Our Company

Our mission is to put quality into C. We do that by improving the quality of C and C++ compilers, libraries and analysis tools, and by enabling their safe and secure use. With the quality level of our test suites, we stay at the forefront of software testing and qualification to help you achieve ISO compliance and functional safety standard requirements.

Founded in 2014, Solid Sands is headquartered in Amsterdam, The Netherlands. With partners all over the world we serve both leading innovative companies in the semiconductor, IP and security industries as well as safety-critical companies in automotive, robotics, railway and medical.

Our SuperTest Compiler Test and Validation Suite provides a complete validation environment which enables customers to achieve the software quality level demanded by the ISO language and functional safety standards.

Meanwhile, our SuperGuard Library Safety Qualification Suite is a requirements-based test suite for the standard library with full traceability between the requirements derived from the language definition and the individual library tests.

The history of Solid Sands

Aelbert Cuyp was one of the great Dutch 17th-century painters; although primarily known for his landscapes, also excelled in portraits and depictions of animals. SuperTest aspires to be versatile like Aelbert Cuyp and can be used with any combination of compiler and target, covering language and library specifications from C89 to C++20.

Solid Sands 5 Year Anniversary

Johannes Vermeer is known for his photorealistic attention to detail using pigments such as lapis lazuli to create a world more perfect than the real one. It is still a mystery how he was able to achieve the masterly treatment of light and color in his work, since the appreciation of his paintings came only two centuries after his death. SuperTest aims to attain the same perfection as Vermeer, but without the mystery.

Solid Sands Starts

Solid Sands starts in November 2014 and has its headquarters in Amsterdam, the Netherlands. Our mission is to put quality into C. We do that by improving the quality of C and C++ compilers, libraries and analysis tools, and their safe and secure use, with the best possible test and validation suite.


SuperTest Started

When SuperTest started, there was only K&R C. As ISO standardization progressed, SuperTest was extended to track the latest developments. We plugged holes in the suite by adding tests for errors not initially found. We created generators to add systematic testing for complex parameter spaces. SuperTest is now the most complete validation suite for C and C++ available.
