The purpose of this module is to deploy a test image on a EFI-enabled hardware
and run our runtime tests. A bit of background:
- testimage.bbclass uses the concept of TEST_TARGET which is a class name
that is responsible for target deploying. A layer can provide
it's own TEST_TARGET. Right now has OE-core has a QemuTarget and a SimpleRemoteTarget
(ssh into an already up and running machine and run tests), the default one being qemu.
- basically testimage does something like:
target.deploy()
try:
target.start()
runTests()
finally:
target.stop()
This module assumes a running EFI machine with gummiboot as bootloader and
core-image-testmaster installed (or similar). Also your hardware under test has
to be in a DHCP-enabled network that gives it the same IP for each reboot.
One time setup (master image):
- build core-image-testmaster with EFI_PROVIDER = "gummiboot"
- install the image on the target
Test image setup:
- build your test image, e.g core-image-sato as you usually do, but with these in local.conf:
IMAGE_FSTYPES += "tar.gz"
- Now run the tests:
INHERIT += "testimage"
TEST_TARGET = "GummibootTarget"
TEST_TARGET_IP = "192.168.2.3"
bitbake core-image-sato -c testimage
Other notes:
- TEST_POWERCONTROL_CMD (togheter with TEST_POWERCONTROL_EXTRA_ARGS) can be a command that runs on the host and does power cycling.
The test code passes one argument to that command: off, on or cycle (off then on). In my case I use something like
TEST_POWERCONTROL_CMD="powercontrol.exp test 10.11.12.1 nuc1" in local.conf.
Basically my expect script does: 'ssh test@10.11.12.1 "pyctl nuc1 <arg>" and runs a python script there that controls power for a label called nuc1'.
The reason why my expect script has to ssh into another machine is because of network topology, and that machine is the one actually connected
to the test rack and the power strip. That's why TEST_POWERCONTROL_CMD and _ARGS need to be customized for one's setup, the only requirement being
that it accepts: on/off/cycle as the last argument.
- if no command is defined it would use classic reboot. This is fine as long as the machine
actually reboots (as in the ssh test hasn't failed), but it's useful for "simple-setup-with-one-board-on-the-desk" scenario, where
some manual interaction is okay from time to time.

README
Poky
====
Poky is an integration of various components to form a complete prepackaged
build system and development environment. It features support for building
customised embedded device style images. There are reference demo images
featuring a X11/Matchbox/GTK themed UI called Sato. The system supports
cross-architecture application development using QEMU emulation and a
standalone toolchain and SDK with IDE integration.
Additional information on the specifics of hardware that Poky supports
is available in README.hardware. Further hardware support can easily be added
in the form of layers which extend the systems capabilities in a modular way.
As an integration layer Poky consists of several upstream projects such as
BitBake, OpenEmbedded-Core, Yocto documentation and various sources of information
e.g. for the hardware support. Poky is in turn a component of the Yocto Project.
The Yocto Project has extensive documentation about the system including a
reference manual which can be found at:
http://yoctoproject.org/documentation
OpenEmbedded-Core is a layer containing the core metadata for current versions
of OpenEmbedded. It is distro-less (can build a functional image with
DISTRO = "nodistro") and contains only emulated machine support.
For information about OpenEmbedded, see the OpenEmbedded website:
http://www.openembedded.org/
Where to Send Patches
=====================
As Poky is an integration repository, patches against the various components
should be sent to their respective upstreams.
bitbake:
bitbake-devel@lists.openembedded.org
meta-yocto:
poky@yoctoproject.org
Most everything else should be sent to the OpenEmbedded Core mailing list. If
in doubt, check the oe-core git repository for the content you intend to modify.
Before sending, be sure the patches apply cleanly to the current oe-core git
repository.
openembedded-core@lists.openembedded.org
Note: The scripts directory should be treated with extra care as it is a mix
of oe-core and poky-specific files.
