Package akka.stream.testkit

Class TestSourceStage<T,M>

java.lang.Object

akka.stream.stage.GraphStageWithMaterializedValue<SourceShape<T>,M>

akka.stream.testkit.TestSourceStage<T,M>

All Implemented Interfaces:

Graph<SourceShape<T>,M>

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.
