927476 - Robocop pixel tests fail consistently on Android x86 emulator and many devices

Status: RESOLVED FIXED

Description

[Geoff Brown [:gbrown]]

+++ This bug was initially created as a clone of Bug #898036 +++

The Robocop pixel tests -- testLoad, testAxisLocking, etc -- fail consistently when run on the x86 emulator. They also fail locally when run on a Motorola Razr i (XT890) or Galaxy S.

Running locally, the screen looks the same as it did in bug 898036 before we added pref layout.css.devPixelsPerPx="1.0".

It looks to me like that pref is still defined. I wonder if this might have been regressed by bug 912166.

It appears this was not regressed by bug 912166.

Debugging suggests that the test harness is setting the pref, but not setting it correctly.

Comment 2

[Geoff Brown [:gbrown]]

Bug 746243 updated the way extra preferences are handled. As a side-effect, the quoting that was previously needed for this pref is no longer necessary, so the pref value is set to "1.0" instead of 1.0.

If I remove the extra quotes for devPixelsPerPx, pixel tests pass and the prefs passed to mozprofile are:

This one still doesn't look right:

u'robocop.logfile': u'"/mnt/sdcard/tests/robocop.log"', 

I'll look into that too.

Attachment: Remove extra pref quoting

Pref robocop.logfile is never used (we write "logfile=..." into robotium.config instead) -- so I removed that pref completely.
