path: root/tests/test_pretty_print.py

#!/usr/bin/python
#
# this program reads the ctest logfiles from builddir/Testing/Temporary
# and generates two 'pretty printed' outputs in that directory:
#
# 1. mediawiki format, for uploading to a wiki.
#    automated uploading is available by following these steps:
# 
#  download mwclient
#  python ctest_pretty_print.py --upload 
#
# 2. html format, for easy local viewing
#
# sysinfo.txt:
#   sysinfo.txt should have been created by ctest by the main test run. 
#   it is the output of opencsgtest --info 


# todo
# 1. add sysinfo about ... git branch
# 2. consolidate image flip
# 3. uploading, can it be done in one file
# 4. consolidate pretty print
