extends ProxyTestCase<Journal>

Correctness test suite for unisolated writes on one or more indices. The tests in this suite validate that the unisolated writes result in a commit and that the committed data may be read back by an unisolated read task. Some tests write on more than one index in order to verify that the writes and reads are performed against the expected index. The stress test additionally verifies that dirty indices are retained by Name2Addr on its commit list and that writes are NOT lost in large commit groups.

Methods

Modifier and Type	Method and Description
void	test_writeManyIndices() This is an N index stress test designed to verify that all indices receive their writes in a large commit group.
void	test_writeOneIndex() Test creates a named index and writes a set of entries on that index using an unisolated write task.
void	test_writeTwoIndex() Test creates two named indices and writes a set of distinct entries on each index using a single unisolated write task to write on both indices.

Method Detail

test_writeOneIndex

public void test_writeOneIndex()
                        throws InterruptedException,
                               ExecutionException

Test creates a named index and writes a set of entries on that index using an unisolated write task. We verify that a commit occured and then verify that the written data may be read back using an unisolated read task.

Throws:

InterruptedException

ExecutionException

test_writeTwoIndex

public void test_writeTwoIndex()
                        throws InterruptedException,
                               ExecutionException

Test creates two named indices and writes a set of distinct entries on each index using a single unisolated write task to write on both indices. We verify that a commit occured and then verify that the written data may be read back using a single unisolated read task to read from both indices.

Throws:

InterruptedException

ExecutionException

test_writeManyIndices

public void test_writeManyIndices()
                           throws InterruptedException,
                                  ExecutionException

This is an N index stress test designed to verify that all indices receive their writes in a large commit group. N SHOULD be choosen to be larger than the #of indices in the LRU cache maintained by Name2Addr.

Note: This does all writes in a single task in order to simulate a large commit group and stress the commit list mechanism used by Name2Addr. However, it does not matter whether the data are validated by a single read task or by multiple read tasks.

Throws:

ExecutionException

InterruptedException
