suite

public static junit.framework.Test suite()

getProperties

public Properties getProperties()

Description copied from class: AbstractJournalTestCase

Returns properties read from a hierarchy of sources. The underlying properties read from those sources are cached, but a new properties object is returned on each invocation (to prevent side effects by the caller).

In general, a test configuration critically relies on both the properties returned by this method and the appropriate properties must be provided either through the command line or in a properties file.

Overrides:

getProperties in class AbstractJournalTestCase

Returns:

A new properties object.

testRWBits

public void testRWBits()

The RWStore relies on several bit manipulation methods to manage both FixedAllocators and meta allocations.

This test stresses these methods.

test_create_disk01

public void test_create_disk01()
                        throws IOException

Verify normal operation and basic assumptions when creating a new journal using BufferMode.DiskRW.

Throws:

IOException

test_create_emptyFile

public void test_create_emptyFile()
                           throws IOException

Unit test verifies that Options.CREATE may be used to initialize a journal on a newly created empty file.

Throws:

IOException

test_removeAllRWStore

public void test_removeAllRWStore()

Unit tests for optimization when using the RWStore but not using delete markers. In this case, a post-order traversal is used to efficiently delete the nodes and leaves and the root leaf is then replaced.

test_deleteBlocksDiscardedOnReset

public void test_deleteBlocksDiscardedOnReset()

Unit test for an issue where the RWStore did not discard the logged delete blocks in RWStore.reset().

This test writes some records and commits. It then deletes those records and invokes RWStore.reset(). It then re-deletes those records and commits. If we have failed to discard the logged deletes, then we will now have double-deletes in the delete blocks for that commit point. The commit time is noted.

Next, the test creates several more commit points in order to trigger recycling. We verify that the commit record for the commit time noted above is no longer accessible. If the test reaches this point, then we know that double-deletes were not logged.

Note: This test was verified as correctly detecting the bug described in the ticket.

Note: The recycler MUST be used for this test.
