Class TestSourceStage<T,​M>

  • All Implemented Interfaces:

    public class TestSourceStage<T,​M>
    extends GraphStageWithMaterializedValue<SourceShape<T>,​M>
    Creates a source out of the stageUnderTest that will inform the probe of operator events and callbacks by sending it the various messages found under GraphStageMessages.

    This allows for creation of a "normal" stream starting with the source while still being able to assert internal events.
