# This is a test suite for Kconfiglib. 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 arguments. With no argument, # they default to off. # # - speedy: # Run scripts/kconfig/conf directly when comparing outputs instead of using # 'make' targets. Makes things a lot faster, but could break if Kconfig # files start depending on additional environment variables besides ARCH and # SRCARCH. (These would be set in the Makefiles in that case.) Safe as of # Linux 3.7.0-rc8. # # - obsessive: # By default, only valid arch/defconfig pairs will be tested. With this # enabled, every arch will be tested with every defconfig, which increases # the test time by an order of magnitude. Occasionally finds (usually very # obscure) bugs, and I make sure everything passes with it. # # - log: # Log timestamped failures of the defconfig test to test_defconfig_fails in # the root. Especially handy in obsessive mode. # # For example, to run in speedy mode with logging, run # # $ python Kconfiglib/testsuite.py speedy log # # (PyPy also works, and runs the defconfig tests roughly 20% faster on my # machine. Some of the other tests get an even greater speed-up.) # # The tests have been roughly arranged in order of time needed. # # All tests should pass.
