Unit Testing Legacy Code: Effective Approaches

Unit Testing Legacy Code:
Effective Approaches

FREE Ebook

Probably most of your applications consist of “legacy code”: code that was written sometime in the past, in accordance with some now obsolete standard (or, in some cases, to no apparent standard at all). As a result, legacy code often carries a lot of technical dept – which is why legacy code often has a bad reputation.

But, because we recognize those existing applications are among our organizations’ most valuable resources we continue to extend them and add new functionality. Part of that continues process is making sure that the legacy code will continue to work as expected after any new functionality is added.

Our new ebook will help you learn the most effective approaches and tools for unit testing legacy code.

In fact, using the current set of commercially available development and mocking tools, you have at least two strategies for leveraging automated testing to ensure that the changes you make to your existing code base meet (and continue to meet) your quality standards.

Join Peter Vogel, a proven expert in the field, and see these strategies in practice with real case studies and examples.

If you download the ebook, we will follow up soon with more practical resources on the topic.
