AllClusterExecutorTest.testExecutorTriConsumerTimeoutException random failures ------------------------------------------------------------------------------ Key: ISPN-10086 URL: https://issues.jboss.org/browse/ISPN-10086 Project: Infinispan Issue Type: Bug Components: Test Suite - Core Affects Versions: 10.0.0.Beta3, 9.4.11.Final Reporter: Dan Berindei Priority: Major Labels: testsuite_stability Fix For: 10.0.0.Beta4, 9.4.12.Final When running tests in parallel, the remote request may complete before the thread that sent the request resumes. Because the scheduled executor is mocked to return {{null}}, this leads to a {{NullPointerException}}: {noformat} 09:43:41,995 ERROR (testng-Test:[]) [TestSuiteProgress] Test failed: org.infinispan.manager.AllClusterExecutorTest.testExecutorTriConsumerTimeoutException java.lang.NullPointerException: null at org.infinispan.remoting.transport.AbstractRequest.setTimeoutFuture(AbstractRequest.java:94) ~[classes/:?] at org.infinispan.remoting.transport.AbstractRequest.setTimeout(AbstractRequest.java:55) ~[classes/:?] at org.infinispan.remoting.transport.jgroups.JGroupsTransport.invokeCommand(JGroupsTransport.java:831) ~[classes/:?] at org.infinispan.manager.impl.AllClusterExecutor.submitConsumer(AllClusterExecutor.java:182) ~[classes/:?] at org.infinispan.manager.ClusterExecutor.submitConsumer(ClusterExecutor.java:116) ~[classes/:?] at org.infinispan.manager.Test$17.call(AllClusterExecutorTest.java:402) ~[test-classes/:?] at org.infinispan.test.TestingUtil.withCacheManagers(TestingUtil.java:1601) ~[test-classes/:?] at org.infinispan.manager.AllClusterExecutorTest.testExecutorTriConsumerTimeoutException(AllClusterExecutorTest.java:382) ~[test-classes/:?] {noformat} The problem may be that the test calls {{Mockito.verify()}} from the consumer twice, once for each node, instead of doing it only on the remote node.
