Currently, kunit_parser.py is stripping all leading whitespace to make parsing easier. But this means we can't accurately show kernel output for failing tests or when the kernel crashes. Embarassingly, this affects even KUnit's own output, e.g. [13:40:46] Expected 2 + 1 == 2, but [13:40:46] 2 + 1 == 3 (0x3) [13:40:46] not ok 1 example_simple_test [13:40:46] [FAILED] example_simple_test After this change, here's what the output in context would look like [13:40:46] =================== example (4 subtests) =================== [13:40:46] # example_simple_test: initializing [13:40:46] # example_simple_test: EXPECTATION FAILED at lib/kunit/kunit-example-test.c:29 [13:40:46] Expected 2 + 1 == 2, but [13:40:46] 2 + 1 == 3 (0x3) [13:40:46] [FAILED] example_simple_test [13:40:46] [SKIPPED] example_skip_test [13:40:46] [SKIPPED] example_mark_skipped_test [13:40:46] [PASSED] example_all_expect_macros_test [13:40:46] # example: initializing suite [13:40:46] # example: pass:1 fail:1 skip:2 total:4 [13:40:46] # Totals: pass:1 fail:1 skip:2 total:4 [13:40:46] ===================== [FAILED] example ===================== This example shows one minor cosmetic defect this approach has. The test counts lines prevent us from dedenting the suite-level output. But at the same time, any form of non-KUnit output would do the same unless it happened to be indented as well.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
