832499 - browser-chrome mochitests sometimes (?) redirect loads to unexpected pages

Status: RESOLVED WONTFIX

(Testing :: Mochitest, defect)

Description

[Nathan Froyd [:froydnj]]

I built mozilla-central from a clean tree and ran:

TEST_PATH=browser/base/content/test/browser_save_link-perwindowpb.js make mochitest-browser-chrome

from inside my build directory, no packaging steps or anything.  This test opens a new window and then navigates to a given page as its first steps.

Except that for some reason, new tabs are being opened pointed to:

http://www.mozilla.org/projects/firefox/21.0a1/firstrun/

which, as you might expect, causes problems.

I don't understand why this is.  I've checked that the appropriate preference files are being read and e.g. browser.startup.page is set correctly (to 0) in the pref files.  But inspecting values with about:config, browser.startup.page is 1.  Setting startup.homepage_override_url and startup.homepage_welcome_url to about:blank in automation.py.in appears to DTRT, but AFAICS such steps shouldn't be necessary.

It may be worth looking at the differences between running a single test versus multiple ones.

That's interesting.  Why would that make a difference?

I don't know, but I don't think I see this problem when running multiple tests. I might be misremembering, however.
