2019-10-07	kunit: Fix '--build_dir' option	SeongJae Park	1	-2/+4
	Running kunit with '--build_dir' option gives following error message: ``` $ ./tools/testing/kunit/kunit.py run --build_dir ../linux.out.kunit/ [00:57:24] Building KUnit Kernel ... [00:57:29] Starting KUnit Kernel ... Traceback (most recent call last): File "./tools/testing/kunit/kunit.py", line 136, in <module> main(sys.argv[1:]) File "./tools/testing/kunit/kunit.py", line 129, in main result = run_tests(linux, request) File "./tools/testing/kunit/kunit.py", line 68, in run_tests test_result = kunit_parser.parse_run_tests(kunit_output) File "/home/sjpark/linux/tools/testing/kunit/kunit_parser.py", line 283, in parse_run_tests test_result = parse_test_result(list(isolate_kunit_output(kernel_output))) File "/home/sjpark/linux/tools/testing/kunit/kunit_parser.py", line 54, in isolate_kunit_output for line in kernel_output: File "/home/sjpark/linux/tools/testing/kunit/kunit_kernel.py", line 145, in run_kernel process = self._ops.linux_bin(args, timeout, build_dir) File "/home/sjpark/linux/tools/testing/kunit/kunit_kernel.py", line 69, in linux_bin stderr=subprocess.PIPE) File "/usr/lib/python3.5/subprocess.py", line 947, in __init__ restore_signals, start_new_session) File "/usr/lib/python3.5/subprocess.py", line 1551, in _execute_child raise child_exception_type(errno_num, err_msg) FileNotFoundError: [Errno 2] No such file or directory: './linux' ``` This error occurs because the '--build_dir' option value is not passed to the 'run_kernel()' function. Consequently, the function assumes the kernel image that built for the tests, which is under the '--build_dir' directory, is in kernel source directory and finally raises the 'FileNotFoundError'. This commit fixes the problem by properly passing the '--build_dir' option value to the 'run_kernel()'.

2019-09-30	kunit: defconfig: add defconfigs for building KUnit tests	Brendan Higgins	3	-5/+29
	Add defconfig for UML and a fragment that can be used to configure other architectures for building KUnit tests. Add option to kunit_tool to use a defconfig to create the kunitconfig.

2019-09-30	kunit: tool: add Python wrappers for running KUnit tests	Felix Guo	12	-0/+1184
	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>
