Question

我正在尝试测试Spring Batch步骤。我有2个场景要测试 1.使用tasklet步骤（步骤范围） 2.使用ItemReader / ItemWriter（步骤范围）步骤

我的测试类注释如下

@RunWith(SpringJUnit4ClassRunner.class)
@TestExecutionListeners({DependencyInjectionTestExecutionListener.class, StepScopeTestExecutionListener.class})
@ContextConfiguration(loader = SpringApplicationContextLoader.class, classes = ItemReturnsApplication.class)

This is how my test class looks like

@Bean
    JobLauncherTestUtils jobLauncherTestUtils(){
        return new JobLauncherTestUtils();
    }

    @Autowired
    private JobLauncherTestUtils jobLauncherTestUtils;

@Test
    public void testLaunchJob() throws Exception{
        JobExecution jobExecution = jobLauncherTestUtils.launchJob(
                new JobParametersBuilder().addString("chunkSize", "3").addString("current_date","2016-11-25").toJobParameters()
        );
        commonAssertions(jobLauncherTestUtils.launchJob());
        assertEquals(BatchStatus.COMPLETED, jobExecution.getStatus());
    }

当我运行测试用例时，该过程失败，因为作业参数没有传递到我的工作中。

我正在寻找在春季批次中测试Step Scoped步骤的正确方法。

谢谢， Opensource Explorer

您当前的代码尝试启动并测试作业而不是步骤。根据关于如何测试各个步骤的spring批处理documentation，如何测试tasklet并将上下文注入到tasklet中的一个简单示例更符合以下代码：

TARGET = raspberrypi_qt

@ContextConfiguration @TestExecutionListeners( { DependencyInjectionTestExecutionListener.class, StepScopeTestExecutionListener.class }) @RunWith(SpringJUnit4ClassRunner.class) public class StepScopeTestExecutionListenerIntegrationTests { // This component is defined step-scoped, so it cannot be injected unless // a step is active... @Autowired private YourTaskletClass yourTaskletClass; public StepExecution getStepExection() { StepExecution execution = MetaDataInstanceFactory.createStepExecution(); execution.getExecutionContext().putString("input.data", "foo,bar,spam"); return execution; } @Test public void testYourTaskletClass() { // The tasklet is initialized and some configuration is already set by the MetaDatAInstanceFactory assertNotNull(yourTaskletClass.doSomething()); } }注释只能在1.4及更高版本的弹簧启动版本中使用。有关详细信息，请参阅this博客。

要启动单个步骤，请尝试将代码调整为：

@RunWith(SpringJUnit4ClassRunner.class)
