Test definitions

The test definition is a yaml file that describe the tests that you want LAVA to run on the DUT.

Smoke example

Let's look at this example:

metadata:
  format: Lava-Test Test Definition 1.0
  name: smoke-tests-basic
  description: "Run basic smoke tests."

run:
  steps:
  - lava-test-case linux-posix-pwd --shell pwd
  - lava-test-case linux-posix-uname --shell uname -a
  - lava-test-case linux-posix-vmstat --shell vmstat
  - lava-test-case linux-posix-ifconfig --shell ifconfig -a
  - lava-test-case linux-posix-lscpu --shell lscpu
  - lava-test-case linux-posix-lsb_release --shell lsb_release -a

Metadata

The metadata dictionary describes the test. format and name are mandatory while description is optional.

Run

The dictionary list the actions that LAVA should execute on the DUT. The only available key is steps.

steps is an array that will be transformed into a shell script that LAVA will run on the DUT.

In this example, run.steps will be rendered into the following shell script:

###default parameters from test definition###
######
###test parameters from job submission###
######
set -e
set -x
export TESTRUN_ID=0_smoke-tests-basic
cd /lava-4212/0/tests/0_smoke-tests-basic
UUID=`cat uuid`
set +x
echo "<LAVA_SIGNAL_STARTRUN $TESTRUN_ID $UUID>"
set -x
lava-test-case linux-posix-pwd --shell pwd
lava-test-case linux-posix-uname --shell uname -a
lava-test-case linux-posix-vmstat --shell vmstat
lava-test-case linux-posix-ifconfig --shell ifconfig -a
lava-test-case linux-posix-lscpu --shell lscpu
lava-test-case linux-posix-lsb_release --shell lsb_release -a
set +x
echo "<LAVA_SIGNAL_ENDRUN $TESTRUN_ID $UUID>"

Install

install

LAVA can also install some packages or sources before running the tests. See the technical documentation for more information.
