/**
 *  Define your own Connection tester if you want to
 *  override c3p0's default behavior for testing the validity
 *  of Connections and responding to Connection errors encountered.
 *
 *  Recommended: If you'd like your ConnectionTester
 *  to support the user-configured preferredTestQuery
 *  parameter, please implement {@link com.mchange.v2.c3p0.UnifiedConnectionTester}.
 *
 *  
ConnectionTesters should be Serializable, immutable, 
 *  and must have public, no-arg constructors.
