      Examples that show how to use DeviceTestContext will make it easier for developers to use it for testing.

      Support for forwarded attributes enables better test coverage because SKA Control System Guidelines asks for forwarded attributes to be used in some TANGO devices.

      The tango-example project includes:

      • example of devices in a hierarchy using only DeviceTestContext - no device servers required to be run externally,
      • example using events, based on DeviceTestContext.

      Documentation updates:

      • Update (PR merged) official PyTango docs with notes from Testing in TANGO Controls confluence page.
      • Update (PR merged) official general TANGO docs with a link to this new PyTango page.
      • Add a link to the new PyTango docs on SKA developer portal. 

      Spike to investigate support for forwarded attributes in DeviceTestContext (and thus TANGO file-based database) has been completed:

      • If it can be fixed in PyTango, then a PR with fix must be merged (new release of PyTango outside the scope of this ticket).
      • If changes are required in cppTango, then at least an issue has been created on Github.

    Description

      Address current issues with DeviceTestContext:

      • Add example of a hierarchy of devices using just DeviceTestContext instances.
      • Add example using DeviceTestContext with events.
      • Investigate adding support for forwarded TANGO attributes.
      • Not an issue, but update official TANGO developer docs with notes on DeviceTestContext from SAR-29.

      These issues were identified as future work in Testing in TANGO Controls.
