VectorCAST is a comprehensive test-automation suite designed to streamline unit, integration, and system testing across the embedded software development lifecycle. It automates test case generation and execution for C, C++, and Ada applications, supports host, target, and continuous-integration environments, and offers structural code coverage metrics to help validate safety- and mission-critical systems. It integrates with simulation workflows such as software-in-the-loop and processor-in-the-loop, links to model-based engineering tools like Simulink/Embedded Coder, supports white-box testing features like dynamic instrumentation, fault injection, and test harness generation, and can combine static-analysis results (e.g., from Polyspace) with dynamic test coverage for full-lifecycle verification. Key capabilities include linking requirements to tests, managing and reporting coverage across configurations.
