public static interface PAssert.IterableAssert<T>

Builder interface for assertions applicable to iterables and PCollection contents.

Method Summary

Modifier and Type	Method and Description
PAssert.IterableAssert<T>	containsInAnyOrder(java.lang.Iterable<T> expectedElements) Asserts that the iterable in question contains the provided elements.
PAssert.IterableAssert<T>	containsInAnyOrder(T... expectedElements) Asserts that the iterable in question contains the provided elements.
PAssert.IterableAssert<T>	empty() Asserts that the iterable in question is empty.
PAssert.IterableAssert<T>	inCombinedNonLatePanes(BoundedWindow window) Creates a new PAssert.IterableAssert like this one, but with the assertion restricted to only run on the provided window across all panes that were not produced by the arrival of late data.
PAssert.IterableAssert<T>	inEarlyGlobalWindowPanes() Creates a new PAssert.IterableAssert like this one, but with the assertion restricted to only run on panes in the GlobalWindow that were emitted before the GlobalWindow closed.
PAssert.IterableAssert<T>	inFinalPane(BoundedWindow window) Creates a new PAssert.IterableAssert like this one, but with the assertion restricted to only run on the provided window, running the checker only on the final pane for each key.
PAssert.IterableAssert<T>	inOnTimePane(BoundedWindow window) Creates a new PAssert.IterableAssert like this one, but with the assertion restricted to only run on the provided window.
PAssert.IterableAssert<T>	inWindow(BoundedWindow window) Creates a new PAssert.IterableAssert like this one, but with the assertion restricted to only run on the provided window.
PAssert.IterableAssert<T>	satisfies(SerializableFunction<java.lang.Iterable<T>,java.lang.Void> checkerFn) Applies the provided checking function (presumably containing assertions) to the iterable in question.

Method Detail

inWindow

PAssert.IterableAssert<T> inWindow(BoundedWindow window)

Creates a new PAssert.IterableAssert like this one, but with the assertion restricted to only run on the provided window.

The assertion will concatenate all panes present in the provided window if the Trigger produces multiple panes. If the windowing strategy accumulates fired panes and triggers fire multple times, consider using instead inFinalPane(BoundedWindow) or inOnTimePane(BoundedWindow).

Returns:

a new PAssert.IterableAssert like this one but with the assertion only applied to the specified window.

inFinalPane

PAssert.IterableAssert<T> inFinalPane(BoundedWindow window)

Creates a new PAssert.IterableAssert like this one, but with the assertion restricted to only run on the provided window, running the checker only on the final pane for each key.

If the input WindowingStrategy does not always produce final panes, the assertion may be executed over an empty input even if the trigger has fired previously. To ensure that a final pane is always produced, set the Window.ClosingBehavior of the windowing strategy (via Window.withAllowedLateness(Duration, ClosingBehavior) setting Window.ClosingBehavior to Window.ClosingBehavior.FIRE_ALWAYS).

Returns:

a new PAssert.IterableAssert like this one but with the assertion only applied to the specified window.

inOnTimePane

PAssert.IterableAssert<T> inOnTimePane(BoundedWindow window)

Creates a new PAssert.IterableAssert like this one, but with the assertion restricted to only run on the provided window.

Returns:

a new PAssert.IterableAssert like this one but with the assertion only applied to the specified window.

inCombinedNonLatePanes

PAssert.IterableAssert<T> inCombinedNonLatePanes(BoundedWindow window)

Creates a new PAssert.IterableAssert like this one, but with the assertion restricted to only run on the provided window across all panes that were not produced by the arrival of late data.

Returns:

a new PAssert.IterableAssert like this one but with the assertion only applied to the specified window.

inEarlyGlobalWindowPanes

PAssert.IterableAssert<T> inEarlyGlobalWindowPanes()

Creates a new PAssert.IterableAssert like this one, but with the assertion restricted to only run on panes in the GlobalWindow that were emitted before the GlobalWindow closed. These panes have PaneInfo.Timing.EARLY.

containsInAnyOrder

PAssert.IterableAssert<T> containsInAnyOrder(T... expectedElements)

Asserts that the iterable in question contains the provided elements.

Returns:

the same PAssert.IterableAssert builder for further assertions

containsInAnyOrder

PAssert.IterableAssert<T> containsInAnyOrder(java.lang.Iterable<T> expectedElements)

Asserts that the iterable in question contains the provided elements.

Returns:

the same PAssert.IterableAssert builder for further assertions

empty

PAssert.IterableAssert<T> empty()

Asserts that the iterable in question is empty.

Returns:

the same PAssert.IterableAssert builder for further assertions

satisfies

PAssert.IterableAssert<T> satisfies(SerializableFunction<java.lang.Iterable<T>,java.lang.Void> checkerFn)

Applies the provided checking function (presumably containing assertions) to the iterable in question.

Returns:

the same PAssert.IterableAssert builder for further assertions
