Description

[Masayuki Nakano [:masayuki] (he/him)(JST, +0900)]

Probably starting from middle of last week, unexpected WPT results are not printed correctly due to the following error:

I updated MozillaBuild to 4.0.2, but IIRC, this happened before that.

[James Graham [:jgraham]]

Looks like we updating blessings/blessed recently, so probably a regression from that.

Comment 2

[Henrik Skupin [:whimboo][⌚️UTC+2]]

This doesn't only affect Windows but also Marionette tests on Mac OS, so it's not directly Mozilla build only.

Comment 3

[James Graham [:jgraham]]

I suspect this is a dupe of 1800494, but I'm not marking as such in case there turns out to be something testsuite specific that needs to happen.

This doesn't only affect Windows but also Marionette tests on Mac OS, so it's not directly Mozilla build only.

:ahochheiden, since you are the author of the regressor, bug 1744340, could you take a look? Also, could you set the severity field?
