Methods

Modifier and Type	Method and Description
void	setUp()
void	tearDown()
void	test_memoryLeakWithExplicitClose() Look for a memory leak when the test calls AbstractJournal.close() explicitly.
void	test_memoryLeakWithoutExplicitClose() Look for a memory leak when the test DOES NOT call AbstractJournal.close() explicitly and instead relies on the JVM to invoke finalized() on the Journal.

test_memoryLeakWithExplicitClose

public void test_memoryLeakWithExplicitClose()
                                      throws InterruptedException

Look for a memory leak when the test calls AbstractJournal.close() explicitly.

Throws:

InterruptedException

test_memoryLeakWithoutExplicitClose

public void test_memoryLeakWithoutExplicitClose()
                                         throws InterruptedException

Look for a memory leak when the test DOES NOT call AbstractJournal.close() explicitly and instead relies on the JVM to invoke finalized() on the Journal.

Note: You SHOULD NOT need to close the Journal. Once it is no longer strongly referenced it SHOULD get finalized(). This MAY be set to [true] to verify that the journal is properly shutting down all of its thread pools, but it MUST be [false] for CI since the whole purpose of this test is to verify that Journals are eventually finalized() if the application no longer holds a strong reference to the journal.

Throws:

InterruptedException
