# __COPYRIGHT__
#
# runtest.py - wrapper script for running SCons tests
#
# This script mainly exists to set PYTHONPATH to the right list of
# directories to test the SCons modules.
#
# By default, it directly uses the modules in the local tree:
# ./src/ (source files we ship) and ./QMTest/ (other modules we don't).
#
# When any -p option is specified, this script assumes it's in a
# directory in which a build has been performed, and sets PYTHONPATH
# so that it *only* references the modules that have unpacked from
# the specified built package, to test whether the packages are good.
#
# Options:
#
#       -3              Run with the python -3 option,
#
#       -a              Run all tests; does a virtual 'find' for
#                       all SCons tests under the current directory.
#                       You can also specify a list of subdirectories
#                       (not available with the "--qmtest" option!). Then,
#                       only the given folders are searched for test files.
#
#       -d              Debug.  Runs the script under the Python
#                       debugger (pdb.py) so you don't have to
#                       muck with PYTHONPATH yourself.
#
#       -e              Starts the script in external mode, for
#                       testing separate Tools and packages.
#
#       -f file         Only execute the tests listed in the specified
#                       file.
#
#       -h              Print the help and exit.
#
#       -k              Suppress printing of count and percent progress for
#                       the single tests.
#
#       -l              List available tests and exit.
#
#       -n              No execute, just print command lines.
#
#       -o file         Save screen output to the specified log file.
#
#       -P Python       Use the specified Python interpreter.
#
#       -p package      Test against the specified package.
#
#       --passed        In the final summary, also report which tests
#                       passed.  The default is to only report tests
#                       which failed or returned NO RESULT.
#
#       -q              Quiet.  By default, runtest.py prints the
#                       command line it will execute before
#                       executing it.  This suppresses that print.
#
#       --quit-on-failure Quit on any test failure
#
#       -s              Short progress.  Prints only the command line
#                       and a percentage value, based on the total and
#                       current number of tests.
#                       All stdout and stderr messages get suppressed (this
#                       does only work with subprocess though)!
#
#       -t              Print the execution time of each test.
#
#       -X              The scons "script" is an executable; don't
#                       feed it to Python.
#
#       -x scons        The scons script to use for tests.
#
#       --xml file      Save test results to the specified file in an
#                       SCons-specific XML format.
#                       This is (will be) used for reporting results back
#                       to a central SCons test monitoring infrastructure.
#
# (Note:  There used to be a -v option that specified the SCons
# version to be tested, when we were installing in a version-specific
# library directory.  If we ever resurrect that as the default, then
# you can find the appropriate code in the 0.04 version of this script,
# rather than reinventing that wheel.)
