TestWaitTillHealthy tests that we indeed get a healthy network after we wait for it.
|
|
For this to be tested, a bit of a snake tail bite needs to happen:
|
|
* First we create a first simulation
|
|
* Run it as nodes connected in a ring
|
|
* Wait until the network is healthy
|
|
* Then we create a snapshot
|
|
* With this snapshot we create a new simulation
|
|
* This simulation is expected to have a healthy configuration, as it uses the snapshot
|
|
* Thus we just iterate all nodes and check that their kademlias are healthy
|
|
* If all kademlias are healthy, the test succeeded, otherwise it failed
|
