--------------------------------
Summary: New DistributedReference JUnit rule for DistributedTests
Key: GEODE-5644
URL: https://issues.apache.org/jira/browse/GEODE-5644
Project: Geode
Issue Type: Wish
Components: tests
Reporter: Kirk Lund
I'd like to add a new DistributedReference JUnit rule for DistributedTests
which would be used similar to an AtomicReference but with a reference that is
useable within every DUnit VM.
The idea is that this would allow us to define something like:
{noformat}
@Rule
public DistributedReference<Cache> cacheReference = new
DistributedReference<>();
@Before
public void setUp() {
getVM(0).invoke(() -> cacheReference.set(new CacheFactory().create());
}
@After
public void tearDown() {
getVM(0).invoke(() -> cacheReference.get().close());
}
{noformat}
And then use the Geode APIs directly within the test without relying on any
custom rules like CacheRule or ClusterStarterRule. This would make tests that
use it more directly dependent on the User APIs and force us to become more
aware of of the shortcomings of that API. If the Geode User API for creating
and closing Cache is so difficult or verbose to use, then this will encourage
us to fix the Geode User API instead of hiding it behind complex JUnit rules.
We could also consider adding support for java.io.Closeable since resources
such as Cache implement Closeable.
