Refactoring Test Data Structures

Testing is getting a more and more important phase of the development process. The sooner a problem is found in the product, the less expensive it is to correct it. Many tools have been developed for making the testing phase easier. In the beginning test sequences have a well-thought-out structure, but as the development goes on, they become less well-structured and redundant. Refactorisation [1] is a technique for decreasing this type of redundancy. In this article we are going to review a universal model which makes the refactorisation process easier. We´re also going to review a refactorisation algorithm that uses this data model.
