Method Detail

suite

public static Test suite()

A unit test suite for JUnit

Returns:

The test suite

main

public static void main(java.lang.String[] args)

The main program for the BlobTest class

Parameters:

args - The command line arguments

testHexMethods

public void testHexMethods()

Test Hexa methods conversion in the blob data

testClob

public void testClob()

Test method for clobs.

testBlobCreation

public void testBlobCreation()

Basic test to retrieve a blob and validate its content

testBlobs

public void testBlobs()

Test a number of files to be copied and transfer and retrieved to the database. The test fails if a single file test has failed, but a more in depth results is displayed

See Also:

pTestCopy, pTestBibBlobStorage, displayResults

displayResults

public void displayResults(java.lang.String iamtested,
                           boolean copy,
                           boolean swithblob,
                           boolean swithbytes)

Display basic results on testing

Parameters:

iamtested - is the file that was tested

copy - isSuccess

swithblob - result of test with blob

swithbytes - result of test with bytes

pTestCopy

public boolean pTestCopy(java.lang.String storeFile)
                  throws java.io.IOException

Just copy a file to see if no data is lost. Useful for binaries and special encoded files

Parameters:

storeFile - target file to copy

Returns:

true if size of copied file and original files are same.

Throws:

java.io.IOException - if read or write fails on targer storeFile

pTestBigBlobStorage

public boolean pTestBigBlobStorage(java.lang.String storeFile)
                            throws java.io.IOException,
                                   java.sql.SQLException

Send a file to database and retrieve it as a Blob object

Parameters:

storeFile - target file to manipulate as a Blob

Returns:

true if size of stored,retrieved file is same as original

Throws:

java.io.IOException - if write or read fails from target files

java.sql.SQLException - when talking to the database

pTestBlobWithBytes

public boolean pTestBlobWithBytes(java.lang.String storeFile)
                           throws java.io.IOException,
                                  java.sql.SQLException

Test implementation of blobs without having to use the code specific to cjdbc. This is exactly the same test as above without the call for the new instance method.

Parameters:

storeFile - the file to test

Returns:

true if the test was successful.

Throws:

java.io.IOException - if problems reading blob

java.sql.SQLException - if sql problem on the server side

pTestBlobBytes

private boolean pTestBlobBytes(java.lang.String storeFile,
                               boolean callBlobMethods)

readBinary

static byte[] readBinary(java.io.File file)
                  throws java.io.IOException

ReadBinary data from the file. Tested ok with writeBinary param file destination target
