# Purpose:
# The purpose of this script is to convert uses of tests as filters to proper jinja test syntax
# as part of https://github.com/ansible/proposals/issues/83
# Notes:
# This script is imperfect, but was close enough to "fix" all integration tests
# with the exception of:
#
# 1. One file needed manual remediation, where \\\\ was ultimately replace with \\ in 8 locations.
# 2. Multiple filter pipeline is unsupported. Example:
# var|string|search('foo')
# Which should be converted to:
# var|string is search('foo')
