Unit Testing vertx-web verticle...

[Deven Phillips]

I have a verticle which uses vertx-web to create a Router. The router registers 2 endpoints:

PUT /rest/entry

GET /rest/winner

I am trying to unit test this using the following tests:

package us.juggl.raffle;


import io.vertx.core.Vertx;
import io.vertx.core.http.HttpClient;
import io.vertx.core.http.HttpClientRequest;
import io.vertx.core.http.HttpClientResponse;
import io.vertx.ext.unit.Async;
import io.vertx.ext.unit.TestContext;
import org.junit.Before;
import org.junit.Test;
import org.junit.runner.RunWith;


/**
 * Created by dphillips on 9/10/15.
 */
@RunWith(io.vertx.ext.unit.junit.VertxUnitRunner.class)
public class MainTest {
    private Vertx vertx;


    @Before
    public void setUp() throws Exception {
        vertx = Vertx.vertx();
        vertx.deployVerticle(new Main());
    }

    @Test
    public void testAddValidEntry(TestContext context) {
        final Async async = context.async();
        HttpClient client = vertx.createHttpClient();
        HttpClientRequest req = client.put(8080, "127.0.0.1", "/rest/entry");
        req.handler((HttpClientResponse response) -> {
            context.assertNotNull(response);
            context.assertTrue(response.statusCode()==202);
            async.complete();
        });
        req.exceptionHandler(exception -> {
            context.fail(exception.getLocalizedMessage());
            async.complete();
        });
        req.end("{\"given_name\": \"Deven\", \"family_name\": \"Phillips\"}");
    }

    @Test
    public void testGetWinner(TestContext context) {
        final Async async = context.async();
        vertx.createHttpClient().put(8080, "localhost", "/rest/entry").handler(response -> {
            context.assertNotNull(response);
            vertx.createHttpClient().get(8080, "localhost", "/rest/winner").handler(resp -> {
                context.assertNotNull(resp);
                async.complete();
            }).end();
        }).end("{\"given_name\": \"Deven\", \"family_name\": \"Phillips\"}");
    }


    @Test
    public void testAddInvalidEntry(TestContext context) {
        final Async async = context.async();
        HttpClient client = vertx.createHttpClient();
        HttpClientRequest req = client.put(8080, "localhost", "/rest/entry");
        req.handler(response -> {
            context.assertNotNull(response);
            async.complete();
        });
        req.end("{\"given_nOME\": \"Deven\", \"family_nOME\": \"Phillips\"}");
    }
}

The problem is that I always get a 404 error for every test. Any suggestions on what I am doing wrong?

The code works when I run the application and I get good responses (202 or 200 respectively), but not when doing the unit tests.

Thanks in advance!!!

OK, I figured it out... The @Before method was causing multiple instances of the Verticle to attempt to deploy and that caused a Bind exception because the port was in use... Added an @After method which shuts down Vert.x between tests and all is now passing...
