashes, or double
# quotes.  Values in "select" fields in Perforce jobspecs also can't

# 3. NULL TRANSLATOR TEST CASES
#
# Test that the null translator (translator.translator) does nothing.
