Method Summary

Modifier and Type	Method and Description
static junit.framework.Test	suite()
void	testDerby3735() A regression test for DERBY-3735.
void	testDerby3781() Tests that trying to move past the end of the stream leaves the stream object in a consistent state, and can be repositioned again after the failed reposition attempt.
void	testPositionAfterEOFRead() Verifies that reading after EOF doesn't change the position.
void	testPositionAfterEOFReadArray() Verifies that reading after EOF doesn't change the position.
void	testReadEverythingInOneGo() Reads the whole stream repeatedly in one go, and resets it after each read.
void	testRepositionBackwards()
void	testRepositionForwards()
void	testSimpleReadSequence() Executes a simple read sequence against the lower case modern latin alphabet, which involves some repositioning.

Method Detail

testPositionAfterEOFRead

public void testPositionAfterEOFRead()
                              throws java.io.IOException,
                                     org.apache.derby.iapi.error.StandardException

Verifies that reading after EOF doesn't change the position.

Throws:

java.io.IOException

org.apache.derby.iapi.error.StandardException

testPositionAfterEOFReadArray

public void testPositionAfterEOFReadArray()
                                   throws java.io.IOException,
                                          org.apache.derby.iapi.error.StandardException

Verifies that reading after EOF doesn't change the position.

Throws:

java.io.IOException

org.apache.derby.iapi.error.StandardException

testReadEverythingInOneGo

public void testReadEverythingInOneGo()
                               throws java.io.IOException,
                                      org.apache.derby.iapi.error.StandardException

Reads the whole stream repeatedly in one go, and resets it after each read.

Throws:

java.io.IOException

org.apache.derby.iapi.error.StandardException

testRepositionForwards

public void testRepositionForwards()
                            throws java.io.IOException,
                                   org.apache.derby.iapi.error.StandardException

Throws:

java.io.IOException

org.apache.derby.iapi.error.StandardException

testRepositionBackwards

public void testRepositionBackwards()
                             throws java.io.IOException,
                                    org.apache.derby.iapi.error.StandardException

Throws:

java.io.IOException

org.apache.derby.iapi.error.StandardException

testSimpleReadSequence

public void testSimpleReadSequence()
                            throws java.io.IOException,
                                   org.apache.derby.iapi.error.StandardException

Executes a simple read sequence against the lower case modern latin alphabet, which involves some repositioning.

Throws:

java.io.IOException

org.apache.derby.iapi.error.StandardException

testDerby3735

public void testDerby3735()
                   throws java.io.IOException,
                          org.apache.derby.iapi.error.StandardException

A regression test for DERBY-3735.

If the bug is present, the repositioning will cause an EOF-exception to be thrown in skipFully.

Throws:

java.io.IOException

org.apache.derby.iapi.error.StandardException

testDerby3781

public void testDerby3781()
                   throws java.io.IOException,
                          org.apache.derby.iapi.error.StandardException

Tests that trying to move past the end of the stream leaves the stream object in a consistent state, and can be repositioned again after the failed reposition attempt.

Issue logged in Jira as DERBY-3781

Throws:

java.io.IOException - if reading the stream fails unexpectedly

org.apache.derby.iapi.error.StandardException - will never happen
