Description

List of use cases: https://docs.google.com/document/d/1YG-ENiJE3GbOxFognhgKBWg0Bs8HviOpE2qoiCTbw0w/edit?tab=t.0

Purpose

Prepare a set of scenarios that can be used to demonstrate the PoV software stack's performance to potential customers.

Possible approaches

• Create the Gherkin description of the functional scenarios.
• Convert matching CARLA maps to LL2.
• Create test scenarios based on the Gherkin descriptions in Web.Auto's Scenario Editor.
• Convert the scenario to a CARLA compatible format.
• Document the steps required for executing scenarios so that members of the PoV WG can prepare the demo.

Definition of done

• Gherkin description of use cases is merged in the main repository.
• Resources such as test scenarios and map files that are required for execution of tests in CARLA are available.
• Steps for executing the tests in CARLA are documented.
