I do the build for kunit test, like below.

mkdir ../kunit.out
echo "
CONFIG_KUNIT=y

CONFIG_DAMON=y
CONFIG_DAMON_KUNIT_TEST=y

CONFIG_DAMON_VADDR=y
CONFIG_DAMON_VADDR_KUNIT_TEST=y

CONFIG_DEBUG_FS=y
CONFIG_DAMON_DBGFS=y
CONFIG_DAMON_DBGFS_KUNIT_TEST=y
CONFIG_DAMON_PADDR=y" > ../kunit.out/.kunitconfig
./tools/testsing/kunit/kunit.py run --build_dir ../kunit.out
