2052314 - XPCShell tests handle tags inconsistently

Status: NEW

(Testing :: XPCShell Harness, defect)

Description

[Beatriz Rizental]

I noticed when using the multiple --tag arguments with XPCShell a match-all logic is applied -- the test must have all provided tags to be executed.

While mochi and marionette tests use a match-any logic.

Which is the correct? I believe it's match-any, since that is what the xpcshell argument docstring states: https://searchfox.org/firefox-main/source/testing/xpcshell/xpcshellcommandline.py#210-212

It's confusing also because somewhere in the code a docstring states "Multiple tag filters is equivalent to joining tags with the AND operator." (https://searchfox.org/firefox-main/source/testing/mozbase/manifestparser/manifestparser/filters.py#364).
