 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 mapping test specifications, unit test scenarios, test data and code coverage verification with your high level and design requirements. TBreq interfaces directly with your management tool (DOORS, ReqPro, Word or 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 and DO-254 for Aeronautics, 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, F-35 Joint Strike Fighter 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.

TBreq and the LDRA Tool Qualification Package ensure the best ROI for your certified projects.

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 is critical. TBreq provides the most sophisticated interface to your requirements management tool. All informal changes are recorded, and any test data impacted by these changes are highlighted so that all team members can identify which data might be "suspect."

Traceability Matrix created automatically

TBreq is unique in providing end-to-end traceability reports in a single view. Analysts and project managers can see a complete picture of traceability from software requirements to design test specifications, coding and tests.

Powerful test tracking requirement

The ability to manage your test cases within TBreq is an ideal solution for your testing environments. The Test Tracking requirement within TBreq enables organisations to create links from requirements to the test data so you can:

bulletDefine manual test scenarios and link them back to the original requirements
bullet Instigate and record the test run results with the associated code coverage measurements
bullet Compare results from different test runs to see what has changed
bullet 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:


bullet Integration with the most popular third-party Requirement Management tools to increase requirements visibility and to drive traceability throughout your design, coding and testing
bullet Requirement Testing Traceability matrix generation
bullet Test Specification generation from the source code and requirements as well as automatic test case generation
bullet 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)
bullet Requirements Testing coverage analysis and impact analysis
bullet Automatic detection of requirements, source code and test data changes
bullet Upstream and downstream impact analysis which helps with regression risk management



TBreq is the easiest way to link requirements, design, development, testing and verification workflow with your Requirements Management tools and your design and development tool chain:



bulletText processing tools: Word, Excel, Access, PowerPoint, PDF, . . .
bulletRequirements Management tools: DOORS, RequisitePro, or any published XML interface
bulletProject Management tools: Microsoft Project
bulletUML tools: Rhapsody, Artisan, Rose, . . .
bulletModeling & Design tools: Simulink, Statemate, SCADE, STOOD, . . .
bulletCode files: C, C++, C#, Ada, . . .
bulletConfiguration Management tools: ClearCase, CVS, PVCS, Dimensions, SYNERGY/CM, . . .
