integrated with Polarion
Accelerate Polarion test design with AI-augmented Model-Based Testing
Transform your Polarion requirements into visual, comprehensive, traceable, and maintainable test suites with Yest.
Design, generate, and automate your functional tests while maintaining full traceability and test coverage.
Polarion structures your requirements
But how can you maintain thousands of test cases?
As systems become more complex
Requirements multiply
Variants increase exponentially
Test cases become difficult to maintain
Actual test coverage becomes harder to control
The result
The value of combining Yest and Polarion
Complete digital continuity
Requirements → Test Model → Test Procedures → Automation / Execution → Coverage
Measurable results for your organization
Concrete benefits at every stage of your testing process.
Significantly reduced maintenance effort
The model becomes the single point of maintenance.
No more manually updating hundreds of test cases.
Faster coverage in Polarion
Each requirement is linked to the model and test scenarios generated by Yest.
Faster audits
The complete traceability chain is immediately available.
Earlier defect detection
Automatic test scenario generation makes it possible to explore more combinations related to product variants.
Thales uses Yest and Polarion throughout the IVVQ lifecycle
Yest acts as a model-based, AI-augmented IDE for testers.
Visual modeling
Validation, qualification, and acceptance testing of systems (MIL, SIL, HIL).
Automatic test generation
