Subject [jira] [Created] (GEODE-4741) DUnit launches ChildVMs with hardcoded heap size
Date Fri, 23 Feb 2018 19:45:00 GMT
Kirk Lund created GEODE-4741:

             Summary: DUnit launches ChildVMs with hardcoded heap size
                 Key: GEODE-4741
             Project: Geode
          Issue Type: Bug
          Components: tests
            Reporter: Kirk Lund

This can result in tests such as PRQueryDUnitTest.testQueryResultsFromMembers passing in gradle
but failing in an IDE such as IntelliJ. 

Adding -Xmx to the JUnit configuration for PRQueryDUnitTest.testQueryResultsFromMembers in
IntelliJ causes this test to start passing. Moving the code in testQueryResultsFromMembers
from the JUnit controller JVM to a ChildVM also causes the test to start passing (because
all 3 datastores are sized equivalently instead of having one be different size).

The better solution is to change DUnit's ProcessManager to launch ChildVMs with the same heap
size as the main JUnit controller JVM. Then they will always be equivalent in all environments.
