Method Details

getCodec

protected abstract Codec getCodec()

Returns the codec to run tests against

getCreatedVersionMajor

protected int getCreatedVersionMajor()

Returns the major version that this codec is compatible with.

applyCreatedVersionMajor

protected final <D extends Directory> D applyCreatedVersionMajor(D d)
                                                          throws IOException

Set the created version of the given Directory and return it.

Throws:

IOException

setUp

public void setUp()
           throws Exception

Description copied from class: LuceneTestCase

For subclasses to override. Overrides must call super.setUp().

Overrides:

setUp in class LuceneTestCase

Throws:

Exception

tearDown

public void tearDown()
              throws Exception

Description copied from class: LuceneTestCase

For subclasses to override. Overrides must call super.tearDown().

Overrides:

tearDown in class LuceneTestCase

Throws:

Exception

addRandomFields

protected abstract void addRandomFields(Document doc)

Add random fields to the provided document.

excludedExtensionsFromByteCounts

protected Collection<String> excludedExtensionsFromByteCounts()

Return the list of extensions that should be excluded from byte counts when comparing indices that store the same content.

testMergeStability

public void testMergeStability()
                        throws Exception

The purpose of this test is to make sure that bulk merge doesn't accumulate useless data over runs.

Throws:

Exception

mergeIsStable

protected boolean mergeIsStable()

testMultiClose

public void testMultiClose()
                    throws IOException

IOException

testRandomExceptions

public void testRandomExceptions()
                          throws Exception

Tests exception handling on write and openInput/createOutput

Throws:

Exception

shouldTestMergeInstance

protected boolean shouldTestMergeInstance()

Returns false if only the regular fields reader should be tested, and true if only the merge instance should be tested.

maybeWrapWithMergingReader

protected final DirectoryReader maybeWrapWithMergingReader(DirectoryReader r)
                                                    throws IOException

testCheckIntegrityReadsAllBytes

public void testCheckIntegrityReadsAllBytes()
                                     throws Exception

This test is the best effort at verifying that checkIntegrity doesn't miss any files. It tests that the combination of opening a reader and calling checkIntegrity on it reads all bytes of all files.

Throws:

Exception
