Unit tests for properties that can be set to null

[andy-maier]

Make sure that properties that can be set to null at the zhmcclient API have corresponding unit tests.

As of z14 (2.14.0) and for the currently supported HMC operations in the zhmcclient (2.16.1.dev18 + PR #398), the following properties (or sub-fields thereof) can be set to null.

Unless otherwise stated, the property is set to null using the "Update Properties" operation.

  • partition-id
  • boot-network-device
  • boot-ftp-host
  • boot-ftp-username
  • boot-ftp-password
  • boot-ftp-insfile
  • boot-removable-media
  • boot-removable-media-type
  • boot-storage-device
  • boot-logical-unit-number
  • boot-world-wide-port-name
  • boot-iso-image-name
  • boot-iso-ins-file
  • crypto-configuration (read-only, set to null via "Decrease Crypto Adapter Configuration" operation)
  • ssc-ipv4-gateway
  • ssc-ipv6-gateway
  • ssc-master-userid
