Feature: Basic Roundabout
Background:
Given the profile "testbot"
Given a grid size of 10 meters
Scenario: Enter and Exit
Given the node map
| | | a | | |

And the ways
| nodes | roundabout |
| ab | false |
| cd | false |
| ef | false |
| gh | false |
| bcegb | true |
When I route I should get
| waypoints | route | turns |
