Razorcat Development GmbH was founded in 1997 by Michael Wittner and is an independent, privately owned company located in Berlin and Waldbronn. The core technology of the Razorcat products was based on prototypical testing tools developed at the research laboratories of DaimlerChrysler. Focused on software testing tools for the embedded systems market, Razorcat has developed the powerful unit testing tool TESSY for C-code modules that supports the most relevant microcontrollers, compiler environments and target platforms. The systematic test design tool CTE helps creating low redundant and error sensitive test cases. The Intergrated Test Environment (ITE) provides solutions to handle complex test management projects including the definition of requirements and dependent tests, control the test execution, evaluate the test results and finally generate test verification reports. The system test is comprehensively automated with the simple but powerful test specification language CCDL. Through the fully automated test execution and evaluation, CCDL enables a powerful and resource-friendly testing of a system.
