=== Enable Automation Test in Poky ===
Please see the [http://www.yoctoproject.org/docs/current/dev-manual/dev-manual.html#performing-automated-runtime-testing Performing Automated Runtime Testing] section of the Yocto Project Development Manual.
Currently we have implemented two automated sanity test cases in Poky. User can follow below steps to enable the automation test:
 
* Make sure your working tree has latest test code. The first sanity test implementation is checked in poky master tree as commit, '''fd1d661b391dfad1edaac937a17c1165f635031a.
* Make sure your machine has package "expect" installed. The package is necessary for testing. We will add a recipe for it later. Currently, you need install it by yourself. On Ubuntu host, you can use apt-get to install expect:
<pre>
$ apt-get install expect
</pre>
* Edit /etc/sudoers to allow the user run sudo without prompted for a password. For example, you can do like following for user "tester":
<pre>
$ cat /etc/sudoers
# /etc/sudoers
#
# This file MUST be edited with the 'visudo' command as root.
#
# See the man page for details on how to write a sudoers file.
#
....
....
....
 
%tester ALL=(ALL) NOPASSWD: NOPASSWD: ALL
</pre>
* Instead of requiring sudo access, you can run the poky-gen-tapdevs script from a build of meta-ide-support or a Poky toolchain install in /opt/poky. The script will create and set up networking for one or more tap devices that will be used automatically by the poky-qemu script if detected.
* Typically, you need a X environment to start QEMU. You can use your desktop's DISPLAY. Or, alternatively, you can install vncserver, and startup a X environment in localhost:x.0. (x can be 1, 2, 3.....n)
* For the VNC setup, the following xstartup script is known to work for an openSUSE 11.2 host:
<pre>
#!/bin/sh
 
xrdb $HOME/.Xresources
xsetroot -solid grey
xhost +
xterm -geometry 80x24+10+10 -ls -title "$VNCDESKTOP Desktop" &
twm &
</pre>
* For the VNC setup, you will also want to put the following in ~/.twmrc, which allows windows to be placed automatically.
<pre>
RandomPlacement
</pre>
* You need set "IMAGETEST" to "qemu" in build/conf/local.conf
<pre>
$ cat local.conf
.....
# Set IMAGETEST to qemu if you want to build testcases and start
# testing in qemu after do_rootfs.
IMAGETEST = "qemu"
.....
</pre>
* Then you can run "bitbake poky-image-xxx" (xxx can be minimal, sato, sdk). After the kernel/image are generated, you need run "bitbake poky-image-xxx -c qemuimagetest". It will trigger automation test and you will get the result after a while. :)
