Method Summary

private void	assertArrayIndexOutOfBounds(String what, TestFileDescriptor.IO io, byte[] buf, int start, int length) Check that an IO operation throws an exception.
private void	assertBecomesReady(FileDescriptor fd)
void	setUp() Sets up the fixture, for example, open a network connection.
void	tearDown() Tears down the fixture, for example, close a network connection.
void	testArrayEOF() Test closing a pipe.
void	testArrayIO() Test passing arrays of bytes through a pipe.
void	testArraySubBufferRead() Test a sub-buffer read.
void	testArraySubBufferWrite() Test a sub-buffer write.
void	testByteEOF() Test closing a pipe.
void	testByteIO() Test passing individual bytes through a pipe.
void	testCreate() Try creating a temporary file.
void	testDupPipeOutToIn() Try duping the output of a Pipe back to its input.
void	testInputOutputStreams() Test input and output streams.
void	testNegativeFileDescriptor() See what happens if FileDescriptor is -ve.
void	testOpenEtcPasswd() Try opening a random file and reading it.
void	testReadOutOfBounds() Try performing IO outside of an array's bounds.
void	testReady() Test the ready method, a pipe is only ready if something was written to it.
void	testSeek() Try wondering round the file using seeks.
void	testTwiceClosed() Try closing things twice; second call should do nothing (i.e., no exception).
void	testWriteOutOfBounds()
private void	verifyOutOfBounds(TestFileDescriptor.IO io) Try performing OP with various out-of-bounds array parameters.

Method Detail

setUp

public void setUp()

Description copied from class: TestCase

Sets up the fixture, for example, open a network connection. This method is called before a test is executed.

Overrides:

setUp in class TestCase

tearDown

public void tearDown()

Description copied from class: TestCase

Tears down the fixture, for example, close a network connection. This method is called after a test is executed.

Overrides:

tearDown in class TestCase
