LDRA Software Technology

TBvision continues to advance automated code analysis and testing tools for the highly complex security-and safety-critical markets common in industry sectors such as military and aerospace, automotive, communications, infrastructure and medical.

A key feature of TBreq is its ability to capture requirements (high-level, derived and low-level) from any management tool and source, while providing an intuitive interface for traceability, test case generation and requirements verification.

All of these features combine to make TBreq the most effective solution for Requirements Coverage and Traceability on the market today.

The primary goal of unit testing is to take the smallest piece of testable software in the application, isolate it from the remainder of the code, and determine whether it behaves exactly as expected.

Each unit is tested separately before integrating them into modules to test the interfaces between modules. Unit testing has proven its value in that a large percentage of defects are identified during its use.

TBsafe provides developers, testers and managers of high integrity software with a set of analysis tools to test their code rigorously to exacting standards for example D0-178B, Def Stan 00-55 and IEC 61508. TBsafe is particularly suited to gaining certification from outside bodies.

TBevolve is an additional module to LDRA Testbed that identifies and tracks significant source code changes and enables projects to accurately monitor the impact of these code changes on their testing process.

This is achieved by taking a baseline copy of the software system under test and then highlighting the impact of subsequent code changes so that any knock-on effects from the change can be tracked and tested with minimal effort.

The TBsecure plug-in to TBvision comes complete with the Carnegie Mellon Software Engineering Institute (SEI) CERT C secure coding standard. TBsecure identifies security vulnerabilities and enables implementation of the just released CERT C Secure Coding Standard version 1.0.
