1499522 - Thunderbird Xpcshell testing: toolkit/components/telemetry/tests/unit/test_TelemetrySession.js fails

Status: RESOLVED DUPLICATE of bug 1499361

(Thunderbird :: Testing Infrastructure, enhancement)

Description

[Jorg K (CEST = GMT+2)]

test_TelemetrySession.js has caused many failures when run with Thunderbird in the past.

Since today we get this perma-red failure on all platforms:
TEST-UNEXPECTED-FAIL | toolkit/components/telemetry/tests/unit/test_TelemetrySession.js | test_environmentChange - [test_environmentChange : 962] "undefined" deepEqual {"browserIsUserDefault":true,"newTabPageEnabled":true,"pdfViewerUsed":false}

That makes sheriffing a little hard.

M-C last good: 4c11ab0cd98950983cfc957f579ace6c3e
M-C first bad: 3c8790a73b7f31b253704a07e1bf7d0a65

Looks like it's from here:

Robert and Jan-Erik, how can we fix this for TB?

Robert just landed a patch skipping that part of the test if the `prio.enabled` pref is not set (or false): bug 1499361.
That should solve it for Thunderbird as well I think?

Thanks, I'll follow the other bug.
