Javascript mocking library for websockets
npm install mock-websocketJavascript mocking library for websockets.
This project inspired by mock-socket library, most code still the same. But targets only plain websockets.
Currently unstable, API will change.
``shell`
npm install -D mock-websocket
To use within a node environment you can simply import or require the files directly. This
option is great for phantomjs or CI environments.
`js
import { WebSocket, Server } from 'mock-websocket';
// OR
const mockServer = require('mock-socket').Server;
const mockWebSocket = require('mock-socket').WebSocket;
`
`js
// chat.js
function Chat() {
const chatSocket = new WebSocket('ws://localhost:8080');
this.messages = [];
chatSocket.onmessage = (event) => {
this.messages.push(event.data);
};
}
`
`js
// chat-test.js
import { Server } from 'mock-websocket';
describe('Chat Unit Test', () => {
it('basic test', (done) => {
const mockServer = new Server('ws://localhost:8080');
mockServer.on('connection', server => {
mockServer.send('test message 1');
mockServer.send('test message 2');
});
// Now when Chat tries to do new WebSocket() it
// will create a MockWebSocket object \
var chatApp = new Chat();
setTimeout(() => {
const messageLen = chatApp.messages.length;
assert.equal(messageLen, 2, '2 messages where sent from the s server');
mockServer.stop(done);
}, 100);
});
});
