Question

我正在使用Vert.x 3.5.3。我有这个（简单的）Verticle：

class DialPadVerticle : AbstractVerticle() {
  private companion object : KLogging()

  override fun start(future: Future<Void>) {
    vertx.eventBus().consumer(Address.DIALPAD_COMBINATIONS) { message: Message<Int> ->
      val input = message.body()
      logger.info { "Received: $input" }
      message.reply(JsonObject().put("result", DialPad().combinations(input)))
    }
    future.complete()
  }

  override fun stop(future: Future<Void>) {
    logger.debug { "Stopping ${this.javaClass.simpleName} (${deploymentID()})...DONE" }
    future.complete()
  }
}

...并且我正在尝试使用实验性的vertx-junit5为此构建一个单元测试框架。到目前为止，我有这个：

@ExtendWith(VertxExtension::class)
@DisplayName("Dial pad verticle should...")
internal class DialPadVerticleTest {
  @BeforeEach
  fun prepare(vertx: Vertx, testContext: VertxTestContext) {
    vertx.deployVerticle(DialPadVerticle(), testContext.succeeding())
  }

  @Test
  @Throws(Exception::class)
  @DisplayName("Consume Message<Int> correctly")
  fun `consume message correctly`(vertx: Vertx, testContext: VertxTestContext) {
    vertx.eventBus().send<JsonObject>(Address.DIALPAD_COMBINATIONS, 5) {
      // Assertions.assertThat(it.succeeded()).isTrue()
      testContext.verify {
        testContext.completeNow()
      }
    }
  }
}

但是每次我尝试从IntelliJ中运行它时，我都会得到：

这是vertx-junit5库上的错误吗？我还注意到，如果Verticles依赖于某些外部配置，即使我将正确的DeploymentOptions().setConfig(JsonObject().put(...))作为第二个参数传递给deployVerticle，它也不会读取这些参数。

Answer 1

我运行了您的代码，发现执行从未达到测试方法。

您还需要使用@BeforeEach方法关闭上下文：

@BeforeEach
fun prepare(vertx: Vertx, testContext: VertxTestContext) {
  vertx.deployVerticle(DialPadVerticle(), testContext.succeeding {
    testContext.completeNow()
  })
}

testContext.succeeding仅提供一个AsyncResult处理程序，用于检查结果是否成功，但不会将整个测试上下文标记为已完成。它简化了对中介步骤的检查。

现在测试通过就可以了！

您在某处会有一个最小的复制程序项目吗？
