Iterate not iterating

[mihaigabi]

I am trying to get the junos snapshot version on an EX switch but I can't make the tool to display the correct "snapshot-medium". It is always the first in the XML. Am I doing it wrong? Thanks!

The configuration:

test-snapshot:
  - rpc: get-snapshot-information
  - args:
      media: internal
  - iterate:
      xpath: "//snapshot-information/software-version/package[normalize-space(package-name)= 'junos']"
      id: "../../snapshot-medium"
      tests:
        - contains: package-version, 14.1
          info: "Test Succeeded! The snapshot version for <{{post['package-name']}}> on medium <{{id_0}}> is <{{post['package-version']}}>!"
          err: "Test Failed! The snapshot version for <{{post['package-name']}}> on medium <{{id_0}}> is <{{post['package-version']}}>!"

The result:

*************************RPC is get-snapshot-information*************************
----------------------Performing contains Test Operation----------------------
Test Succeeded! The snapshot version for <junos> on medium <internal (/dev/da0s1a) (primary)> is <ex-14.1X53-D42.3>!
Test Succeeded! The snapshot version for <junos> on medium <internal (/dev/da0s1a) (primary)> is <ex-14.1X53-D35.3>!

@mihaigabi What is the output you are expecting?

[mihaigabi]

I would like to get the below output:

The snapshot version for on medium <internal (/dev/da0s1a) (primary)> is ! The snapshot version for on medium <internal (/dev/da0s2a) (backup)> is !

Thanks!

The snapshot-medium is not a part of software-version but a sibling to it. So with the above implementation, it will always take the first value of snapshot-medium as the id-value(ex - /dev/da0s1a in above dataset).

You may try with something like the below.

test:
   - rpc: get-snapshot-information
   - args:
      media: internal
   - iterate:
      xpath: "//snapshot-information/software-version/package[normalize-space(package-name)='junos']"
      id: "../preceding-sibling::snapshot-medium[1]"
      tests:
          - contains: package-version, 14.1
            info: "Test Succeeded! The snapshot version for <{{post['package-name']}}> on medium <{{id_0}}> is <{{post['package-version']}}>!"
            err: "Test Failed! The snapshot version for <{{post['package-name']}}> on medium <{{id_0}}> is <{{post['package-version']}}>!"

I tested it locally and gives the desired output as expected. This workaround should help.
