Cantata Hybrid - Certification for Google Tests

Cantata Hybrid, a subset of Cantata, is the world’s first certification engine for Google tests. It enables GoogleTest® and GoogleMock® suites to be executed alongside Cantata tests, generating certified results and code coverage. Cantata Hybrid eliminates the costly and time-consuming process of qualifying open-source frameworks like GoogleTest for safety standards.

With Cantata Hybrid, there’s no need to modify or migrate existing GoogleTest suites. It runs GoogleTest suites and equivalent Cantata tests in parallel, gathering detailed coverage metrics without altering the source code or requiring a new framework. It integrates seamlessly into existing workflows, producing certified results in both ASCII and HTML formats.

Cantata Hybrid supports a variety of platforms, including Windows, Linux, simulators, emulators, and physical hardware. It integrates with Visual Studio, Visual Studio Code, and GCC, facilitating cross-compilation and deployment on embedded targets.

Key Benefits:

• Cost-Effective Certification: More affordable than qualifying GoogleTest and GoogleMock for safety standards.
• Certified Coverage: 100% code coverage for all metrics required by safety standards, including MC/DC.
• Automation-Friendly: Supports batch execution via command-line interfaces, ideal for CI/CD pipelines.
• No Tool Migration: Retain existing GoogleTest suites without modification

Cantata Hybrid guarantees compatibility with the highest safety integrity levels across industries like automotive, aerospace, railways, and medical devices. It provides seamless, certified testing for critical software, reducing risks, saving costs, and accelerating development timelines.
