Job definition¶

The job definition is a yaml file that you submit to the LAVA server. This file is describing everything that LAVA needs to know to run your tests on a DUT.

QEMU example¶

Let's look at this example:

device_type: qemu
job_name: simple qemu job

timeouts:
  job:
    minutes: 20
priority: medium
visibility: public

context:
  arch: amd64

actions:
- deploy:
    to: tmpfs
    timeout:
      minutes: 20
    images:
      rootfs:
        url: http://images.validation.linaro.org/kvm/debian-sid-2014_08_21-amd64.qcow2.xz
        image_arg: -drive format=qcow2,file={rootfs}
        format: qcow2
        compression: xz
    os: debian

- boot:
    method: qemu
    media: tmpfs
    timeout:
      minutes: 5
    prompts:
    - 'root@debian:~#'
    auto_login:
      login_prompt: "login:"
      username: root

- test:
    timeout:
      minutes: 5
    definitions:
    - repository: https://github.com/Linaro/test-definitions
      from: git
      path: automated/linux/smoke/smoke.yaml
      name: smoke-tests
    - repository: https://github.com/Linaro/test-definitions
      from: git
      path: automated/linux/meminfo/meminfo.yaml
      name: meminfo

Structure¶

The job definition is made of:

device_type: requested device-type
job_name: name of the job, sometime called description
timeouts: timeout definition
priority: job priority
visibility: job visibility
actions: list of actions to run

In this definition, we request to run a job called simple qemu tjob on a qemu DUT. The job is visible to everyone (including anonymous users). The job will not run for more than 10 minutes at medium priority.

Actions¶

actions is a list of actions that LAVA will have to execute for the given job.

Currently, LAVA support four type of actions:

command: run commands on the dispatcher
deploy: deploy software on the DUT
boot: boot the DUT
test: run some tests

Deploy¶

The deploy action will deploy the software on the DUT, using the method specified by the to.

In this example, we are requesting to deploy to tmpfs. The rootfs will be downloaded from the given url.

deployment methods

LAVA supports many deployment methods. However, only some methods are supported by each device-type.

Boot¶

The boot action will boot the DUT, using the method specified by the method.

In this example, we are requesting to boot qemu using the software from tmpfs.

boot methods

LAVA supports many boot methods. However, only some methods are supported by each device-type.

Test¶

The test action will run the given tests on the DUT.

In this example, LAVA will download the test definitions from two git repositories.

test methods

LAVA supports three test methods that do not depend on the device-type.
