Introduction

When our code eventually runs as a production job, it is expected that it will be robust, reliable, and bug free. For this to happen, it will usually pass through various stages of testing, including the unit test stage performed by the developer.

This section shows some of the methods that can be used to ensure that developers can find and fix problems quickly during this testing phase.

Debugging

The ability to find and locate issues within code quickly and efficiently is the key to successful delivery of projects. Talend provides methods for debugging, and so does Eclipse.

Logging

Talend provides useful components for logging and capturing errors in tWarn, tDie, and tFlowMeter. It also provides mechanisms for logging information to the console, which can be a quick and valuable debugging tool, and is a vital part of the developers' armory. It is often quicker to send and view messages and information to the log output during development than it is to do the same to say a database...
