PatternTesting Exception (patterntesting-exception) is a framework round about exceptions. It wraps some common exception (like IOException) to provide some more information as the original exception (e.g. the filename with the absolute pathname). On the other it allows you to provoke exceptions for better testing.

The newest version!

package patterntesting.exception.sql;

import java.sql.SQLException;
import java.sql.Statement;


/**
 * An {@link java.sql.SQLException} itself does not contain any information about
 * the executed (and failed) SQL query. The necessary data is contained
 * in the {@link java.sql.Statement} that initiated the execution of the query. 
 * The SqlSyntaxExceptionAspect extends the SQLException message with the SQL command
 * of the exception-causing Statement class.
 * 
 * Because the {@link java.sql.Statement} is an interface, the incoming SQL queries
 * have to be bind to a unique field of the implementing class to assign it to the
 * exception later on.
