Vladimir Blagojevic updated ISPN-220:
-------------------------------------
Description:
During an execution of a test suite TestNG keeps references to all executed test class
instances. Some of our test classes keep references to instantiated caches, cache
managers, and other heavy weight objects thus preventing those references from ever being
garbage collected.
Our test classes should *never* keep references to heavyweight objects other than in a
test method scope. If we must keep reference to a cache or a cache manager in a class
scope these references should be cleared and nulled in a method annotated with
@AfterClass.
Since TestNG does not traverse class hierarchy for invocation of @AfterClass annotated
methods we have to ensure that every @AfterClass method is invoked in test class hierarchy
(i.e call super).
