artillery-engine-socketio-v2

Socket.IO v2 engine for Artillery

Disclaimer

The default socket.io engine does not timeout the acknowledge which I am using it as RPC function. So, I have to create our own engine to support the requirement.

Acknowledge

I also tweak the code to make acknowledge to take timeout into account the same as response because I have implemented RPC using socket.io.

Report

Timeout

The original library, the timeout report is accumulated value which might not give us more detail in which channel is slow. So, I have extended the error message by adding channel into the error message. So, the repoert will have its own section.

Does not match

When the result does not match, we just get error like Failed match which sometimes it does not give us the context why it does not match. So, I put the handle to capture the error code. So, the report will contain more context why it does not match

Install & Configure

Install with npm

npm install -D artillery-engine-socketio-v2

Enable the socketio-v2 engine by listing it in config.engines. Ex:

config:
  target: "http://localhost:3000"
  phases:
    - duration: 30
      arrivalRate: 5
  engines:
   socketio-v2: {}

In each scenario you must list the engine socketio-v2 as well. Ex:

scenarios:
  - name: My first scenario
    engine: socketio-v2
    flow:
      - emit:
          channel: "echo"
