ExceptionHandler is not run

[freyliis]

Hi

I have an issue similar to If an exception occurs, the test does not fail, but hangs #52. I added exceptionHandler with fail() but it still does not work, async hangs till timeout:

@RunWith(VertxUnitRunner.class)
public class Test {

    protected final int PORT = 9988;

    @Rule
    public RunTestOnContext runTestOnContext = new RunTestOnContext();

    @Before
    public void setupFakeServer(TestContext ctx) {
        runTestOnContext.vertx()
                .createHttpServer()
                .requestHandler(req -> req.response().end("unexpected"))
                .exceptionHandler(new Handler<Throwable>() {
                    @Override
                    public void handle(Throwable event) {
                        System.err.println("Error");
                        ctx.fail();
                    }
                })
                .listen(PORT, ctx.asyncAssertSuccess());

    }

    @After
    public void tearDown(TestContext ctx) {
        runTestOnContext.vertx().close(ctx.asyncAssertSuccess());
    }

    @org.junit.Test
    public void httpBodyHandler(TestContext ctx) {
        Async async = ctx.async();
        runTestOnContext.vertx().createHttpClient().get(PORT, "localhost", "/", resp -> {
            ctx.assertEquals(200, resp.statusCode());
            resp.bodyHandler(buff -> {
                buff.toJsonObject(); // fails and hangs here
                async.complete();
            });
        }).end();
    }
}

version of vertx-unit: 3.5.1

You're registering the exception handler on the HttpServer, not the Vertx instance/context which the tests are run on.
