Interface Summary

Interface	Description
NeedsRunner	Category tag for validation tests which utilize TestPipeline for execution and expect to be executed by a PipelineRunner.
PAssert.IterableAssert<T>	Builder interface for assertions applicable to iterables and PCollection contents.
PAssert.SingletonAssert<T>	Builder interface for assertions applicable to a single value.
RunnableOnService	Category tag for validation tests which utilize TestPipeline for execution and PAssert for validation.
SerializableMatcher<T>	A Matcher that is also Serializable.
TestPipelineOptions	TestPipelineOptions is a set of options for test pipelines.

Class Summary

Class	Description
CoderProperties	Properties for use in Coder tests.
CrashingRunner	A PipelineRunner that applies no overrides and throws an exception on calls to Pipeline.run().
PAssert	An assertion on the contents of a PCollection incorporated into the pipeline.
PAssert.GroupThenAssert<T>	A transform that applies an assertion-checking function over iterables of ActualT to the entirety of the contents of its input.
PAssert.GroupThenAssertForSingleton<T>	A transform that applies an assertion-checking function to a single iterable contained as the sole element of a PCollection.
PAssert.OneSideInputAssert<ActualT>	An assertion checker that takes a single PCollectionView<ActualT> and an assertion over ActualT, and checks it within a Beam pipeline.
SourceTestUtils	Helper functions and test harnesses for checking correctness of Source implementations.
TestPipeline	A creator of test pipelines that can be used inside of tests that can be configured to run locally or against a remote pipeline runner.
TestPipelineOptions.AlwaysPassMatcher	Matcher which will always pass.
TestPipelineOptions.AlwaysPassMatcherFactory	Factory for PipelineResult matchers which always pass.
WindowFnTestUtils	A utility class for testing WindowFns.

Enum Summary

Enum	Description
SourceTestUtils.ExpectedSplitOutcome	Expected outcome of BoundedSource.BoundedReader.splitAtFraction(double).

Package org.apache.beam.sdk.testing Description

Defines utilities for unit testing Dataflow pipelines. The tests for the PTransforms and examples included the Dataflow SDK provide examples of using these utilities.
