升级到 spring boot 2.2 后，Springboot WebFlux 测试失败

Question

我有一些 Springboot 集成测试在 Springboot 2.1 中运行良好，但现在我已经升级到 Springboot 2.2，它们失败了。使用默认的 spring-boot parent 依赖管理。一些曾经有效的失败测试就像这个例子一样简单：

...
@RunWith(SpringRunner.class)
@SpringBootTest(
 webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT,
 properties = {"spring.sleuth.enabled=false"})
@Import({AccountApiClient.class,...})
@DirtiesContext
@AutoConfigureStubRunner(stubsMode = StubRunnerProperties.StubsMode.CLASSPATH,
 ids = {"my.org.com:account-service:+:stubs:9021"},
 consumerName = "AccountServiceV2",
 stubsPerConsumer = true)
public class AccountsClientTest {

@Autowired
AccountService accountService;

@Test
public void verifyAccountsShouldReturnEmpty() {
    Mono<List<Accounts>> acc = accountService.getAccounts(new AccountId(ACC_ID));
    assertThat(acc.block(), hasSize(0));
 }
 ...

升级前，该测试按预期通过，但升级后失败并出现以下错误：

[ERROR] verifyAccountsShouldReturnEmpty  Time elapsed: 0.004 s  <<< ERROR!
reactor.core.Exceptions$ReactiveException: java.lang.AssertionError: Spring Context [org.springframework.boot.web.servlet.context.AnnotationConfigServletWebServerApplicationContext@7d605944, started on Tue Aug 18 10:00:09 CEST 2020, parent: org.springframework.context.annotation.AnnotationConfigApplicationContext@a035db9] is not yet refreshed. This is unexpected. Reactor Context is [Context0{}] and name is [blocking]

升级后，我有很多具有类似行为的测试。它在行 assertThat(acc.block(), hasSize(0));

上失败

可能是什么原因造成的？

更新

我尝试按照评论中的建议更改测试以使用 StepVerifier，但没有成功：

@Test
public void verifyAccountsShouldReturnEmpty() {
  StepVerifier.create(
      accountService.getAccounts(new AccountId(ACC_ID)))
      .expectNext(Collections.emptyList())
      .verifyComplete();
}

错误的结尾刚刚更改为：parent: org.springframework.context.annotation.AnnotationConfigApplicationContext@985b9f6] is not yet refreshed. This is unexpected. Reactor Context is [Context0{}] and name is [stepVerifier ])) 这似乎与使用块的问题相同，但现在使用 StepVerifier。

谢谢。

Answer 1

我终于设法解决了这个问题，不幸的是不确定根本原因，但修复它的方法是从 @SpringBootTest 注释中删除属性并使用它的默认值。显然，随着导致问题的依赖项升级，其中的内容发生了变化。

所以它可以像这样工作：

...
@RunWith(SpringRunner.class)

// below annotation properties were removed which fixed the tests...
@SpringBootTest

@Import({AccountApiClient.class,...})
@DirtiesContext
@AutoConfigureStubRunner(stubsMode = StubRunnerProperties.StubsMode.CLASSPATH,
 ids = {"my.org.com:account-service:+:stubs:9021"},
 consumerName = "AccountServiceV2",
 stubsPerConsumer = true)
public class AccountsClientTest {

Answer 2

添加后我遇到了类似的问题

    <dependency>
      <groupId>org.springframework.cloud</groupId>
      <artifactId>spring-cloud-starter-sleuth</artifactId>
    </dependency>

我通过删除@DirtiesContext

解决了这个问题
