Method Detail

setUp

public void setUp()
           throws Exception

Overrides:

setUp in class SampleDataRepositoryTestCase

Exception

tearDown

public void tearDown()
              throws Exception

Overrides:

tearDown in class LocalDiskRepositoryTestCase

Throws:

Exception

                    throws IOException

Test constructor for exceptions, default settings, initialization.

Throws:

IOException

testModifySettings

public void testModifySettings()

Change default settings and verify them.

testWriteEmptyPack1

public void testWriteEmptyPack1()
                         throws IOException

Write empty pack by providing empty sets of interesting/uninteresting objects and check for correct format.

Throws:

IOException

testWriteEmptyPack2

public void testWriteEmptyPack2()
                         throws IOException

Write empty pack by providing empty iterator of objects to write and check for correct format.

Throws:

IOException

testNotIgnoreNonExistingObjects

public void testNotIgnoreNonExistingObjects()
                                     throws IOException

Try to pass non-existing object as uninteresting, with non-ignoring setting.

Throws:

IOException

testIgnoreNonExistingObjects

public void testIgnoreNonExistingObjects()
                                  throws IOException

                                                    ParseException

Try to pass non-existing object as uninteresting, with ignoring setting. Use a repo with bitmap indexes because then PackWriter will use PackWriterBitmapWalker which had problems with this situation.

Throws:

IOException

ParseException

testWritePack1

public void testWritePack1()
                    throws IOException

Create pack basing on only interesting objects, then precisely verify content. No delta reuse here.

Throws:

IOException

testWritePack1NoObjectReuse

public void testWritePack1NoObjectReuse()
                                 throws IOException

Test writing pack without object reuse. Pack content/preparation as in testWritePack1().

Throws:

IOException

testWritePack2

public void testWritePack2()
                    throws IOException

Create pack basing on both interesting and uninteresting objects, then precisely verify content. No delta reuse here.

Throws:

public void testWritePack2DeltasReuseRefs()
                                   throws IOException

MissingObjectException

testWritePack4

public void testWritePack4()
                    throws IOException
