VectorCAST AI Generates Unit Tests from Software Requirements
The new Reqs2x workflow maps requirements to functions, generates executable test cases, and puts every result in front of you for review before anything enters your test suite.
Reqs2x is VectorCAST 2026's new requirements-to-test workflow. It reads your requirements, maps them to the functions that implement them, generates executable unit tests, and presents both the mappings and the test cases for your review. The AI handles the mechanical work. You sign off before anything enters your suite.
How Reqs2x Works
Step 1
Map requirements to functions
Import your requirements via the Requirements Gateway. Reqs2x maps each one to the functions implementing it.
Step 2
Generate test cases
Program slicing and LLMs produce executable tests aligned to requirement specifications.
Step 3
Review and validate
Mappings and test cases are presented for user review before any test enters your suite.
Bring Your Own Model
VectorCAST 2026 supports on-premises, cloud, and hybrid AI infrastructure. You choose the model and operate your own environment. Vector provides configuration connectors. Your data stays where you put it.
