    Engine.IO

    Engine.IO

    Transport-based cross-browser bi-directional communication layer

    In most cases, the connection will be established with WebSocket, providing a low-overhead communication channel between the server and the client. Rest assured! In case the WebSocket connection is not possible, it will fall back to HTTP long-polling. And if the connection is lost, the client will automatically try to reconnect. Scale to multiple servers and send events to all connected clients with ease. Socket.IO is a library that enables real-time, bidirectional and event-based...

    HTTP server mocking and expectations library for Node.js

    HTTP server mocking and expectations library for Node.js. Nock can be used to test modules that perform HTTP requests in isolation.

    Jest Puppeteer

    Jest Puppeteer

    Run your tests using Jest & Puppeteer

    Most continuous integration platforms limit the number of threads one can use. If you have more than one test suite running puppeteer chances are that your test will timeout. This is because jest will try to run puppeteer in parallel and the CI platform won't be able to handle all the parallel jobs in time. A fix to this is to run your test serially when in a CI environment. Users have discovered that running test serially in such environments can render up to 50% of performance gains....

Install SuperTest as an npm module and save it to your package.json file as a development dependency. You may pass an http.Server, or a Function to request(), if the server is not already listening for connections then it is bound to an ephemeral port for you so there is no need to keep track of ports. ...
