Feature: Setting impedance and speed separately
These tests assume that the speed is not factored into the impedance by OSRM internally.
Instead the speed can optionally be factored into the weiht in the lua profile.
Note: With the default grid size of 100m, the diagonals has a length if 141.42m
Background:
Given the profile "testbot"
Scenario: Use impedance to pick route, even when longer/slower
Given the node map
| | s | | t | | u | | v | |
| a | | b | | c | | d | | e |
And the ways
| nodes | impedance |
| ab | 1.3 |
| asb | 1 |
| bc | 1.5 |
| btc | 1 |
| cd | 0.015 |
| cud | 0.010 |
| de | 150000 |
| dve | 100000 |
When I route I should get
| from | to | route | distance |
| a | b | ab | 200m +-1 |
| b | a | ab | 200m +-1 |
| b | c | btc | 282m +-1 |

| d | c | cud | 282m +-1 |
| d | e | dve | 282m +-1 |
| e | d | dve | 282m +-1 |
Scenario: Weight should default to 1

When I route I should get
| from | to | route |
| a | b | ab |
| b | a | ab |
| b | c | btc |
| c | b | btc |
Scenario: Use both impedance and speed (multiplied) when picking route
OSRM should not factor speed into impedance internally. However, the profile can choose to do so,
and this test expect the testbot profile to do it.
Given the node map

And the ways

When I route I should get
| from | to | route |
| a | b | ab |
| b | a | ab |
| b | c | btc |
| c | b | btc |
Scenario: Weight should influence neither speed nor travel time.

When I route I should get
