If embedded software is the main differentiator in your products, or critical to the running of your business, you want to deliver software reliability through cost effective testing.
Industry leaders across all safety related and business critical sectors, have already invested in Cantata. Every day they are getting a competitive advantage over those yet to benefit from automated unit and integration testing.
To continue testing the hard way with manual tests, in-house or legacy tools, can be a lot more expensive than buying a suitable tool that makes your testing effective and efficient.
Investing in Cantata makes doing unit and integration testing easier, enabling organisations to:
Cut the cost of standards compliance
Reduce the risk of software failure
Lower testing costs
Shorten time to market
"Using this approach we have improved from three days for the detection and correction of each error, down to one day. This includes the time for identifying the error, making the relevant changes to the code, and re-running the low level tests."
Michael Zeiner, Dr. Keil Informationstechnik GmbH & Co KG
“The systematic use of Cantata has enabled us to have the shortest unit test phase possible with great efficiency in terms of cost.”
Philippe Lomazzi, Head of Software Development Meggitt
"Speaking conservatively this product has probably paid for itself twice over already. Initially we were a bit reluctant to consider spending what for us represented a large part of the development budget, but I am glad to say the decision was a good one."
Michael Zeiner, Dr. Keil Informationstechnik GmbH & Co KG
Why unit test with Cantata?
By testing units (defined as the smallest testable part of an application) Cantata pinpoints failures more precisely than larger system tests on complex applications. This means that errors can be fixed quickly and cheaply. Complex applications will always be more difficult and expensive to integrate and system test when the component units do not work correctly, so testing the units reduces these downstream costs and makes them more predictable.
Why integration test with Cantata
Cantata enables developers to test the interactions between units working as a group. Cantata integration tests can be performed with software (SiL), hardware (HiL) or processor (PiL) in the loop, with no technical limitation on scalability.

How can Cantata cut the cost of standards compliance?
Certification of development tools can be a heavy compliance cost burden. Cantata has been independently certified by SGS-TÜV SAAR GmbH providing a tool certification kit with everything needed out-of-the-box, available free of charge.
Compliance with the dynamic test requirements of software safety standards is complex and time consuming. Cantata provides comprehensive guidance on how to use its powerful feature set to accelerate meeting all standard specific test requirements.
How does Cantata reduce the risk of software failure?
Product recalls and infection of the wider brand and corporate reputations, can far exceed the development cost of individual applications. Unit testing is the most thorough way to test application code and prevent bugs in shipping devices.
Project over-runs can be mitigated by shifting verification earlier in the lifecycle to unit testing, reducing the risks of delays when integrating proven components.
Fitness for purpose litigation against companies and individuals is now an increasing risk. Where companies fail to employ accepted industry practices like thorough unit testing with Cantata, they cannot use the “state of the art” legal defence against such litigation.
How will Cantata lower my testing costs?
Testing earlier lowers costs by minimizing re-work dependencies on the whole code stream. Developers can immediately identify defects with Cantata unit and integration testing as soon as each component is available.
The high cost of unit and integration testing standard compliant software can be dramatically lowered through automation. From framework set-up through test case generation and execution on host/target platforms to diagnostics and results production, Cantata automation makes these cost effective.
Integrating tools into a toolchain can have hidden testing costs. Cantata’s tight integration with cross-compilation environments and intuitive C/C++ code tests in Eclipse GUI or code editors, make it easy to slot into any toolchain, and fast for developers to learn.
How does Cantata shorten my time to market?
Industry leaders recognise the need to ship faster without endangering quality. Cantata tests provide two key time advantages for Development Managers. Team collaboration and efficiency is improved with structured consistent tests and certification ready reports. Integration times are more predictable and shorter when integrating tested individual software components.
Why Cantata is better than any ‘free’ open source tool?
Cantata is pre-certified for many safety related standards; open source tools can be qualified or certified as suitable or usable in a safety related context. However the costs associated with such an exercise (defining requirements for the tool, developing and running tests against those and demonstrating the tool operates correctly in the end users environment), are prohibitive.
Existing investment in legacy open source test scripts implemented in C/C++ (e.g. CppUnit and CxxTest), generically known as xUnit can be re-used and embedded inside Cantata tests. This has the advantage of retaining all the existing test cases, whilst supplementing them with the more powerful features of Cantata.

How much will it cost to invest in Cantata?
Cantata comes with comprehensive user documentation, the Eclipse user interface and tests in the C/C++ languages together with tool integrations actively reduce the tool learning curve. A one-year maintenance and support contract is included as standard with most licence packages and includes free upgrades as well as dedicated help from our team of experts. A 2 Day on-site training course can also be provided to kick start tool roll-out.
