没有为参数[io.vertx.ext.unit.TestContext arg0]注册ParameterResolver [英] No ParameterResolver registered for parameter [io.vertx.ext.unit.TestContext arg0]

问题描述

我正在尝试为与vertx相关的东西编写一个测试用例.

I am trying to write a test case for vertx related stuff.

这是我的代码

import org.junit.jupiter.api.AfterAll;
import org.junit.jupiter.api.BeforeAll;
import org.junit.jupiter.api.Test;
import org.junit.runner.RunWith;

import io.vertx.core.Vertx;
import io.vertx.core.http.HttpClient;
import io.vertx.core.http.HttpServer;
import io.vertx.ext.unit.Async;
import io.vertx.ext.unit.TestContext;
import io.vertx.ext.unit.junit.VertxUnitRunner;

@RunWith(VertxUnitRunner.class)
public class MyJUnitTest {

static Vertx vertx;
static HttpServer server;

@BeforeAll
public static void before(TestContext context) {
    Async async = context.async();
    vertx = Vertx.vertx();
    server = vertx.createHttpServer().requestHandler(req -> req.response().end("foo")).listen(8080,
            context.asyncAssertSuccess());
    System.out.println("Service started....");
    async.complete();
}

@AfterAll
public static void after(TestContext context) {
    vertx.close(context.asyncAssertSuccess());
}

@Test
public void test1(TestContext context) {
    // Send a request and get a response
    HttpClient client = vertx.createHttpClient();
    Async async = context.async();
    client.getNow(8080, "localhost", "/", resp -> {
        resp.bodyHandler(body -> {
            context.assertEquals("foo", body.toString());
            client.close();
            async.complete();
        });
    });
}}

出现以下错误:

请帮助解决此问题.

推荐答案

问题是您没有用vertx信息包装"文本.

The problem is that you are not "wrapping" the text with vertx info.

请检查文档: https://vertx.io/preview/docs/vertx-junit5/java/

此外，您应该在方法中使用注释@ExtendWith(VertxExtension.class)而不是RunWith()来使用该参数.

Also you should use the annotation @ExtendWith(VertxExtension.class) instead of RunWith() to use that parameter in your methods.
