# Wireshark/TShark Regression Testing
#
# This is a sample Makefile for regression testing of the
# Wireshark engine. These tests use that uses 'tshark -V' to analyze all
# the frames of a capture file.
#
# You should probably rename this file as 'Makefile' in a separate directory
# set aside for the sole purpose of regression testing. Two text files will
# be created for each capture file you test, so expect to have lots of files.
#
# Set TSHARK, CAPTURE_DIR, and CAPTURE_FILES to values appropriate for
# your system. Run 'make' to create the initial datasets. Type 'make accept'
# to accept those files as the reference set.
#
# After you make changes to TShark, run 'make regress'. This will re-run
# the tests and compare them against the accepted reference set of data.
# The comparison, which is just an invocation of 'diff -u' for the output
# of each trace file, will be put into a file called 'regress'. Examine
# this file for any changes that you did or did not expect. 
#
# If you have introduced a change to TShark that shows up in the tests, but
# it is a valid change, run 'make accept' to accept those new data as your
# reference set. 
#
# Commands:
#
# 'make'                Creates tests
# 'make regress'        Checks tests against accepted reference test results
#                       Report is put in file 'regress'
# 'make accept'         Accept current tests; make them the reference test results
# 'make clean'          Cleans any tests (but not references!)
