Vertx http post client runs forever - http-post

Question

I have the following Vertx Route setup:
router.post("/api/apple/")
.handler(e -> {
e.response()
.putHeader("content-type", "application/json")
.setStatusCode(200)
.end("hello");
})
.failureHandler(ctx -> {
LOG.error("Error: "+ ctx.response().getStatusMessage());
ctx.response().end();
});
vertx.createHttpServer().requestHandler(router::accept)
.listen(config().getInteger("http.port", 8081), result -> {
if (result.succeeded()) {
LOG.info("result succeeded in my start method");
future.complete();
} else {
LOG.error("result failed");
future.fail(result.cause());
}
});
When I call this from my Java test client:
Async async = context.async();
io.vertx.core.http.HttpClient client = vertx.createHttpClient();
HttpClientRequest request = client.post(8081, "localhost", "/api/apple/", response -> {
async.complete();
LOG.info("Some callback {}",response.statusCode());
});
String body = "{'username':'www','password':'www'}";
request.putHeader("content-length", "1000");
request.putHeader("content-type", "application/x-www-form-urlencoded");
request.write(body);
request.end();
The client keeps running and then the client times out. Seems like it is not able to find the endpoint on localhost:8081/api/apple

You didn't deploy your verticle defining routes in the test scope. Here is a working snippet:
public class HttpServerVerticleTest extends VertxTestRunner {
private WebClient webClient;
private HttpServerVerticle httpServer;
private int port;
#Before
public void setUp(TestContext context) throws IOException {
port = 8081;
httpServer = new HttpServerVerticle(); // the verticle where your routes are registered
// NOTICE HERE
vertx.deployVerticle(httpServer, yourdeploymentOptions, context.asyncAssertSuccess());
webClient = WebClient.wrap(vertx.createHttpClient());
}
#After
public void tearDown(TestContext testContext) {
webClient.close();
vertx.close(testContext.asyncAssertSuccess());
}
#Test
public void test_my_post_method(TestContext testContext) {
Async http = testContext.async();
String body = "{'username':'www','password':'www'}";
webClient.post(port, "localhost", "/api/apple/")
//.putHeader("Authorization", JWT_TOKEN)
.putHeader("content-length", "1000");
.putHeader("content-type", "application/x-www-form-urlencoded");
.sendJson(Buffer.buffer(body.getBytes()), requestResponse -> {
if (requestResponse.succeeded()) {
testContext.assertTrue(requestResponse.result().statusCode() == HttpResponseStatus.OK.code());
testContext.assertTrue(requestResponse.result().body().getString().equals("hello"));
} else {
testContext.fail(requestResponse.cause());
}
http.complete();
});
}
}
