```
public class JobLauncherTestUtils
extends java.lang.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 the current system time as a parameter. This will ensure restartability when no parameters are provided.

  - setJob
```
@Autowired
public void setJob(Job job)
```
    The Job instance that can be manipulated (e.g. launched) in this utility.
    参数:
    job - the AbstractJob to use
  - setJobRepository
```
@Autowired
public void setJobRepository(JobRepository jobRepository)
```
    The JobRepository to use for creating new JobExecution instances.
    参数:
    jobRepository - a JobRepository
  - getJobRepository
```
public JobRepository getJobRepository()
```
    返回:
    the job repository
  - getJob
```
public Job getJob()
```
    返回:
    the job
  - setJobLauncher
```
@Autowired
public void setJobLauncher(JobLauncher jobLauncher)
```
    A JobLauncher instance that can be used to launch jobs.
    参数:
    jobLauncher - a job launcher
  - getJobLauncher
```
public JobLauncher getJobLauncher()
```
    返回:
    the job launcher
  - launchJob
```
public JobExecution launchJob()
                       throws java.lang.Exception
```
    Launch the entire job, including all steps.
    返回:
    JobExecution, so that the test can validate the exit status
    抛出:
    java.lang.Exception - thrown if error occurs launching the job.
  - launchJob
```
public JobExecution launchJob(JobParameters jobParameters)
                       throws java.lang.Exception
```
    Launch the entire job, including all steps
    参数:
    jobParameters - instance of JobParameters.
    返回:
    JobExecution, so that the test can validate the exit status
    抛出:
    java.lang.Exception - thrown if error occurs launching the job.
  - getUniqueJobParameters
```
public JobParameters getUniqueJobParameters()
```
    返回:
    a new JobParameters object containing only a parameter for the current timestamp, to ensure that the job instance will be unique.
  - getStepRunner
```
protected StepRunner getStepRunner()
```
    Convenient method for subclasses to grab a StepRunner for running steps by name.
    返回:
    a StepRunner
  - launchStep
```
public JobExecution launchStep(java.lang.String stepName)
```
    Launch just the specified step in the job. A unique set of JobParameters will automatically be generated. An IllegalStateException is thrown if there is no Step with the given name.
    参数:
    stepName - The name of the step to launch
    返回:
    JobExecution
  - launchStep
```
public JobExecution launchStep(java.lang.String stepName,
                               ExecutionContext jobExecutionContext)
```
    Launch just the specified step in the job. A unique set of JobParameters will automatically be generated. An IllegalStateException is thrown if there is no Step with the given name.
    参数:
    stepName - The name of the step to launch
    jobExecutionContext - An ExecutionContext whose values will be loaded into the Job ExecutionContext prior to launching the step.
    返回:
    JobExecution
  - launchStep
```
public JobExecution launchStep(java.lang.String stepName,
                               JobParameters jobParameters)
```
    Launch just the specified step in the job. An IllegalStateException is thrown if there is no Step with the given name.
    参数:
    stepName - The name of the step to launch
    jobParameters - The JobParameters to use during the launch
    返回:
    JobExecution
  - launchStep
```
public JobExecution launchStep(java.lang.String stepName,
                               JobParameters jobParameters,

                               ExecutionContext jobExecutionContext)
```
    Launch just the specified step in the job. An IllegalStateException is thrown if there is no Step with the given name.
    参数:
    stepName - The name of the step to launch
