A Data Set is a static pre-defined collection of rows, used in [unit testing^](/data-shaper-1.21/knowing-the-data-shaper-designer/index-2/pipeline-unit-test.md), where a data set is used as an alternative input data set. This input set is used to be processed in a unit testing pipeline. After processing the result of the pipeline is compared to a data set that has been specified as the 'golden data set' for the test.
