Description

3 years ago
Today i have seen the following failure a lot of times in a Travis build. I can reproduce it locally when run under XVFB and e10s mode turned on:

Here the command for firefox-ui-tests:

DISPLAY=:99.0 && firefox-ui-functional --binary /mozilla/bin/nightly/firefox --e10s firefox_puppeteer/tests/ --pref "marionette.logging:True"

Here some line from a local log and Marionette debugging turned on:

1452892022269	Marionette	TRACE	conn89 -> [0,74,"getCurrentChromeWindowHandle",null]
1452892022269	Marionette	TRACE	conn89 <- [1,74,null,{"value":"3"}]

I’m unable to run the tests using the command you provided above:

Yesterday I merged the python_packages branch for bug 1232967 into mozilla-central. So the path to the puppeteer tests have been changed: https://github.com/mozilla/firefox-ui-tests/tree/mozilla-central/firefox_ui_tests/firefox_ui_tests/puppeteer
Flags: needinfo?(hskupin)
Thanks!

The command `firefox-ui-functional --binary /home/ato/1/gecko/build/desktop-release/dist/bin/firefox-bin --e10s firefox_ui_tests/firefox_ui_tests/puppeteer --pref "marionette.logging:True"` appears to work.
This is the same problem you will run into if you wrap your command using xvfb-run.  The explanation is that certain parts of the Firefox UI needs a window manager in order to function normally.

If you imagine wrapping your command in a naïve xvfb wrapper that includes a window manager such as this:

    #!/bin/sh
    DISPLAY=:99
    Xvfb $DISPLAY -ac +extension RANDR &
    matchbox-window-manager &
    exec $@

All the tests will pass:

    % chmod +x xvfb-wm-run
    % ./xvfb-wm-run firefox-ui-functional --binary /home/ato/Code/gecko/build/desktop-release/dist/bin/firefox-bin firefox_ui_tests/firefox_ui_tests/puppeteer/test_toolbars.py --pref "marionette.logging:True"

    …

    SUMMARY
    -------
    passed: 13
    failed: 0
    todo: 0

It is possible that replacing matchbox-window-manager with xinit will work if you have that installed.
