KUnit has support for setup/cleanup logic for each test case in a suite. But it lacks the ability to specify setup/cleanup for the entire suite itself. This can be used to do setup that is too expensive or cumbersome to do for each test. Or it can be used to do simpler things like log debug information after the suite completes. It's a fairly common feature, so the lack of it is noticeable. Some examples in other frameworks and languages: * https://docs.python.org/3/library/unittest.html#setupclass-and-teardownclass * https://google.github.io/googletest/reference/testing.html#Test::SetUpTestSuite Meta: This is very similar to this patch here: https://lore.kernel.org/linux-kselftest/20210805043503.20252-3-bvanassche@acm.org/ The changes from that patch: * pass in `struct kunit *` so users can do stuff like `kunit_info(suite, "debug message")` * makes sure the init failure is bubbled up as a failure * updates kunit-example-test.c to use a suite init * Updates kunit/usage.rst to mention the new support * some minor cosmetic things * use `suite_{init,exit}` instead of `{init/exit}_suite` * make suite init error message more consistent w/ test init * etc. Signed-off-by: Daniel Latypov <dlatypov@google.com> Reviewed-by: David Gow <davidgow@google.com> Reviewed-by: Brendan Higgins <brendanhiggins@google.com> Signed-off-by: Shuah Khan <skhan@linuxfoundation.org>
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.
