Rational Logiscope

IBM Rational Logiscope is a software quality assurance tool that automates code reviews and the identification and detection of error-prone modules for software testing.

• Detects software coding defects early in the life cycle, which can help reduce development time
• Improves code reliability by indicating untested software code
• Locates error-prone modules, the ones that are typically responsible for most software errors
• Helps you anticipate and diagnose problems by providing information based on software metrics and graphs
• Provides software metrics templates for evaluating program quality characteristics, such as maintainability
• Improves software engineering practices and helps developers achieve the best coding and testing practices
• Helps reduce maintenance costs through appropriate code re-factoring, which identifies duplicate code across source code trees
• Helps improve maintainability and reliability by locating error-prone modules and providing valuable information based on software metrics to help you anticipate and diagnose problems
• Helps reduce maintenance costs by appropriate code re-factoring by identifying duplicated code across many source code trees
• Operating systems supported: Linux, Windows

View 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 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.
