Email: info ldra. TBvision is the interactive environment for LDRA Testbed that lets you easily visualise coding standards compliance and quality metrics and rapidly address identified flaws at the source code level. With 40 years of code analysis experience in safety-critical, security-critical, and business-critical applications, LDRA Testbed and TBvision provide complete confidence for your software development project. LDRA Testbed enforces compliance with coding standards and clearly indicates software flaws that might otherwise pass through the standard build and test process to become latent problems.

LDRA Testbed provides the core static and dynamic analysis engines for both host and embedded software. In addition, test effectiveness feedback is provided through structural coverage analysis reporting facilities which support the requirements of the DOB standard up to and including Level-A.
Liverpool Data Research Associates LDRA was founded in by Professor Michael Hennell to commercialize a software test-bed created to perform quality assessments on the mathematical libraries on which his nuclear physics research at the University of Liverpool depended. LDRA Testbed is a proprietary software analysis tool providing static code analysis, and also provides code coverage analysis, code, quality and design reviews.
It is a commercial implementation of the software test-bed created by Hennell as part of his university research. It was the first commercial product to include support for the Linear Code Sequence and Jump software analysis method, which resulted from the same research.
It is used primarily where software is required to be reliable, rugged, and as error-free as possible, such as in safety critical aerospace electronics or avionics. Static analysis initiates LDRA Testbed activity by undertaking lexical and syntactic analysis of the source code for a single file or a complete system. The enforcement of programming standards or coding standards is commonly regarded as good practice.
Main Static Analysis searches the source code for any programming standards violations, by checking the source files against the superset supplied with LDRA Testbed. LDRA Testbed reports violations of the chosen set of standards in both textual reports and as annotations to graphical displays.
Dynamic coverage analysis explores the semantics of the program-under-test via test data selection. It uses control and data flow models and compares them with the actual control and data flow as the program executes. Dynamic Analysis, therefore, forces the selection of test data which explores the structure of the source code.
The LDRA tool suite includes a dynamic coverage amodule. It is used to beneficial effect on software robustness and reliability during both development and maintenance cycles. Quality metrics such as Halstead complexity measures , cyclomatic complexity , Knots metric are designed to verify that code is clear, maintainable and testable.
The quality report in the LDRA tool suite presents both a summary and detailed breakdown of quality metrics which are deduced during static analysis. From Wikipedia, the free encyclopedia.
