All Implemented Interfaces:

IProxyTest, junit.framework.Test

public class TestCommitHistory
extends ProxyTestCase<Journal>

Test the ability to get (exact match) and find (most recent less than or equal to) historical commit records in a Journal. Also verifies that a canonicalizing cache is maintained (you never obtain distinct concurrent instances of the same commit record).

Methods

Modifier and Type	Method and Description
void	assertEquals(ICommitRecord expected, ICommitRecord actual) Compare two ICommitRecords for equality in their data.
void	test_behaviorBeforeAnythingIsCommitted() Test that AbstractJournal.getCommitRecord(long) returns null if invoked before anything has been committed.
void	test_canonicalizingCache() Test verifies that exact match and find always return the same reference for the same commit record (at least as long as the test holds a hard reference to the commit record of interest).
void	test_commitRecordIndex_find() Tests for finding (less than or equal to) historical commit records using the commit record index.
void	test_commitRecordIndex_restartSafe() Tests whether the CommitRecordIndex is restart-safe.
void	test_objectCache() Test of the canonicalizing object cache used to prevent distinct instances of a historical index from being created.
void	test_recoverCommitRecord() Test the ability to recover a ICommitRecord from the CommitRecordIndex.
void	test_recoverCommitRecordNoHistory() Test the ability to recover a ICommitRecord from the CommitRecordIndex.

Method Detail

assertEquals

public void assertEquals(ICommitRecord expected,
                ICommitRecord actual)

Compare two ICommitRecords for equality in their data.

Parameters:

expected -

actual -

test_behaviorBeforeAnythingIsCommitted

public void test_behaviorBeforeAnythingIsCommitted()
                                            throws IOException

Test that AbstractJournal.getCommitRecord(long) returns null if invoked before anything has been committed.

Throws:

IOException

test_recoverCommitRecord

public void test_recoverCommitRecord()

Test the ability to recover a ICommitRecord from the CommitRecordIndex.

test_recoverCommitRecordNoHistory

public void test_recoverCommitRecordNoHistory()

Test the ability to recover a ICommitRecord from the CommitRecordIndex. A second commit should be void and therefore the previous record should be retrievable.

test_commitRecordIndex_restartSafe

public void test_commitRecordIndex_restartSafe()

Tests whether the CommitRecordIndex is restart-safe.

test_commitRecordIndex_find

public void test_commitRecordIndex_find()
                                 throws IOException

Tests for finding (less than or equal to) historical commit records using the commit record index. This also tests restart-safety of the index with multiple records (if the store is stable). The minReleaseAge property has been added to test historical data protection, and not just the retention of the CommitRecords which currently are erroneously never removed.

Throws:

IOException

test_canonicalizingCache

public void test_canonicalizingCache()

Test verifies that exact match and find always return the same reference for the same commit record (at least as long as the test holds a hard reference to the commit record of interest).

test_objectCache

public void test_objectCache()

Test of the canonicalizing object cache used to prevent distinct instances of a historical index from being created. The test also verifies that the historical named index is NOT the same instance as the current unisolated index by that name.
