-Testing your pipeline is a particularly important step in developing an effective data processing solution. The indirect nature of the Beam model, in which your user code constructs a pipeline graph to be executed remotely, can make debugging-failed runs a non-trivial task. Often it is faster and simpler to perform local unit testing on your pipeline code than to debug a pipeline's remote execution.

 Before running your pipeline on the runner of your choice, unit testing your pipeline code locally is often the best way to identify and fix bugs in your pipeline code. Unit testing your pipeline locally also allows you to use your familiar/favorite local debugging tools.
