1. Setup VM with:

  • CPU - 4

  • Memory - 8GB

  • Hard disk - 100GB

  • Have to use DEBUG build, where we have debug macro

Setup process is described in this instruction.

Note : If you already created dilos_BASE BE according the instruction, and there is no any new tested stable version, just execute the following command:

beadm activate dilos_BASE

In other case if you have already the dilos_ISO_orig BE - make the command:

beadm activate dilos_ISO_orig

Then reboot and start the instruction from the section Step 6. Prepare VM for Tests Running:

reboot

If you have no one of these 2 BEs then start the instruction from the beginning.

Note : Create ztest user if you forgot to do it according the instruction:

sudo useradd -m -d /var/ztest -g staff -s /bin/bash ztest

sudo passwd ztest

echo "ztest ALL=(ALL:ALL) NOPASSWD: ALL" >> /etc/sudoers.d/ztest

2. Install packages for LIBC tests:

Note : If you already did it on the previous step when preparing VM to run, then you can skip this step and go to the next one.

sudo apt update reboot sudo apt install system-test-libctest testrunner python3 build-essential

3. Login by user ztest and run tests:

sudo /opt/libc-tests/bin/libctest

Wait for about 5 minutes and found full logs at:

/var/tmp/test_results/<ISO TIME>

Run in stability mode
