Most Spark users spin up clusters with sample data sets to develop code — this is slow (clusters are slow to start) and costly (you need to pay for computing resources).. An automated test suite lets you develop code on your local machine free of charge. As a result, here are links to the 12 ScalaTest tutorials in that chapter: As mentioned, these tips and tutorials come from the Scala Cookbook.
