Vertx RoutingContext tests

[Ilya Ivanov]

Hi! I have implementation like:
Router router = Router.router(vertx);
router.get("/protected/user").handler(this::handleUserPage);
--------
private void handleUserPage(RoutingContext ctx) {
...
}

Is is possible to access RoutingContext User via jUnit or some else test frameworks?
Thanks!

Hi,

In your test setup, you can create an HttpServer, a Router and register the required routes for the test case.

It's very cheap and relieves you from playing the mock game.

Doesn't that mean you are not triggering existing routes in this case?

In the case of a unit test, is it important to test all the routes that will present in the final application?

For an integration test yes, you can put them all.

Sorry, I didn't mention that tests are integration ones. OK, got your idea, I have to create all needed routes at the test startup. Thanks!

You can do something like this. In the setup phase create a http server and add your desired handlers/routes.

@RunWith(VertxUnitRunner.class)
public class RestApplicationTest {

  @Rule
  public static RunTestOnContext rule = new RunTestOnContext();

  private int port = 8081;
  private WebClient client;

  @Before
  public void before(TestContext should) {
    Async setup = should.async();

    Router app = Router.router(rule.vertx());

    // add the desired handlers/routes...

    rule.vertx()
      .createHttpServer()
      .requestHandler(app)
      .listen(0)
      .onFailure(should::fail)
      .onSuccess(server -> {
        port = server.actualPort();
        client = WebClient.create(rule.vertx());
        setup.complete();
      });
  }

  @After
  public void after() {
    client.close();
  }

  @Test
  public void callGreetingTest(TestContext should) {
    // Send a request and get a response
    Async test = should.async();
    client.get(port, "localhost", "/greeting")
      .send()
      .onFailure(should::fail)
      .onSuccess(response -> {
        should.assertEquals(401, response.statusCode());
        test.complete();
      });
  }
