# This is the Kconfiglib test suite. It runs selftests on Kconfigs provided by
# us and tests compatibility with the C Kconfig implementation by comparing the
# output of Kconfiglib with the output of the scripts/kconfig/*conf utilities
# for different targets and defconfigs. It should be run from the top-level
# kernel directory with
#
# $ python Kconfiglib/testsuite.py
#
# Some additional options can be turned on by passing them as arguments. They
# default to off.
#
# - obsessive:
# By default, only valid arch/defconfig pairs are tested. In obsessive mode,
# every arch will be tested with every defconfig. Increases the testing time
# by an order of magnitude. Occasionally finds (usually obscure) bugs, and I
# make sure everything passes with it.
#
# - obsessive-min-config:
# Like obsessive, for the minimal configuation (defconfig) tests.
#
# - log:
# Log timestamped defconfig test failures to the file test_defconfig_fails.
# Handy in obsessive mode.
#
# For example, this commands runs the test suite in obsessive mode with logging
# enabled:
#
# $ python(3) Kconfiglib/testsuite.py obsessive log
#
# pypy works too, and runs most tests much faster than CPython.
#
# All tests should pass. Report regressions to ulfalizer a.t Google's email
# service.
