The ultimate goal is to create minimal isolated test binaries; in the meantime we are using UML to provide the infrastructure to run tests, so define an abstract way to configure and run tests that allow us to change the context in which tests are built without affecting the user. This also makes pretty and dynamic error reporting, and a lot of other nice features easier. kunit_config.py: - parse .config and Kconfig files. kunit_kernel.py: provides helper functions to: - configure the kernel using kunitconfig. - build the kernel with the appropriate configuration. - provide function to invoke the kernel and stream the output back. kunit_parser.py: parses raw logs returned out by kunit_kernel and displays them in a user friendly way. test_data/*: samples of test data for testing kunit.py, kunit_config.py, etc. Signed-off-by: Felix Guo <felixguoxiuping@gmail.com> Signed-off-by: Brendan Higgins <brendanhiggins@google.com> Reviewed-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org> Reviewed-by: Logan Gunthorpe <logang@deltatee.com> Reviewed-by: Stephen Boyd <sboyd@kernel.org> Signed-off-by: Shuah Khan <skhan@linuxfoundation.org>
