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)
