Model-Based Test Design for Complex Industrial Systems
Yest, developed by Smartesting, is a model-based test design solution that helps engineering teams improve the relevance, coverage, and maintainability of system tests.
Yest supports organizations in sectors such as aerospace, defense, rail, energy, automotive, and medical devices, where requirements traceability, systematic verification, and quality assurance are essential.
From Requirements to Model-Based Tests
Yest enables test engineers to visually model functional tests in order to validate system behaviors, functional chains, and associated engineering data. It automatically derives relevant test scenarios from its models.
Yest helps engineering teams:
- Improve requirements traceability and coverage: Link Test Cases to system requirements and identify coverage gaps.
- Manage test complexity: Generate combinations of test scenarios on the basis of visual test workflows and decision tables.
- Optimize test development and maintenance: Reuse existing models and scenarios, automate repetitive design activities, and propagate changes more efficiently.
- Deliver test automation: Generate keyword-driven test procedures for manual or automated execution on your test benches.
Integration with Siemens Polarion
Yest complements Polarion by extending the engineering toolchain with dedicated model-based test design capabilities.
Requirements managed in Polarion can be leveraged within Yest through the appropriate linkage with Work Items, enabling V&V engineers to design, review, and optimize test scenarios in relation to system requirements.
This approach enables engineering organizations to distinguish test design from test implementation, start verification activities earlier, improve collaboration between systems engineers and test teams, and reduce the effort required to maintain test assets as requirements evolve.
Designed for Industrial V&V
Yest is particularly well suited to industrial projects involving complex functional behavior, numerous configurations across multiple integrated systems, and demanding verification & validation requirements.
Its visual test models help teams understand test scenarios and strategies. By combining model-based test design with requirements traceability, Yest helps organizations establish a more systematic, maintainable, and auditable V&V process.
Agentic AI for Industrial V&V
Beyond model-based test design, Yest also leverages an agentic AI approach to assist engineering teams throughout the verification and validation process.
Unlike generic AI assistants that simply generate test cases from text prompts, Yest's AI companion operates on structured engineering data, including system requirements, functional chains, and existing test assets. It uses specialized AI agents to help engineers explore requirements, identify relevant information, analyze functional coverage, and propose model-based test scenarios directly within Yest while guaranteeing explicability, security, and data source integrity.
