WebSockets testing
We introduced the topic of WebSockets in the earlier chapters. Now let's see how we can
test them. To do this in plain Java, we will need a WebSocket client implementation; be
sure to add Tyrus to your pom.xml file:
<dependency>
<groupId>org.glassfish.tyrus.bundles</groupId>
<artifactId>tyrus-standalone-client</artifactId>
<scope>test</scope>
<version>1.8.3</version>
</dependency>
For this example, we will use Tyrus as a base code from Chapter 8 , Adding WebSockets .
Our test realizes a simple scenario. Using the REST API, we reserve a seat, and as a We-
bSocket client, we wait for a message broadcasting information concerning new reserva-
tions. Let's look at the code:
@RunAsClient
@RunWith(Arquillian.class)
public class TicketServiceTest {
private static final String WEBSOCKET_URL =
"ws://localhost:8080/ticket-agency-test-websockets/tickets";
private static final String SEAT_RESOURCE_URL =
"http://localhost:8080/ticket-agency-test-websockets/rest/
seat";
@Deployment
public static Archive<?> createTestArchive() { // [1]
return
ShrinkWrap.create(MavenImporter.class).loadPomFromFile("pom.xml")
.importBuildOutput().as(WebArchive.class);
}
@Test
public void shouldReceiveMessageOnBooking() throws
Exception {
// given
