Rational Logiscope

• Erkennt Fehler im Softwarecode in einer frühen Zyklusphase, sodass die Entwicklungszeit verkürzt wird
• Erhöht die Codezuverlässigkeit durch Hinweis auf nicht getesteten Softwarecode
• Zeigt fehlerträchtige Module auf, die in der Regel die meisten Softwarefehler verursachen
• Unterstützt bei der Problemverhinderung und -diagnose durch die Bereitstellung von Informationen auf Basis von Softwarekennzahlen und Diagrammen
• Bietet Schablonen für Softwarekennzahlen zur Beurteilung der Qualitätsmerkmale eines Programms, z. B. der Wartungsfreundlichkeit
• Verbessert Software-Engineering-Verfahren und unterstützt Entwickler beim Umsetzen der besten Verfahren für Codeerstellung und Testen
• Höhere Wartungsfreundlichkeit und Zuverlässigkeit durch das Ermitteln von fehlerträchtigen Modulen und die Bereitstellung nützlicher Informationen auf Basis von Softwarekennzahlen, damit Sie Probleme verhindern und diagnostizieren können
• Senkt Wartungskosten mithilfe von angemessenem Code-Refactoring, wodurch Codeduplikate in Quellcodestrukturbäumen erkannt werden
• Unterstützte Betriebssysteme: Linux, Windows

IBM® Rational® Logiscope is a software quality assurance (QA) tool that helps increase test coverage by automating code reviews and the identification and detection of error-prone modules for quality assurance and software testing. Customizable software testing features help you identify bugs early in the software development process, so you can increase software quality and deliver on time and within budget.

Eliminating errors early in the software development lifecycle is crucial to maintaining software development standards, so you can meet requirements, build reliable products, and minimize time to market. Rational Logiscope identifies the modules most likely to contain bugs, connects you to the faulty constructs, and recommends improvements.

Benefits of using Rational Logiscope can include:

Early detection of software coding errors can result in significant savings in development time (coding, code reviews, and testing). Logiscope checks code against a set of project-defined programming rules early in the development process. This technique can prevent language traps and coding misunderstandings, while consistent use of Logiscope promotes overall best coding practices.

Logiscope can improve code reliability by showing software developers and QA specialists which parts of the code remain untested. For increased test productivity, Logiscope identifies inefficient test cases and regression tests that should be re-executed if a function or file is modified.

Logiscope locates the error-prone modules that are responsible for most of the errors in your software. Once these modules are found, Logiscope provides you with valuable information based on software metrics and graphs to help you anticipate and diagnose problems. Logiscope can help you can make better decisions about whether to rewrite a module or test it more thoroughly. Furthermore, Logiscope CodeReducer can help you reduce maintenance costs through appropriate code re-factoring, which identifies duplicated code across source code trees.

Software metrics templates, called Quality Models, are also used to evaluate program quality characteristics such as maintainability (as described in ISO 9126) and class reusability. These templates may be customized to meet the specific requirements of your project.

Using Logiscope at all stages of the software development cycle can improve software engineering practices and help developers achieve the best coding and testing practices. Project leaders and quality engineers can gain better insight into overall software quality.

In contractual relationships, Logiscope defines the required quality level to be attained and the acceptance tests to be performed by contractors. By using Logiscope, contractors can increase their credibility by demonstrating the quality of their software.
