PTS

PTS creates GenieOps objects to learn which configurations have been applied to a device. The ops objects are snapshots of the operational state of devices in the topology. PTS executes multiple commands (via cli/yang/xml) to collection a feature’s state and operational information.

This concept may sound similar to a Verification, however, PTS is only executed in the common setup and the common cleanup; it does not run between Triggers. As PTS runs only twice, it allows Genie harness to take a complete snapshot of all the features configured on the device, without impacting the execution time.

Another advantage of PTS is the pts_golden_config feature. This feature allows Genie to verify that the operational state of the configuration applied to the device, precisely matches a previously created verified snapshot. This ensures the same operational state for every run with the same configuration. Users can find more information about pts_golden_config feature in the user guide.

Using Ops

Genie Ops objects are a snapshot of a particular Feature on a Device at a specific time. Hence Ops objects are suited perfectly to be used as a comparable PTS profile.

Now, let’s see how to create a PTS profile.

Step 0: Check if the Genie Ops class exists for the feature you want to run PTS on. If so, go to Step 2.

Step 1: Write a new Ops object or update an existing Ops object for the feature you would like to profile. Once this is done, commit the Ops object to Genie Ops.

Step 2: Add your PTS information to the pts_datafile as shown below:

<feature_name>:
    source:
        pkg: genie_libs.genie
        class: <your location, for example: ops.ospf.ospf.Ospf>
    exclude: [<list of generic keys to ignore in the comparison>]
    devices:
        uut:
            None

Note

More keys from the datafile schema can be added

Step 3: Ensure the job file is pointing to this file via the pts_datafile argument.

Step 4: To run PTS, execute your job via easypy with the required arguments.

Note

The only mandatory argument is the testbed file.
