Hi,
Inserting the 'nfit_test' module in a natural way fails with the following error:
$ sudo modprobe -v nfit_test
insmod /lib/modules/5.6.0-rc1-bb-13504-g7b27a8622f80/kernel/drivers/char/hw_random/rng-core.ko.xz

It is because the standard versions of the 'libnvdimm' and 'nfit' modules were inserted instead of the mocked ones from the 'extra' subdirectory as you can see above and below:
$ sudo modinfo nfit | grep -e filename
filename: /lib/modules/5.6.0-rc1-bb-13504-g7b27a8622f80/kernel/drivers/acpi/nfit/nfit.ko.xz
$ sudo modinfo libnvdimm | grep -e filename
filename: /lib/modules/5.6.0-rc1-bb-13504-g7b27a8622f80/kernel/drivers/nvdimm/libnvdimm.ko.xz
There is a workaround - it can be done manually in the following way....
$ sudo rmmod nfit
$ sudo rmmod libnvdimm
Only /lib/modules/5.6.0-rc1-bb-13504-g7b27a8622f80/extra/test/nfit_test_iomap.ko.xz is inserted now.
$ sudo insmod /lib/modules/5.6.0-rc1-bb-13504-g7b27a8622f80/extra/libnvdimm.ko.xz
$ sudo insmod /lib/modules/5.6.0-rc1-bb-13504-g7b27a8622f80/extra/nd_btt.ko.xz

Let's try to remove the 'nfit_test' module:
$ sudo ndctl disable-region all
disabled 8 regions
$ sudo modprobe -v -r nfit_test
rmmod nfit_test
rmmod nfit
... and insert it again:
$ sudo modprobe -v nfit_test
insmod /lib/modules/5.6.0-rc1-bb-13504-g7b27a8622f80/kernel/drivers/acpi/nfit/nfit.ko.xz
insmod /lib/modules/5.6.0-rc1-bb-13504-g7b27a8622f80/extra/test/nfit_test.ko.xz
modprobe: ERROR: could not insert 'nfit_test': Unknown symbol in module, or unknown parameter (see dmesg)
$ dmesg | tail
[ 1486.193503] nfit_test: Unknown symbol acpi_nfit_test (err -2)
And now the wrong version of the 'nfit' module was inserted ...
The only way is to do it manualy again:
$ sudo rmmod -v nfit
$ sudo insmod /lib/modules/5.6.0-rc1-bb-13504-g7b27a8622f80/extra/nfit.ko.xz
$ sudo modprobe -v nfit_test
insmod /lib/modules/5.6.0-rc1-bb-13504-g7b27a8622f80/extra/test/nfit_test.ko.xz
Does anyone know how it can be fixed? Any suggestions?

Yes, you're environment is not being careful to exclude the production
version of the modules from being loaded. The ndctl unit test core
also sanity checks nfit_Test and reports the collisions before running
tests. See nfit_test_init():
https://github.com/pmem/ndctl/blob/master/test/core.c#L119
I'd recommend at least running:
make TESTS=libndctl check
...from latest ndctl.git to sanity check your nfit_test module
dependencies before trying to load it manually.
See the troubleshooting document:
https://github.com/pmem/ndctl#troubleshooting
...for other tips about how to prevent the production modules from loading.

Thanks for tips! I have followed those instructions and it did not help:

As you can see 'ndctl' also cannot load the extra test version of the modules even if there is the following file:

override nfit * extra
override device_dax * extra
override dax_pmem * extra

override nd_btt * extra
override nd_e820 * extra

Can I try anything else? Do you have any suggestions?

Do you have the nfit, or libnvdimm modules loading from the initramfs?

No, I do not:
$ sudo lsinitrd /boot/initramfs-5.6.0-rc1-13504-g7b27a8622f80.img | grep nfit
$ sudo lsinitrd /boot/initramfs-5.6.0-rc1-13504-g7b27a8622f80.img | grep libnvdimm
