Cantata Test Architect

Accelerate your
unit & integration testing

Automated unit & integration testing for C & C++

Cantata is a unit and integration testing tool, enabling developers to verify standard compliant or business critical code on host native and embedded target platforms.

Cantata helps accelerate compliance with the standard’s dynamic testing requirements by automating:

  • Test framework generation
  • Test execution
  • Results diagnostics and report generation

Cantata is integrated with an extensive set of embedded development toolchains, from compilers and static analysis tools to build and requirements management tools. The ECLIPSE® GUI, tight tool integrations and tests written in the source C/C++ code, all make Cantata easy to use.

"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."

Matthias Schmidt, Test management, Verification and Validation,
Bosch Engineering GmbH

"Through years of experience in unit testing using Cantata for various platforms and languages… we are confident in suggesting Cantata to our clients."

Padmakumar TV, Senior Engineering Specialist,
TATA Elxsi

"No-one pretends that Unit Testing is the most interesting activity in the world, but that's all the more reason why we need tools that are usable and reliable, which yours are."

Safety standards testing compliance

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

In addition, most standards require that test tools used are certified / qualified or proven through use. Cantata has been independently certified by SGS-TÜV SAAR GmbH for the main software safety standards. Standard specific Cantata tool certification kits are provided free of charge and contain everything needed out-of-the-box as well as comprehensive guidance to help you achieve certification for your device software. Tool qualification of Cantata is also available where tool certification against a standard is not permitted as the tool must be qualified separately for each project (e.g. for DO-178B/C).

Over the last 20 years Cantata has been successfully used to comply with the testing requirements of:
