All Methods Static Methods Instance Methods Concrete Methods
Modifier and Type	Method	Description
`static <T,M> Source<T,M>`	`apply(GraphStageWithMaterializedValue<SourceShape<T>,M> stageUnderTest, TestProbe probe)`	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`.
`scala.Tuple2<GraphStageLogic,M>`	`createLogicAndMaterializedValue(Attributes inheritedAttributes)`
`Outlet<T>`	`out()`
`SourceShape<T>`	`shape()`	The shape of a graph is all that is externally visible: its inlets and outlets.

- Method Detail
  - apply
```
public static <T,M> Source<T,M> apply(GraphStageWithMaterializedValue<SourceShape<T>,M> stageUnderTest,
                                                  TestProbe probe)
```
    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.
