VectorCAST 2026: AI-Driven Test Automation for Embedded Software

VectorCAST 2026 is Vector Informatik’s latest embedded software testing platform, introducing AI-assisted unit test generation from software requirements while maintaining rigorous human oversight for safety-critical applications .

Key New Features in 2026

AI-Powered Requirements-Based Testing

• Reqs2x Toolchain: New AI-assisted toolset that automatically generates unit tests directly from software requirements

• Code2reqs: Analyzes source code logic and generates natural language requirements documentation using LLMs

• Reqs2tests: Creates executable unit tests from natural language requirements, with automatic bidirectional traceability links

• Human-in-the-Loop: Generated mappings and test cases require user review, ensuring compliance with safety standards

Coded Tests Enhancements

• C Language Support: Coded Tests now supports testing of C source files, with capabilities fully aligned with C++ mocking

• ATG to C++ Source: Automatic Test Generation outputs reviewable C++ source code via --vc-coded-tests option

• Native GoogleTest Support: Full feature set including TYPE, PARAM, DEATH tests, and GoogleMock assertions

Coverage & Usability Improvements

• Unified Coverage Views: Project-level and unit-level coverage displayed together, eliminating context switching

• Clang JSON Compilation Database: Native support for modern build systems

Deployment & Security

• BYOM (Bring Your Own Model): Choose preferred AI model; deploy on-premises, cloud, or hybrid

• Data Privacy: Supports fully local LLM deployment (e.g., via Ollama), preventing code/data leakage
