The UT_TESTF_ macros read as 'unit test test flags' which is not right.
Rename to UTF ('unit test flags').
This has the benefit of being shorter, which helps keep UNIT_TEST()
declarations on a single line.
Give the enum a name and reference it from the UNIT_TEST() macros while
we are here.

Description
|
|
-----------
|
|
|
|
The ut command runs unit tests written in C.
|
|
|
|
Typically the command is run on :ref:`arch/sandbox/sandbox:sandbox` since it
|
|
includes a near-complete set of emulators, no code-size limits, many CONFIG
|
|
options enabled and runs easily in CI without needing QEMU. It is also possible
|
|
to run some tests on real boards.
|
|
|
|
For a list of available test suites, type `ut` by itself.
|
|
|
|
Each test is normally run once, although those marked with `UTF_DM` are
|
|
run with livetree and flattree where possible. To run a test more than once,
|
|
use the `-r` flag.
|
|
|
|
Manual tests are normally skipped by this command. Use `-f` to run them. See
|
|
See :ref:`develop/tests_writing:mixing python and c` for more information on
|
|
manual test.
|
|
|
|
When running unit tests, some may have side effects which cause a subsequent
|
|
test to break. This can sometimes be seen when using 'ut dm' or similar. To
|
|
fix this, select the 'one' test which breaks. Then tell the 'ut' command to
|
|
run this one test after a certain number of other tests have run. Using a
|
|
binary search method with `-I` you can quickly figure one which test is causing
|
|
the problem.
|
|
|
|
Generally all tests in the suite are run. To run just a single test from the
|
|
suite, provide the <test> argument.
|
|
|
|
See :ref:`develop/tests_writing:writing c tests` for more information on how to
|
|
write unit tests.

List available unit-test suites::
|
|
|
|
=> ut

|
|
<suite> Test suite to run, or all
|
|
|
|
Suites:
|
|
all - execute all enabled tests
