Subject: [PATCH v3 kunit-next 0/2] kunit: add debugfs representation to show results/run tests
Date: Fri, 7 Feb 2020 16:58:12 +0000 [thread overview]
Message-ID: <1581094694-6513-1-git-send-email-alan.maguire@oracle.com> (raw)
When kunit tests are run on native (i.e. non-UML) environments, the results
of test execution are often intermixed with dmesg output. This patch
series attempts to solve this by providing a debugfs representation
of the results of the last test run, available as
/sys/kernel/debug/kunit/<testsuite>/results
Changes since v2:
- updated kunit_status2str() to kunit_status_to_string() and made it
static inline in include/kunit/test.h (Brendan)
- added log string to struct kunit_suite and kunit_case, with log
pointer in struct kunit pointing at the case log. This allows us
to collect kunit_[err|info|warning]() messages at the same time
as we printk() them. This solves for the most part the sharing
of log messages between test execution and debugfs since we
just print the suite log (which contains the test suite preamble)
and the individual test logs. The only exception is the suite-level
status, which we cannot store in the suite log as it would mean
we'd print the suite and its status prior to the suite's results.
(Brendan, patch 1)
- dropped debugfs-based kunit run patch for now so as not to cause
problems with tests currently under development (Brendan)
- fixed doc issues with code block (Brendan, patch 3)
Changes since v1:
- trimmed unneeded include files in lib/kunit/debugfs.c (Greg)
- renamed global debugfs functions to be prefixed with kunit_ (Greg)
- removed error checking for debugfs operations (Greg)
