Detailed Description

PathComputationTest implements a majority of the cucumber tests for the Path Computation Engine (PCE). The interesting scenarios are around the following areas:

  • validate that kilda honors the various path computation scenarios
  • there should also be path edge cases that are tested, in order to validate the user experience - eg when a flow is requested that doesn't exist (bandwidth limitation or just no path). However, a few are already implemented in FlowPathTest.

In order to test the scenarios, we use a special topology: 

 1 - 2 - 3 - 4 - 5 - 6 - 7
     2 -- 8 - - 9 -- 6
     2 - - - A - - - 6
     2 - - - - - - - 6

This is to ensure that, as we vary the hops (path length) we also very the the path used.

  • For hop count, 2-6 should win.
  • For latency, 2-A-6 should win (we'll configure it as such)
  • For cost, 2-8-9-6 should win (again, we'll configure it as such)
  • For external, 2-3-4-5-6 should win (based on configuration)

To run just the tests in this file: 

 $> make atdd tags="@PCE"

Other Notes:

  • Look at FlowPathTest for some of the edge cases related to not enough bandwidth, etc.
