如何在jUnit中编辑作业的执行上下文

Question

我能够从joblaunchertestutils启动作业并传递作业参数。我也想通过executioncontext考试。像这样的东西，但它不起作用

@MockBean
JobExecution jobExecution;

@MockBean
ExecutionContext executionContext ;

@MockBean
DownloadDecider downloadDecider;

@MockBean
StepExecution stepExecution;

@BeforeAll
public void setUp() throws Exception {
    
    when(jobExecution.getExecutionContext()).thenReturn(this.executionContext);
    when(jobExecution.getExecutionContext().get(BatchRESULTS)).thenReturn("src/test/r");

@Test public void testJob（）引发异常{

    JobParameters params1 = new JobParameters(setJobParams());
    jobLauncherTestUtils.setJobLauncher(jobLauncher);
    
    
}

@组件（“DownloadDecider”）公共类DownloadDecider实现JobExecutionDecider{

Logger logger = LoggerFactory.getLogger(DownloadDecider.class);

@Override
public FlowExecutionStatus decide(JobExecution jobExecution, StepExecution stepExecution) {
    
    System.out.println(stepExecution.getExitStatus().getExitCode());
    System.out.println(jobExecution.getExecutionContext().get(BatchRESULTS));

//打印空。未传递该值

Answer 1

此处的模拟设置不正确：

when(jobExecution.getExecutionContext()).thenReturn(this.executionContext);
when(jobExecution.getExecutionContext().get(BatchRESULTS)).thenReturn("src/test/r");

您需要首先从执行上下文中模拟所需的行为，然后在作业执行中进行设置：

when(this.executionContext.get(BatchRESULTS)).thenReturn("src/test/r");
when(jobExecution.getExecutionContext()).thenReturn(this.executionContext);
