The latest clock test indeed does not have this test present; I did run a similar one and it worked fine:

That said; I did have some tests fail and this is what I saw in the app's logs:
(process:2540): dconf-CRITICAL **: unable to create file '/run/user/32011/dconf/user': Permission denied.  dconf will not work properly.
