我开始在Vertx的项目中使用TDD并编写了以下测试，但似乎没有来自我创建的服务器的响应并且线程被阻止。如何向localhost服务器发送请求？
@Test
public void testExecuteRequest(TestContext ctx) {
Vertx vertx = Vertx.vertx();
vertx.createHttpServer(new HttpServerOptions().setLogActivity(true))
.requestHandler(httpServerRequest -> httpServerRequest.response().end("callback"))
.listen(7777, "localhost", handler -> {
ctx.async().countDown();
if (handler.succeeded()) {
HttpUtils.executeRequest(vertx.createHttpClient(new HttpClientOptions().setLogActivity(true)),
HttpMethod.GET,
"localhost",
7777, "",
null, null, null)
.subscribe(response -> ctx.assertEquals(200, response.statusCode()),
ctx::fail,
ctx.async()::complete);
} else {
ctx.fail(handler.cause());
}
});
ctx.async().awaitSuccess();
}
它从实用程序类测试方法：
public Observable<HttpClientResponse> executeRequest(HttpClient client, HttpMethod method, String host, Integer
port, String uri, @Nullable byte[] body, @Nullable LinkedMultiValueMap<String, String> headers, @Nullable Integer timeout) {
CompletableFuture<HttpClientResponse> responseFuture = new CompletableFuture<>();
HttpClientRequest request = client.request(method, port, host, uri, responseFuture::complete);
Optional.ofNullable(headers).ifPresent(value -> headers.forEach(request::putHeader));
Optional.ofNullable(body).ifPresent(value -> request.write(Buffer.buffer(body)));
Optional.ofNullable(timeout).ifPresent(request::setTimeout);
request.end();
return Observable.fromFuture(responseFuture);
}
但是当我开始这个测试时，我得到了以下控制台输出：

如何测试我的方法是否正确执行了HTTP请求？
