#============================================================
#  Author: John Theofanopoulos
#  A simple parser. Takes the output files generated during the
#  build process and extracts information relating to the tests.
#
#  Notes:
#    To capture an output file under VS builds use the following:
#      devenv [build instructions] > Output.txt & type Output.txt
#
#    To capture an output file under Linux builds use the following:
#      make | tee Output.txt
#
#    This script can handle the following output formats:
#    - normal output (raw unity)
#    - fixture output (unity_fixture.h/.c)
#    - fixture output with verbose flag set ("-v")
#    - time output flag set (UNITY_INCLUDE_EXEC_TIME define enabled with milliseconds output)
#
#    To use this parser use the following command
#    ruby parseOutput.rb [options] [file]
#        options: -xml  : produce a JUnit compatible XML file
#                 -suiteRequiredSuiteName
#                       : replace default test suite name to
#                           "RequiredSuiteName" (can be any name)
#           file: file to scan for results
