class PseudoCluster(ABC):
    """
    PseudoCluster is an abstract interface that custom pseudo clusters
    should inherit from.

    The interface expose a name property that is used while looking
    where to dispatch the test step to.

    The implementation should then expose methods where the name match
    the name used in the YAML test file.

    For example, the 'CustomCommands' pseudo cluster can be implemented as:

    class CustomCommand(PseudoCluster):
        name = 'CustomCommands'

        async def MyCustomMethod(self, request):
            pass

        async def MyCustomMethod(self, request):
            pass

    It can then be called from any test step as:

    - label: "Call a custom method"
      cluster: "CustomCommands"
      command: "MyCustomMethod"
      arguments:
          values:
              - name: "MyCustomParameter"
                value: "this_is_a_custom_value"
    """

    @abstractproperty
    def name(self):
        pass
