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