1836373 - Risk of messages in tree causing failures of random automated tests

Status: NEW

(Firefox :: Messaging System, defect, P3)

Description

[Shane Hughes [:aminomancer]]

Messaging is generally enabled during tests since it's enabled by default. This doesn't usually cause too many problems since most of our messages trigger in very specific conditions so they don't come up during automated tests. But in some cases, messages that work fine in experiments will cause problems when landing in tree (see bug 1831144 for example - the message unexpectedly appears on startup when other tests, unrelated to FxMS, are running).

There might be an easy way to disable this specific message during automated tests by just changing its targeting. Then, our own tests can enable it so they can test on it, but the rest of Firefox's browser tests don't need to be edited to account for it. But since this isn't really a problem with this specific message, but a universal risk for all messages with lenient enough trigger/targeting, we should consider a more universal approach to fixing this. For example, disable ASRouter entirely when a pref is set, and set that pref in some file that runs as part of the test harness, or something.
