LDRA has developed and driven the market for software that automates code analysis and software testing for safety-, mission-, security- and business-critical markets.

LDRA was founded in 1975 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. The company is headquartered in the UK with subsidiaries in the United States, India and an extensive distributor network.

LDRA traces requirements through static and dynamic analysis to unit testing and verification for a wide variety of hardware and software platforms.

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.
