AI-assisted test design: from your requirements to your test models
AI suggests, engineers decide.
How does Yest Companion work?
Yest’s AI companion builds on your requirements, functional chains and engineering data. You ask it questions in natural language to define the test scope and strategy, it suggests workflow elements linked to your verification objectives, and you make the call.
An engineering foundation traced end to end
Ask it in natural language
It suggests model elements
You stay in control
Yest generates traceable tests
What are the benefits for your industrial projects?
Thousands of requirements, controlled test design, and an AI that stays under control.
Direct access to system requirements
Control over test coverage
Augmented, model-driven design
A trusted AI, under the engineer’s control
Which industrial projects is it for?
Yest Companion is designed for systems where verification leaves nothing to chance, and for teams who need to get up to speed fast.
Complex systems
Elaborate functional chains, cascading requirements, high test combinatorics, and a traceability requirement across all engineering assets.
Draws on your requirements and traced functional chains to suggest workflow elements linked to your verification objectives.
Sensitive environments
Projects under strict cybersecurity constraints, where AI must run locally and provide the control and review mechanisms that build trust.
Runs on a local LLM with no data sent to a public network, and every suggestion remains traced and subject to your approval.
Teams getting up to speed
Newcomers, subcontractors or rotating teams who need to quickly understand the requirements and test strategies linked to a function.
Answers in natural language, directly in Yest, based on your project’s requirements and engineering data.
Yest Companion meets the trust requirements of industrial projects
Confidentiality and sovereignty
Can operate on a local LLM, with no data sent to a public network.
Traceability and audit
Every result comes with traces explaining how the agent arrived at its answer.
Reliability of requirements data
Structured queries, powered by a data templating mechanism: the agent doesn’t “guess” the requirements.
Human accountability
“The agent may propose, never decide. The human decides, so the human justifies.”
Why choose Yest Companion over a generic AI?
A generic AI generates tests. Yest Companion strengthens your test model, on your data, under your control.
