Feature: Queries related to all Stackoverflow questions related to WSP
Scenario: Dijkstra with pre calculated cost
Given graph "wsp1"
When executing query:
"""
MATCH (a {id: 1})-[
edges *wShortest
(e, n | (e.distance * 0.25) + (e.noise_level * 0.25) + (e.pollution_level * 0.5))
total_weight
]-(b {id: 4})
RETURN startNode(head(edges)).id + reduce(acc = "", edge IN edges | acc + " -> " + endNode(edge).id) AS hops, total_weight;
"""
Then the result should be:
| hops | total_weight |
|'1 -> 2 -> 4'| 4.75 |
Scenario: Using more than one property Dijkstra
Given graph "wsp2"
When executing query:
"""
MATCH (a {id: 1})-[edges *wShortest (e, n | e.weight1 + e.weight2) total_weight]-(b {id: 4})
RETURN startNode(head(edges)).id + reduce(acc = "", edge IN edges | acc + " -> " + endNode(edge).id) AS hops, total_weight;
"""
Then the result should be:
| hops | total_weight |
|'1 -> 3 -> 4'| 17.0 |
