The Role of Test Suites in ADS Validation
In the lifecycle of automated driving system (ADS) development, one of the key challenges is maintaining performance consistency while evolving the system across versions. As new features are added and improvements are made, ensuring that no regressions occur becomes critical. This is where test suites—curated and repeatable collections of scenarios—come into play.
Test suites enable structured, consistent, and traceable validation by grouping together scenarios that reflect both common driving situations and edge cases. They serve as the backbone of regression testing, allowing teams to evaluate specific ADS functionalities against a stable reference set.
Creating and Managing Test Suites with ReplicaR
The TestSuites module in ReplicaR enables users to compile scenario collections tailored to their test goals. Scenarios can be selected from those previously created in MyScenarios and AutoScenarios, ensuring seamless integration across the toolchain.
Users can combine individual scenarios based on system requirements or functional goals—such as urban driving, highway merging, or pedestrian interaction. Default test suites (e.g., Platooning and PEGASUS-compliant suites) are also available to provide industry-standard coverage out of the box.
From Custom Validation to Regression Testing
With TestSuites, users benefit from:
- Rigorous Regression Testing: Scenarios can be re-executed across software versions to detect behavioral drift or failures introduced by changes.
- Functional Testing: Dedicated test suites can be constructed to target specific modules—like perception, planning, or control—for focused performance validation.
- Customization: As system needs evolve, test suites can be easily updated with new or adjusted scenarios to match the current validation scope.
All test suites can be exported in OpenSCENARIO® format, ensuring interoperability and enabling usage across simulation environments.
Conclusion
TestSuites close the validation loop by providing a repeatable and structured way to test the Automated Driving System under realistic and reproducible conditions. They help teams move from ad-hoc testing to systematic, scenario-based evaluation—a critical step toward achieving robust, reliable, and safe ADS deployments.
