Requirements Traceability with TBreq®

What is TBreq?

Requirement Testing and Verification

TBreq, through its integration with the LDRA tool suite which includes LDRA Testbed® and TBrun® (unit testing component), is a unique solution that can help your team overcome the challenges of allocating requirements to team members, mapping requirements to design and source code, linking test cases to requirements and the generation of verification reports. TBreq interfaces directly with your management tool (Telelogic DOORS®, IBM® Rational® RequisitePro®, Microsoft® Word or Microsoft® Excel) to ensure traceability across your software lifecycle and the completeness of your requirements coverage.

Within the LDRA tool suite, TBreq creates test specifications and executable test cases directly from requirements. Test results are automatically returned to the requirements management tool to provide "round-trip requirements traceability verification."

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 Management on the market today.

Compliance with your Certification Standards

Qualification represents the agreement from Certification Authorities to reduce or replace manual activities with tool results and verifications.

TBreq complies with the most demanding quality standards: CMMI, DO-178B for Avionics, EN-50128 for Railway transportation and IEC 61508 for Automotive to name a few. The tool is compliant with the AIRBUS process for A380 & A340 projects, Boeing 787, F-35 Lightning II, NASA CEV and other major projects.

TBreq is qualifiable according to all of these standards, and LDRA can assist in this qualification process. LDRA also offers a DO-178B Tool Qualification Pack to assist in the certification process.

All of these features combine to make TBreq the most effective solution for collaborative requirements-based development and verification on the market today.

Automate Your Requirements Testing Matrix

The ability to manage changing requirements and testing

Requirements are an essential building block of a project and hence managing change to requirements are critical. TBreq provides an easy to use and configure interface to your requirements management tool. Allocating requirements and verification artifacts are made visable across a network of user workspaces. All informal changes and test results are recorded, so that all team members can identify which data might be "suspect."

Traceability Matrix created automatically

TBreq is unique in providing end-to-end, graphical traceability reports in a single view. Analysts and project managers can see a complete picture of traceability from software requirements to design, code, test specifications and test results. All reports are exportable to Word documents and easily customised to meet project needs.

Comprehensive verification tracking

The ability to define and manage analysis, implementation and test verification tasks within TBreq is an ideal solution for automating what has been historically a manual verification process. TBreq enables organisations to create links from requirements to analysis and test activities so you can:

  • Define analysis scenarios, such as automated code reviews and link them back to the original requirements
  • Instigate test runs and record test run results with the associated code coverage measurements
  • Automate defects logs and generate non-conformance documentation
  • Interrogate requirements for requirements coverage and test status

Benefits of using TBreq

TBreq provides the features required by Quality and Certification standards for multi-level and bi-directional requirements traceability and impact analysis:

  • Integration with the most popular third-party Requirement Management tools to increase requirements visibility and to drive traceability throughout your design, coding and testing
  • Requirement testing traceability matrix generation
  • Automated generation of test verification plans and reports
  • Test Specification generation from the source code and requirements as well as automatic test case generation
  • Seamless integration with LDRA Testbed® (for code review, quality review, design review and code coverage analysis) and TBrun® (for automated unit testing including test harness generation, test case generation, test report creation, Host/Target test execution and test regression)
  • Requirements structural coverage analysis and impact analysis
  • Automatic detection of requirements, source code and test data changes
  • Upstream and downstream impact analysis which helps with regression risk management
