Hello Tom,

what I still do not understand why tests are sometimes skipped and
sometimes not for the same source code:

https://gitlab.denx.de/u-boot/u-boot/-/jobs/122018
Commit 7068e523

140 test/py/tests/test_efi_secboot/test_authvar.py .....
141 test/py/tests/test_efi_secboot/test_signed.py .....F
142 test/py/tests/test_efi_secboot/test_unsigned.py ...

https://gitlab.denx.de/u-boot/custodians/u-boot-efi/-/jobs/122155
Commit 7068e523

148 test/py/tests/test_efi_secboot/test_authvar.py sssss
149 test/py/tests/test_efi_secboot/test_signed.py ssssss
150 test/py/tests/test_efi_secboot/test_unsigned.py sss

Both runs used the same Docker image
trini/u-boot-gitlab-ci-runner:bionic-20200526-18Jun2020

What influence have different versions of the Gitlab runner?

gitlab-runner 13.1.1
gitlab-runner 12.2.0

Some of our tests create and delete files in /tmp. How are parallel jobs
separated in Gitlab?

Best regards

Heinrich
