Subject [jira] [Created] (AMQ-4338) MQTTSSLTest has multiple test cases that fail frequently

--------------------------------

             Summary: MQTTSSLTest has multiple test cases that fail frequently
                 Key: AMQ-4338
                 URL: https://issues.apache.org/jira/browse/AMQ-4338
             Project: ActiveMQ
          Issue Type: Bug
          Components: Test Cases
            Reporter: Kevin Earls
            Priority: Minor


MQTTSSLTest has multiple different test cases (including testSendAndReceiveExactlyOnce, testSendAndReceiveLargeMessages,
testSendAndReceiveMQTT, testSendAtLeastOnceReceiveAtMostOnce, testSendAtLeastOnceReceiveExactlyOnce,
testSendJMSReceiveMQTT, testSendMQTTReceiveJMS) which fail fairly frequently because of a
hang on the provider.connect() call in initializeConnection() as shown in the stacktrace below.


Another problem with this test is it was giving a misleading error when run under Hudson,
showing that the test that followed it (MQTTTest) was failing instead.  I think this was because
of the way it was using AutoFailTestSupport.  I will attach a patch which removes that and
uses timeouts on @Test annotations instead.

testSendAndReceiveLargeMessages(org.apache.activemq.transport.mqtt.MQTTSSLTest)  Time elapsed:
30.004 sec  <<< ERROR!
java.lang.Exception: test timed out after 30000 milliseconds

Results :

Tests in error:
  MQTTSSLTest>AbstractMQTTTest.testSendAndReceiveLargeMessages:247->initializeConnection:60
