On desktop, we need a way to set a pref that will allow us to store certified apps in a different place than the profile, so that we can simulate profile updates in integration tests. See Bug 1001680 Comment #2 for more info.

This will most likely be by setting a debug pref to let the system know that we are trying to run upgrade tests.

Talked to fabrice about this on IRC. Going to set up a pref (b2g.apps.desktop_coreappsdir) to point to where core apps are built. Will need to change this in the B2G directory provider, as well as the gaia build system, and make sure they sync up. After this, we should be able to provide a location to build the apps into, then redistribute profiles as necessary for testing. Also talked about having a command line argument for core app location, which the more I think about it, could be useful as an override for this without having to go in and edit prefs. Worth doing both maybe?

Comment on attachment 8576329 [details] [gaia] qdot:1001757-move-core-apps > mozilla-b2g:master Sorry I don't totally understand here =( If you want to modify PROFILE_DIR, you could do PROFILE_DIR?=$(GAIA_DIR)$(SEP)$(PROFILE_FOLDER)

Comment on attachment 8576329 [details] [gaia] qdot:1001757-move-core-apps > mozilla-b2g:master Ok. I fixed the ?= and the github comment. The reason I needed to move PROFILE_DIR up to its own variable instead of just having it in config is because before this patch, we assumed that the webapps dir that gaia builds would be in PROFILE_DIR. After this patch, we can now relocate the webapps dir wherever we want, mostly for upgrade testing purposes. We'll need to keep PROFILE_DIR the same (because we still want the profile in $GAIA_DIR/profile), and for most cases, we'll want to keep webapps in PROFILE_DIR too.

Comment on attachment 8576329 [details] [gaia] qdot:1001757-move-core-apps > mozilla-b2g:master OK, it seems fine to me. Could you tell me more detail steps of how do you simulate profile updates in integration tests? Thanks
