Question

我正在研究一个样本，以演示弹簧批处理的单元测试。在maven构建过程中，我可以看到单元测试成功执行，但是构建仍然失败，并出现以下错误。

批处理测试成功执行。下面是输出

执行单位文本后，构建失败并显示以下错误

Answer 1

如果使用Spring Batch v4.1 +，则可以在测试类上添加@SpringBatchTest批注，它将自动将JobLauncherTestUtils bean添加到测试上下文：

@RunWith(SpringRunner.class)
@SpringBatchTest
@ContextConfiguration(classes = {JobConfiguration.class})
public class JobTest {

  @Autowired
  private JobLauncherTestUtils jobLauncherTestUtils;

  // use jobLauncherTestUtils in test methods

}

请查看What's new部分以获取完整示例。您将在unit testing部分中找到更多详细信息。

很遗憾，您的测试未执行。由于启动时应用程序上下文失败，因此无法启动。要修复测试，您需要添加遗漏的依赖项（JobLauncherTestUtils）。为此，我建议添加测试上下文：

@RunWith(SpringRunner.class)
@SpringBootTest(classes = {TransactionBatchApplication.class, TransactionBatchTests.TestConfig.class})
//@Transactional
@TestPropertySource(properties = {"spring.batch.job.enabled=false"})
public class TransactionBatchTests {

    @Autowired
    private JobLauncherTestUtils jobLauncherTestUtils;

    @Autowired
    private TransactionEntryRepository transactionEntryRepository;

    @Test
    public void testJob() throws Exception {
        JobExecution jobExecution = jobLauncherTestUtils.launchJob();
        assertThat("COMPLETED").isEqualTo(jobExecution.getExitStatus().getExitCode());
        assertThat(transactionEntryRepository.count()).isEqualTo(18);
    }

    @Configuration
    static class TestConfig {
        @Bean
        JobLauncherTestUtils jobLauncherTestUtils() {
            return new JobLauncherTestUtils();
        }
    }
}

我还由于以下原因禁用了@Transactional：

java.lang.IllegalStateException: Existing transaction detected in JobRepository. Please fix this and try again (e.g. remove @Transactional annotations from client).

我建议更改断言中的值（实际值和预期值）：

assertThat(transactionEntryRepository.count()).isEqualTo(10);

在那之后，检查10是否为有效的期望值，因为实际为18，所以不确定哪个是正确的。

因此，将期望值更改为18后，您将获得绿色。

即使单元测试成功，Maven构建也会失败
