Testcontainer 不适用于 Kotlin 和 Quarkus - 连接到服务器时监控线程出现异常 mongo:27017

Question

我正在尝试使用 Quarkus、Kotlin、MongoDB[ 创建一个简单的待办事项应用程序=29=] 和 TestContainers。我正在使用测试容器来测试我与 mongodb 的集成。不幸的是，我的测试没有像我预期的那样工作。这是我的测试用例，我不确定出了什么问题。我可以从日志中看到 mongodb 的测试容器已启动，我正在将 replicaSetUrl 设置到 属性.

@QuarkusTest
class TodoResourceIT {

    @Container
    private val mongoDbContainer: MongoDBContainer = MongoDBContainer("mongo:4.2").withExposedPorts(27017)

    init {
        mongoDbContainer.start()
        System.setProperty("quarkus.mongodb.connection-string", mongoDbContainer.replicaSetUrl)
    }
    @Test
    fun shouldReturn200OK() {
        given().header(HttpHeaders.CONTENT_TYPE, MediaType.APPLICATION_JSON)
            .body(Todo("1", "Find", "Find the letter F"))
            .`when`().post("/api/todos").then().statusCode(200)
    }
}

这是我的完整源代码：https://github.com/faskan/todo-kotlin-quarkus

我看过类似的帖子. But the solution works only in Java. Here is my sample implementation using Java which works perfectly fine. https://github.com/faskan/todo-java-quarkus

我现在面临的问题是 Kotlin。

你的 quarkus 是哪个版本？

您可以QuarkusTestResourceLifecycleManager to archieve that, I've already tested it with kotlin and work fine. Here有一个关于如何做到这一点的例子
