Package org.springframework.amqp.rabbit.junit

Class BrokerRunning

  • All Implemented Interfaces:
    org.junit.rules.TestRule
    public final class BrokerRunning
extends org.junit.rules.TestWatcher
    A rule that prevents integration tests from failing if the Rabbit broker application is not running or not accessible. If the Rabbit broker is not running in the background all the tests here will simply be skipped (by default) because of a violated assumption (showing as successful). Usage: 
     @Rule
 public static BrokerRunning brokerIsRunning = BrokerRunning.isRunning();

 @Test
 public void testSendAndReceive() throws Exception {
        // ... test using RabbitTemplate etc.
 }
    The rule can be declared as static so that it only has to check once for all tests in the enclosing test case, but there isn't a lot of overhead in making it non-static.

    Use isRunningWithEmptyQueues(String...) to declare and/or purge test queue(s) when the rule is run.

    Call removeTestQueues(String...) from an @After method to remove those queues (and optionally others).

    If you wish to enforce the broker being available, for example, on a CI server, set the environment variable "RABBITMQ_SERVER_REQUIRED" to true and the tests will fail fast.
