Which software safety standards require software unit/integration testing?

International software safety standards require evidence of low level (unit and integration) testing to obtain certification for the device software.

Cantata is a unit test tool for embedded C/C++ software, certified by SGS-TÜV SAAR as suitable for use at the highest Safety Integrity Levels of all these standards:

  • ISO 26262

    Road vehicles – Functional safety

  • IEC 60880

    Nuclear Power

  • IEC 62304

    Medical device software – software life cycle processes

  • EN 50657

    Railway applications – Rolling Stock Applications – Software on Board Rolling

  • EN 50128

    Railway applications – Communication, signaling and processing systems

  • IEC 61508

    Functional Safety of Electrical/ Electronic/ Programmable Electronic Safety-related Systems

  • DO-178 B/C

    Software Considerations in Airborne Systems and Equipment Certification

Cantata provides all capabilities required for embedded software testing standards compliance, including: unit testing, integration testing, code coverage, execution on host or target hardware environments, and automated regression testing for integration with DevOps and CI/CD workflows.

"Module testing early during development is becoming more important due to the increasing complexity of software. In practice Cantata has proved successful and increased unit testing efficiency. Cantata from QA Systems offers an ideal solution for the creation and execution of unit and integration tests, including coverage analysis."

How does Cantata work?

  • Cantata provides an integrated test framework (test scripts and a supporting library) that enables any combination of testing styles for both unit and scalable integration testing.
  • Tests can be edited in a GUI or directly as C/C++ code, and run as executables on both host and multiple target platforms.
  • Tests are built with the code under test, using your standard build mechanism and downloaded to run on a target platform.
  • Cantata test scripts can be generated from one or more selected source code files. The source code is parsed to obtain a comprehensive model (.csi file) of the code, so structured tests can be generated from it.
  • Cantata provides an integrated test framework (test scripts and a supporting library) which enables any combination of testing styles for both unit and scalable integration testing.
  • All Cantata related files are stored in the “Cantata” directory at the top-level of a project. This allows the test files to co-exist with your source files in a self-contained hierarchy and to be easily managed using version control tools.
