Class JobLauncherTestUtils

java.lang.Object
org.springframework.batch.test.JobLauncherTestUtils
public class JobLauncherTestUtils extends Object

Utility class for testing batch jobs. It provides methods for launching an entire AbstractJob, allowing for end to end testing of individual steps, without having to run every step in the job. Any test classes using this utility can set up an instance in the ApplicationContext as part of the Spring test framework.

This class also provides the ability to run Steps from a FlowJob or SimpleJob individually. By launching Steps within a Job on their own, end to end testing of individual steps can be performed without having to run every step in the job.

It should be noted that using any of the methods that don't contain JobParameters in their signature, will result in one being created with a random number of type long as a parameter. This will ensure restartability when no parameters are provided.

      Returns:
      the job launcher

    • launchJob

      public JobExecution launchJob() throws Exception
      Launch the entire job, including all steps.
      Returns:
      JobExecution, so that the test can validate the exit status
      Throws:

      Exception - thrown if error occurs launching the job.

    • getUniqueJobParameters

      public JobParameters getUniqueJobParameters()
      Returns:
      a new JobParameters object containing only a parameter with a random number of type long, to ensure that the job instance will be unique.

    • getUniqueJobParametersBuilder

      public JobParametersBuilder getUniqueJobParametersBuilder()
      Returns:
      a new JobParametersBuilder object containing only a parameter with a random number of type long, to ensure that the job instance will be unique.
