PAT-075 - TRR - Software Test Readiness Milestone Review Checklist

AI (gpt-4o)

The Software Test Readiness Review (TRR) exit criteria, as outlined in NASA-HDBK-2203 Topic 7.09, lay out the necessary conditions that must be met before software testing can begin. The TRR ensures that all preparations for testing—such as software, hardware, test environments, and documentation—are complete and that the team is ready to proceed with testing activities. The focus is on validating that the planned tests will address requirements, identify defects, and measure performance and functionality effectively. Below is a summary of the Software TRR Exit Criteria:

Summary of Software TRR Exit Criteria

1. Test Objectives and Scope:
   • Clearly defined test objectives must be aligned with the requirements and mission objectives, ensuring that testing will validate software functionality, performance, reliability, and safety.
2. Test Plans and Procedures:
   • Test plans, procedures, and scripts must be complete, reviewed, and approved.
   • These documents should detail the schedules, test cases, specific steps, expected results, and acceptance criteria.
   • Procedures must ensure adequate coverage of all functional and non-functional requirements.
3. Requirements Traceability:
   • All software requirements, including functional, performance, and safety requirements, must be traceable to corresponding test cases.
   • Gaps in test coverage, if any, should be identified and addressed.
4. Readiness of Test Artifacts:
   • All test inputs, such as test cases, test data, sample scenarios, and associated documentation, must be prepared and validated.
   • Expected outputs and success criteria for tests must be clearly defined and documented.
5. Test Environment Validation:
   • The test environment, including hardware, simulators, testbeds, facilities, and tools, must be set up and verified for accuracy and consistency.
   • Environment configurations should mimic operational conditions as closely as possible.
6. Software Baseline Readiness:
   • The software to be tested must be complete, stable, and built to the appropriate configuration baseline (commonly the integration or pre-release version).
   • The software should be free of critical defects that would block testing.
7. Interface Readiness:
   • All software interfaces, both internal and external, must be defined, implemented, tested, and validated to enable testing activities.
   • Any dependencies on external systems or hardware should be met and functional.
8. Issue and Risk Management:
   • All known software issues, risks, and non-conformances must be documented and assessed for their impact on testing.
   • Risks that could impact the testing process should have mitigation plans in place.
9. Test Team Preparedness:
   • Personnel involved in the testing should have adequate training and a clear understanding of their roles and responsibilities.
   • The team should be prepared to follow the test procedures and handle anomalies during testing.
10. Configuration and Quality Assurance Readiness:
    • Configuration management must be in place to ensure traceability and control over changes to software, test plans, and test artifacts.
    • Quality assurance plans or processes must confirm that testing will be conducted in compliance with relevant standards.
11. Approval to Execute Tests:
    • Stakeholders (e.g., project managers, software assurance teams, and engineers) must review and formally approve the readiness to enter testing based on the status of test plans, procedures, and test environment setup.
12. Problem Reporting and Tracking:
    • A system for identifying, tracking, and resolving test anomalies, failures, or defects must be established and ready to be used during testing.
13. Documentation Completeness:
    • All pre-test planning documents, including test plans, configuration information, safety assessments, and operational checklists, must be provided, reviewed, and approved.

Key Purpose of Software TRR Exit Criteria

The TRR exit criteria ensure that the project team has completed all necessary preparations to begin software testing with confidence. Meeting these criteria validates that:

• The testing process is planned and executable.
• The software and test setup are stable and ready.
• All requirements are adequately covered by test cases.
• Stakeholders are confident in proceeding to the testing phase.

By thoroughly addressing the TRR exit criteria, NASA ensures that testing will be efficient, minimize risk, and provide meaningful results to validate the software's readiness for deployment.
