kunit: tool: add Python wrappers for running KUnit tests 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>

kunit: Run all KUnit tests through allyesconfig Implemented the functionality to run all KUnit tests through kunit_tool by specifying an --alltests flag, which builds UML with allyesconfig enabled, and consequently runs every KUnit test. A new function was added to kunit_kernel: make_allyesconfig. Firstly, if --alltests is specified, kunit.py triggers build_um_kernel which call make_allyesconfig. This function calls the make command, disables the broken configs that would otherwise prevent UML from building, then starts the kernel with all possible configurations enabled. All stdout and stderr is sent to test.log and read from there then fed through kunit_parser to parse the tests to the user. Also added a signal_handler in case kunit is interrupted while running. Tested: Run under different conditions such as testing with --raw_output, testing program interrupt then immediately running kunit again without --alltests and making sure to clean the console.

kunit: tool: add Python wrappers for running KUnit tests 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>

kunit: Run all KUnit tests through allyesconfig Implemented the functionality to run all KUnit tests through kunit_tool by specifying an --alltests flag, which builds UML with allyesconfig enabled, and consequently runs every KUnit test. A new function was added to kunit_kernel: make_allyesconfig. Firstly, if --alltests is specified, kunit.py triggers build_um_kernel which call make_allyesconfig. This function calls the make command, disables the broken configs that would otherwise prevent UML from building, then starts the kernel with all possible configurations enabled. All stdout and stderr is sent to test.log and read from there then fed through kunit_parser to parse the tests to the user. Also added a signal_handler in case kunit is interrupted while running. Tested: Run under different conditions such as testing with --raw_output, testing program interrupt then immediately running kunit again without --alltests and making sure to clean the console.
