LAVA TEST DEFINITIONS


A LAVA Test Definition comprises of two parts:

· the data to setup the test, expressed as a JSON file.

· the instructions to run inside the test, expressed as a YAML file.

This allows the same tests to be easily migrated to a range of different devices,
environments and purposes by using the same YAML files in multiple JSON files. It also
allows tests to be built from a range of components by aggregating YAML files inside a
single JSON file.

CONTENTS OF THE JSON FILE


The JSON file is submitted to the LAVA server and contains:

· Demarcation as a health check or a user test.

· The default timeout of each action within the test.

· The logging level for the test, DEBUG or INFO.

· The name of the test, shown in the list of jobs.

· The location of all support files.

· All parameters necessary to use the support files.

· The declaration of which device(s) to use for the test.

· The location to which the results should be uploaded.

· The JSON determines how the test is deployed onto the device and where to find the tests
to be run.

BASIC JSON FILE


Your first LAVA test should use the DEBUG logging level so that it is easier to see what
is happening.

A suitable timeout for your first tests is 900 seconds.

Make the job_name descriptive and explanatory, you will want to be able to tell which job
is which when reviewing the results.

Make sure the device_type matches exactly with one of the suitable device types listed on
the server to which you want to submit this job.

Change the stream to one to which you are allowed to upload results, on your chosen
server.
