Class StepRunner

java.lang.Object
  extended by org.springframework.batch.test.StepRunner

public class StepRunner
extends Object

Utility class for executing steps outside of a Job. This is useful in end to end testing in order to allow for the testing of a step individually without running every Step in a job.

It should be noted that any checked exceptions encountered while running the Step will wrapped with RuntimeException. Any checked exception thrown will be due to a framework error, not the logic of the step, and thus requiring a throws declaration in clients of this class is unnecessary.
