The GoogleTest Qualification Kit by Validas: Streamlining Safety-Critical Compliance

GoogleTest (gtest) is an open-source C++ testing framework broadly used for its flexibility and reliability. Originally developed by Google in 2008, it has become the industry standard for unit testing in C++ projects, including those in automotive, aerospace, railway, industrial automation, and other safety-critical fields.

GoogleTest empowers developers with features that make testing smarter and more efficient:

• Independent & Repeatable Tests
  Simplify debugging and ensure consistent results across environments.

• Detailed Failure Messages
  Get clear insights into what went wrong, reducing guesswork and speeding up fixes.

• Non-Fatal Error Handling
  Continue running tests even after minor failures, streamlining the fix-and-retest cycle.

These capabilities allow teams to focus on writing effective tests, accelerating development and delivering more reliable software.

While gtest is powerful, it was not designed for safety certification. In regulated domains, tool qualification is essential to ensure that testing results are accurate and trustworthy. Without qualification, compliance with international safety standards becomes a major hurdle.

Imagine building a bridge. You’d verify every tool used in construction, right? The same applies to software for airbags, medical devices, or autonomous systems. Tool qualification provides documented proof that gtest works as intended in your environment, mitigating risks and ensuring compliance.

The Validas QKit for GoogleTest is a sophisticated dual-component system designed for maximum reliability.

The QKit is the synergy of two core elements:

1. COSAFE (Compliance and Safety Framework): Our proprietary framework that aligns and manages requirements from leading standards like ISO 26262, IEC 61508, and DO-330.

2. gtest QualPack (Qualification Package): A tailored suite of tests and data specifically designed for the GoogleTest framework.

The Result: When combined, COSAFE + QualPack deliver a complete Qualification Kit that ensures your testing environment is audit-ready and standard-compliant.

The Validas gtest QKit delivers:

• Standard-compliant documentation

• Detailed Tool Safety Manual

• Coverage of most gtest features

It's also adaptable and extendable for your configuration.

• Accelerates compliance with ISO 26262, IEC 61508, DO-178C, and other standards

• Reduces qualification effort and cost

• Provides confidence in tool reliability

• Enables safe use of gtest in production environments

Integrating the Validas gtest Qualification Kit (QKit) into your development workflow delivers clear advantages:

• Future-Proof Compliance
  Owned and maintained by Validas, the QKit stays current with gtest updates and shifting regulatory landscapes, so you never fall behind.

• Environment-Specific Precision
  The QualPack is adapted to your unique hardware and software stack to eliminate "generic tool" gaps.

• Zero-Friction Automation
  Eliminate human error with automated test execution and analysis that cuts qualification time from weeks to days.

• Audit-Ready Documentation
  Generates documentation for ISO 26262, IEC 61508, and DO-330, this reduces time and streamlines compliance.

• The "Green Light" for Certification
  Remove the guesswork. Our structured approach provides the evidence auditors need to see.

Validas offers more than a kit. It provides end-to-end support. We help you deploy the COSAFE-backed QKit within your own environment for scalable, ongoing testing.

For organizations with limited resources or unique project needs, Validas offers Single Qualification performed entirely within our environment. No installation required, saving time and effort. Need custom coverage? We can extend the test suite to meet your requirements
