likely running with a trimmed kernel where the symbols are not available.
Run with a "no trim" kernel.
Check the test module dependency with `modinfo <module_name>.ko` on your local
host machine or on the Android device with `adb shell modinfo <module_name.ko>`.
All dependent modules need to be installed before the test module can be
installed successfully.
Check if the module is already installed with `adb shell lsmod`. The `adb shell
rmmod` can be used to remove the already installed test module, and installing
the test module again will trigger the test rerun.
`adb shell lsmod` will also show the module dependency for your test module in
the `Used by` column. You can not remove a module with `adb shell rmmod` if it
is being used by another module. Other modules that are using it need to be
removed first.

Check dmesg for KUnit errors.
$ dmesg | grep kunit
If "kunit: disabled" is shown then `kunit.enable=1` has not been set.
If "kunit: disabled" is shown then kunit.ko is not installed with `enable=1`.
If kunit.ko or kunit_<*test>.ko fails to install, check for whether they are
already installed with `adb shell lsmod`.
