12# This script is a copy of the chrome_tests.sh wrapper script with the following
13# changes:
14# - The locate_valgrind.sh of Chromium's Valgrind scripts dir is used to locate
15#   the Valgrind framework install. If it fails a fallback path is used instead
16#   (../../chromium/src/third_party/valgrind/linux_x64) and a warning message
17#   is showed by |show_locate_valgrind_failed_warning|.
18# - libyuv_tests.py is invoked instead of chrome_tests.py.
19# - Chromium's Valgrind scripts directory is added to the PYTHONPATH to make it
20#   possible to execute the Python scripts properly.
