en50128-testing

To implement EN 50128 testing coverage, define SIL-based requirements including statement, branch, condition, and MC/DC coverage for your C programs. The framework provides reusable patterns to satisfy these coverage gates across SIL levels 0-4.

Set up fault injection testing using Unity by applying the provided reusable fault-injection test templates. These templates integrate with your C module tests to validate error handling and robustness against injected faults.

Generate EN 50128 coverage reports by running Unity-based unit tests and interpreting the resulting gcov and lcov outputs. This process provides the metrics needed to verify statement, branch, and MC/DC coverage compliance.

Yes, EN 50128 testing requires traceability to requirements. The framework helps maintain test traceability by mapping your Unity-based unit and integration tests directly to defined software requirements across the V-Model lifecycle.

Yes, you can use Unity test patterns for C program integration testing at SIL 4. The framework outlines testing methodologies and reusable patterns specifically designed to support safety integrity levels ranging from 0 to 4.

Limitations of using Unity for EN 50128 testing include its focus on C programs and reliance on external tools like gcov and lcov for coverage reporting. The framework provides templates and patterns but requires manual integration into the V-Model lifecycle.
