API 测试 + 事务回滚答案

【问题标题】：API test + transactional rollbackAPI 测试 + 事务回滚
【发布时间】：2017-01-20 12:12:20
【问题描述】：

我有一个这样的测试：

@Test
@Transactional
public void when_EnteredRegisteredProductionOrder_and_RegisteredStaffSignature_then_201_and_ProductionOrderRegistered() {
    //language=JSON
    String startProductionOrder = "{\n" +
            "  \"productionOrder\": \"1700281\",\n" +
            "  \"staffCodeSignature\": \"00000425\"\n" +
            "}";

    given()
            .body(startProductionOrder)
            .accept(ContentType.JSON)
            .contentType(ContentType.JSON)
            .when()
            .post(commandPath)
            .then().statusCode(201);


    ProductionOrder po = productionOrderRepo.findOneByCode("1700281");
    assertThat(po.getCode(), is("1700281"));
}

我的目的是使用 reassured 从头到尾测试 REST API。正如您可以想象的那样，从控制器开始的每个命令都使用@Transactional 进行注释。问题是测试不会自动回滚。调试日志显示比（我删除了很多部分，因为它太长无法发布）：

这似乎是一个新的应用程序上下文（并使用了胎面）。我怎样才能完成上述任务？这是使用@AfterTranscation 并为每次测试清理我的数据库的唯一方法吗？

【问题讨论】：

目前我使用 @Sql 和 ExecutionPhase.AFTER_TEST_METHOD 在每次测试后截断表。但是，如果我尝试并行运行它们，这将不起作用。所以我认为事务回滚仍然有用（而且更快）。
您找到解决方案了吗？
不...我想我会在截止日期后重新访问它

标签： java spring spring-boot integration-testing spring-transactions

【解决方案1】：

@Transactional 只能在同一个线程中工作，因此 Spring 提供的回滚只对持久在事务开始的线程上的对象起作用。

您放心的测试将执行集成测试，并将在另一个线程上命中您的 Spring 上下文。因此，尽管您的放心测试能够看到您的测试设置中持久存在的对象，但 Spring 将永远无法自动清理您的放心测试中持久存在的资源。

解决此问题的唯一方法是自己在测试中删除实体（使用 Junit 规则，或清理测试设置中的任何状态）。

【解决方案2】：

我一直在努力解决这个问题，并设法找到了解决方法。该问题确实是由于 JUnit 测试在与嵌入式 servlet 容器不同的线程中运行的事实引起的。这意味着打开了两个事务和数据库连接，彼此不知道。解决方法是将在 JUnit 测试中打开的事务传播到 servlet 容器（使用过滤器）：

@Transactional
public class MyTest {
    private static final String[] FIELD_NAMES = {"resources", "synchronizations", "currentTransactionName", "currentTransactionReadOnly", "currentTransactionIsolationLevel", "actualTransactionActive"};
    private static final Field[] FIELDS = new Field[FIELD_NAMES.length];
    private static final Object[] FIELD_VALUES = new Object[FIELD_NAMES.length];

    @Before
    public void copyTransactionThreadLocals() {
        for (int i=0; i<FIELD_NAMES.length; i++) {
            Field field = ReflectionUtils.findField(TransactionSynchronizationManager.class,FIELD_NAMES[i]);
            field.setAccessible(true);
            FIELD_VALUES[i] = ((ThreadLocal)ReflectionUtils.getField(field,null)).get();
            FIELDS[i] = field;
        }
    }

    @Configuration
    static class Config {
        @Bean
        public Filter transactionFilter() {
            return new OncePerRequestFilter() {
                @Override
                protected void doFilterInternal(HttpServletRequest request, HttpServletResponse response, FilterChain filterChain) throws ServletException, IOException {
                    for (int i=0; i<FIELD_NAMES.length; i++) {
                        ((ThreadLocal)ReflectionUtils.getField(FIELDS[i],null)).set(FIELD_VALUES[i]);
                    }
                    filterChain.doFilter(request,response);
                }
            };
        }
    }
}

请注意，上述代码是使用反射复制无法访问的静态字段的 hack。

【解决方案3】：

通过这些集成测试，Spring 正在重用它的测试上下文，并且旧事务可能会保留下来，并由于之前测试的状态而导致测试以奇怪的方式失败。如果您看到单独运行时通过的测试在一起运行时失败，则使用 @DirtiesContext 注释测试。这让 Spring 知道它应该丢弃测试上下文而不是重用它。
