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.

inOnlyPane

PAssert.IterableAssert<T> inOnlyPane(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 expect outputs to be produced to the provided window exactly once. If the upstream Trigger may produce output multiple times, consider instead using 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.

inEarlyPane

PAssert.IterableAssert<T> inEarlyPane(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 produced by the arrival of early data.

Returns:

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

inLatePane

PAssert.IterableAssert<T> inLatePane(BoundedWindow window)

Creates a new PAssert.IterableAssert with the assertion restricted to only run on the provided window across all panes that were 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.

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)
