无头硒/量角器不向 Firefox 发送输出

Question

我正在使用：

火狐30
selenium-server-standalone-2.43.1.jar
Xvfb
Ubuntu 无头
Lineman grunt spec-e2e

我能够毫无错误地运行 Xvfb、Firefox 和 lineman grunt spec-e2e。

我在所有终端上运行export DISPLAY=:10

我在一个终端上运行 Xvfb :10 -ac 没有任何问题，我明白了：

Initializing built-in extension Generic Event Extension
Initializing built-in extension SHAPE
Initializing built-in extension MIT-SHM
Initializing built-in extension XInputExtension
Initializing built-in extension XTEST

Initializing built-in extension XVideo-MotionCompensation
Initializing built-in extension SELinux
Initializing built-in extension GLX
[dix] Could not init font path element /usr/share/fonts/X11/cyrillic, removing from list!

在单独的终端上，我运行 Firefox：

one@node ~/github/load-balancer-service/app/js/loadbalancer/controllers $ firefox

(process:16020): GLib-CRITICAL **: g_slice_set_config: assertion 'sys_page_size == 0' failed
Xlib:  extension "RANDR" missing on display ":10".

最后，我在 lineman 中运行（还有一个额外的 lineman run 会话）：

one@node ~/github/load-balancer-service $ lineman grunt spec-e2e
Running "spec-e2e" task
Starting selenium standalone server...
Selenium standalone server started at http://10.14.13.161:42182/wd/hub
one@node ~/github/load-balancer-service $

但我遇到的问题是运行 Firefox 的终端窗口没有输出。当我运行 spec-e2e 时，我确实看到 Xvfb 终端窗口有以下输出：

但我没有看到 spec-e2e 的输出进入 firefox 窗口。

必须使用selenium/selenium-server-standalone-2.42.2.jar 而不是其他版本。
