IBM Rational Logiscope


IBM Rational Logiscope est un outil d'assurance qualité logicielle qui automatise l'analyse du code statique.
IBM Rational Logiscope est un outil d'assurance qualité logicielle qui automatise les analyses de code ainsi que l'identification et la détection des modules exposés aux erreurs lors du test de logiciels.


• Détecte les erreurs de codage logiciel à un stade précoce du cycle de vie, avec à la clé une réduction potentielle de la durée de développement.
• Améliore la fiabilité du code en indiquant le code logiciel non testé.
• Localise les modules exposés aux erreurs qui sont en général à l'origine de la plupart des erreurs logicielles.
• Aide à anticiper et diagnostiquer les problèmes en fournissant des informations basées sur les métriques logicielles et les graphiques.
• Fournit des modèles de métriques logicielles permettant d'évaluer les caractéristiques de qualité d'un programme, par exemple la gérabilité.
• Améliore les pratiques de génie logiciel et aide les développeurs à mettre en place des pratiques optimales de codage et de test.
• Réduit les coûts de maintenance grâce à une restructuration adéquate du code qui identifie le code en double dans les arborescences du code source.
• Améliore la maintenabilité et la fiabilité en localisant les modules exposés aux erreurs, et en fournissant des informations précieuses basées sur les métriques logicielles, afin de faciliter l'anticipation et le diagnostic des problèmes.
• Systèmes d'exploitation pris en charge : Linux, Windows.

Features and benefits


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
• Increased test productivity and coverage
• Improved maintainability and reliability
• Enhanced software development process


Early detection of software coding errors
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.
Increased test productivity and coverage
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.
Improved maintainability and reliability
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.
Enhanced software development process
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.
