Testing

NPipeline ships a dedicated testing extension with in-memory nodes, a pipeline test harness, and assertion libraries for both AwesomeAssertions and FluentAssertions.

dotnet add package NPipeline.Extensions.Testing
dotnet add package NPipeline.Extensions.Testing.AwesomeAssertions  # or FluentAssertions

Unit test individual nodes by calling TransformAsync directly. Integration test full pipelines using PipelineTestHarness<T>, which runs the pipeline, captures results, and provides assertion helpers.
