Cantata -Hybrid Safety Standards Compliance for GoogleTest®
Cantata Hybrid enables the execution of tests by utilizing non-Cantata test suites, such as GoogleTest® and GoogleMock®, as input sources. This capability allows the generation of Cantata test results evidence, seamlessly combined with code coverage data obtained from a certified unit test tool to comply with all major safety-critical standards
Introducing Cantata Hybrid: the world’s first certification engine for Google tests.
This specialized subset of Cantata is a cost-effective alternative that allows developers to run existing GoogleTest suites to generate test results evidence and code coverage from a certified unit test tool.
Key features of Cantata Hybrid include:
Cantata Hybrid bridges the gap between open-source testing and safety-critical software development, enabling you to achieve functional safety compliance with your existing Google test.

Cantata Hybrid is a specialized subset of Cantata® that enables tests to be run with non-Cantata test suites (i.e., GoogleTest® and GoogleMock®) as inputs to generate Cantata test results evidence combined with code coverage from a certified unit test tool. The Cantata Core Product, including Cantata Hybrid, has been independently certified by SGS-TÜV GmbH as suitable for use at the highest safety integrity level for all the main software functional safety standards. This hybrid of Cantata & GoogleTest delivers a fully automated certification engine for Google tests. Cantata Hybrid does not require users to learn Cantata or to modify their existing GTest suites or mock objects and how they are built and run.
Cantata Hybrid is invoked on the command line for scripted batch execution. It utilizes the certified Core Component Cantata Compiler Driver and Instrumenter (CPPCCD) to set Cantata directives and options, including code coverage, in order to build a test executable from inputs dened in a GoogleTest suite. A deployment of the Cantata library for the target environment is linked with the source code and the GoogleTest suite. As this hybrid test exe runs, it executes all the GoogleTest and GoogleMock macros from the GoogleTest suites in parallel with their equivalent Cantata test framework directives, gathering Cantata code coverage achieved by each test. Cantata Hybrid runs both the standard Google tests and equivalent Cantata tests in parallel, producing results for each, along with both detailed and aggregate code coverage results for all test suites. Coverage reports are generated in certied formats using the Cantata utility (CPPGETCOV).
Google tests under Cantata Hybrid can run on any target platforms for which Cantata target-specific deployments have been made available (simulators, emulators, or physical target boards). When the test exe is run on a target, the functional and code coverage test results are directed back to the host for report generation. A copy of the source code under test is instrumented with Cantata test directives and code coverage, ensuring that the production code is never modified for testing.
