The current kunit execution model is to provide base kunit functionality and tests built-in to the kernel. The aim of this series is to allow building kunit itself and tests as modules. This in turn allows a simple form of selective execution; load the module you wish to test. In doing so, kunit itself (if also built as a module) will be loaded as an implicit dependency. Because this requires a core API modification - if a module delivers multiple suites, they must be declared with the kunit_test_suites() macro - we're proposing this patch set as a candidate to be applied to the test tree before too many kunit consumers appear. We attempt to deal with existing consumers in patch 3. Changes since v3: - removed symbol lookup patch for separate submission later - removed use of sysctl_hung_task_timeout_seconds (patch 4, as discussed with Brendan and Stephen) - disabled build of string-stream-test when CONFIG_KUNIT_TEST=m; this is to avoid having to deal with symbol lookup issues - changed string-stream-impl.h back to string-stream.h (Brendan) - added module build support to new list, ext4 tests Changes since v2: - moved string-stream.h header to lib/kunit/string-stream-impl.h (Brendan) (patch 1) - split out non-exported interfaces in try-catch-impl.h (Brendan) (patch 2) - added kunit_find_symbol() and KUNIT_INIT_SYMBOL to lookup non-exported symbols (patches 3, 4) - removed #ifdef MODULE around module licenses (Randy, Brendan, Andy) (patch 4) - replaced kunit_test_suite() with kunit_test_suites() rather than supporting both (Brendan) (patch 4) - lookup sysctl_hung_task_timeout_secs as kunit may be built as a module and the symbol may not be available (patch 5) Alan Maguire (6): kunit: move string-stream.h to lib/kunit kunit: hide unexported try-catch interface in try-catch-impl.h kunit: allow kunit tests to be loaded as a module kunit: remove timeout dependence on sysctl_hung_task_timeout_seconds kunit: allow kunit to be loaded as a module kunit: update documentation to describe module-based build Documentation/dev-tools/kunit/faq.rst | 3 +- Documentation/dev-tools/kunit/index.rst | 3 + Documentation/dev-tools/kunit/usage.rst | 16 ++ fs/ext4/Kconfig | 2 +- fs/ext4/Makefile | 5 + fs/ext4/inode-test.c | 4 +- include/kunit/assert.h | 3 +- include/kunit/string-stream.h | 51 ----- include/kunit/test.h | 35 +++- include/kunit/try-catch.h | 10 - kernel/sysctl-test.c | 4 +- lib/Kconfig.debug | 4 +- lib/kunit/Kconfig | 6 +- lib/kunit/Makefile | 14 +- lib/kunit/assert.c | 10 + lib/kunit/example-test.c | 88 --------- lib/kunit/kunit-example-test.c | 90 +++++++++ lib/kunit/kunit-test.c | 334 ++++++++++++++++++++++++++++++++ lib/kunit/string-stream-test.c | 5 +- lib/kunit/string-stream.c | 3 +- lib/kunit/string-stream.h | 51 +++++ lib/kunit/test-test.c | 331 ------------------------------- lib/kunit/test.c | 25 ++- lib/kunit/try-catch-impl.h | 28 +++ lib/kunit/try-catch.c | 37 +--- lib/list-test.c | 4 +- 26 files changed, 628 insertions(+), 538 deletions(-) delete mode 100644 include/kunit/string-stream.h delete mode 100644 lib/kunit/example-test.c create mode 100644 lib/kunit/kunit-example-test.c create mode 100644 lib/kunit/kunit-test.c create mode 100644 lib/kunit/string-stream.h delete mode 100644 lib/kunit/test-test.c create mode 100644 lib/kunit/try-catch-impl.h -- 1.8.3.1
