Although black-box tests are very important for the quality assurance of software systems, only a few methods for systematic black-box test case design have found their way into the industrial world. The Classification-Tree Method is a particularly efficient testing method for which tool support is available in form of the Classification-Tree Editor CTE. This paper introduces a new version of the CTE, namely the CTE XL (eXtended Logics). The CTE XL has been fitted with a number of methodological enhancements. These extensions are the result of the intensive use of the CTE tool in industrial practice within the last couple of years.
