Overview of LDRA Testbed 10.3
LDRA Testbed is the foundational component of the LDRA tool suite, a comprehensive platform developed by LDRA (formerly Liverpool Data Research Associates) for static and dynamic software analysis, testing, and verification. It serves as the core engine powering code compliance checks, quality metrics, unit testing, and requirements traceability in safety-critical and security-sensitive applications. Version 10.3 represents an incremental update in the LDRA ecosystem, focusing on enhanced performance, broader language support, and deeper integration with modern development workflows. Released around mid-2024, it builds on the strengths of prior versions (e.g., 10.2) by improving automation for embedded systems and cloud-based CI/CD pipelines, while maintaining compatibility with standards like DO-178C, ISO 26262, and MISRA.
LDRA Testbed 10.3 is particularly valued in industries such as avionics, automotive, medical devices, and defense, where it helps reduce development risks, automate compliance, and accelerate certification processes. It processes source code across 60+ languages (including C/C++, Ada, Java, Python, and Rust) and supports both host and target environments.
Key Features of LDRA Testbed 10.3
- Static Analysis Engine:
- Proprietary parsing for accurate detection of coding standard violations (e.g., MISRA C/C++, CERT, CWE), security flaws, and quality issues like cyclomatic complexity or maintainability indices.
- Advanced data/control flow analysis to visualize code architecture, coupling, and dependencies—essential for refactoring legacy codebases.
- Dynamic Analysis and Coverage:
- Measures structural coverage (e.g., statement, branch, MC/DC) during unit, integration, and system testing.
- Supports runtime error detection, including memory leaks, buffer overflows, and thread safety in multi-threaded applications.
- Integration and Automation:
- Seamless plugin support for IDEs like Eclipse, Visual Studio, and MATLAB/Simulink.
- RESTful APIs and scripting (e.g., Python) for CI/CD integration with Jenkins, GitLab, or Azure DevOps.
- New in 10.3: Enhanced AI-assisted prioritization of defects and auto-generated test harnesses for edge cases.
- Visualization with TBvision:
- Interactive GUI for navigating violations in context, with heatmaps for coverage gaps and drill-down views into source code.
- Customizable dashboards for metrics reporting, aiding audits and stakeholder reviews.
