Example 3 with ServiceDiscovery

use of io.vertx.rxjava.servicediscovery.ServiceDiscovery in project georocket by georocket.

the class ServiceTest method discover.

/**
 * Test if a service can be discovered
 * @param context the test context
 */
@Test

}

Example 4 with ServiceDiscovery

use of io.vertx.rxjava.servicediscovery.ServiceDiscovery in project georocket by georocket.

the class ServiceTest method send.

/**
 * Test if a message can be sent and if a consumer receives the message.
 * This method does not test if the message can be sent to only one
 * consumer (instead of all, see {@link #broadcast(TestContext)}),
 * because it's not possible to check if a consumer will not receive a
 * message before the asynchronous test ends.
 * @param context the test context
