RPC Mock

This is a module for incercept and manipulate Kong's RPC calls between CP & DP.

CP

Visually we will get a mocked CP by calling:

local mocked_cp = require("spec.helpers.rpc_mock.cp").new()
mocked_cp:start()

This starts a working Kong CP, with all the funcitionalities and acts like normal CPs, except for that it can be manipulated with the mocked_cp object.

Arguments can be used to alter the control planes's options (or attach to an existing CP) or not to start incerception by default, etc.

Then we can let CP make a call to a specific node connected:

local res, err = mocked_cp:call(node1_uuid, "kong.sync.v2.notify_new_version", payload)

And we can incercept a call to the mocked CP:

for _, record in pairs(mocked_cp.records) do
    print("DP ", record.nodeid, " made a call ", record.method)
    print(plprint(record.request))
    print(plprint(record.response))
end

We can also mock an API. (Note that the original handler will be overrided.)

DP

This is bascially an extended version of kong.clustering.rpc.manager.

Added API:

local mocked_dp = require("spec.helpers.rpc_mock.dp").new()
mocked_dp:try_connect()
mocked_dp:wait_until_connected()
assert(mocked_dp:is_connected())
mocked_dp:stop()
