v811_spc009/development/tools/labpretest

Overview:

The labpretest.sh script is designed to emulate a typical automated test lab
session.  It puts a device into bootloader mode, reboots into bootloader mode,
determines device type, erases user cache, flashes a generic userdata image,
updates the bootloader image, updates the radio image, updates the system image
and reboots, sets up for a monkey run and finally runs a random monkey test.
It will repeat this based on an optional parameter(-i) or default to 100 times.
It will detect if it is in a low battery situation and wait for it to charge
again.

The goal is to see if a device is ready for deployment to automated lab testing
and can also be used to verify that lab infrastructure is ready for devices.
The idea is to run this script at the same time for multiple devices, typically
I would connect 8 devices to a host and run this script in 8 separate shell
sessions and watch for failures.

Running the script:

If there is only one device attached to the host you can simply just run the
script, it will detect the device and go through 100 cycles, running the monkey
for 200 events each cycle.  The script ignores normal monkey failures. If you
have multiple devices attached use the -d <device_id> parameter to target a
specific devices.  Additional parameters are -i for how many cycles and -m for
how many monkey events and finally -x to make it skip the monkey run portion
altogether.

Adding support for new devices or from scratch:

The script uses included copies of adb and fastboot which are in in the tools/
sub directory. If you are setting this up with only the script, create a tools
sub directory and put adb and fastboot in it and make sure they are executable.
Currently we use userdebug builds.

Here are the steps to add a new device:

  1) Create a new sub directory using the result of "fastboot getvar product".
  2) Copy a build image to the new sub directory in our format.
     (i.e. passion-img-24827.zip)
  3) Copy a boot image to the new sub directory in our format.
     (i.e. hboot.0.33.2012.img)
  4) Copy a radio image to the new sub directory in our format.
     (i.e. radio.4.04.00.03_2.img)
  5) Copy a userdata.img file, possibly from one of the other directories.

Customizations to the flashing process are handled by adding a custom_flash.sh
file that is read in before the main loop starts. It allows you to add any non
generic functions or details to the flashing process. You must use it to define
the variable "bootpart" which is not defined by default. Also, use this file to
rewrite the flash_device function and any others, etc...

The script should handle the rest, unless there are radical changes to file
names or the process.
