All Implemented Interfaces:

Test

public class ThreadedXferTest

extends TestCase

Simplistic test case for ThreadedTransfer. Since we are testing a multi-threaded class, the tests are designed to start simple, and grow abusive in an attempt to force out intermittent thread communication problems.

Each test will create a temporary file on the hard disk, containing random data. A ThreadedTransfer is spawned to duplicate that file to some set of mirrors. Then, all mirrors are tested for independantly for equality with the origional file.

Since all files are being stored in the same temporary space (usually a single hard disk) this class is purely a bug test, and a poor gauge for performance testing.

Method Detail

setUp

protected void setUp()
              throws Exception

Creates all temp files. Fills the source file with random data.

Throws:

Exception

testSlurpDuplication

public void testSlurpDuplication()
                          throws IOException

Tests ThreadedTransfer.slurp(InputStream)

Throws:

IOException

testBulkDuplication

public void testBulkDuplication()
                         throws IOException

Tests ThreadedTransfer.write(byte[], int, int)

Throws:

IOException

testByteDuplication

public void testByteDuplication()
                         throws IOException

Tests ThreadedTransfer.write(int)

Throws:

IOException

tearDown

protected void tearDown()
                 throws Exception

Deletes temp files. May throw an Error if a stream is still open, in which case remnants may have to be cleaned up manually.

Throws:

Exception

suite

public static TestSuite suite()
