All Implemented Interfaces:

junit.framework.Test

public class TestRandomBlockOps
extends AbstractRepositoryTestCase

Unit tests for random block IO include read, write, overwrite (aka update), and delete. There are also some unit tests for atomic append after random write since random writes can leave "holes" in files.

Method Detail

test_write01

public void test_write01()
                  throws IOException

Tests random write of a block, read back of the data, overwrite of the same block, atomic append after the random write, and random delete.

Throws:

IOException

test_write02

public void test_write02()
                  throws IOException

Unit test where a block is written using a random write, replaced with an empty block, and then replaced with a non-empty block. The test verifies that the empty block in fact replaces the block (rather than being interpreted as a delete of the block).

Throws:

IOException

test_deleteH

public void test_deleteH()
                  throws IOException

Test for delete of the head block.

Throws:

IOException

test_stress

public void test_stress()

A small stress test for a single file version.
